By technology progress and the use of fast means of transportation, the deployment of citydwellers was possible in rural areas around the city. However, due to problems in urban centers (such as high price of housing and land, over population jamming, etc.) population is poured into the suburb and on the other side due to the existence of highways, they were able to meet their requirements easily by refering to urban centers where it was caused spread cities horizontally. Urban sprawl event was stared at the united states in twentieth century then it was taken in to place in other countries like Iran. And surely conseques of this event have had some effect on quality of life (positive or negative). The purpose of this study is to investigate the effects of urban sprawl on the quality of life and the sample is Khoramdareh city. The main question in this study is that if the urban sprawl affects on the quality of life and how much is it? Therefore, after the study and examination of the theories, concepts and approaches to the phenomenon of urban sprawl and quality of life, the global experiences in respect of sprawl and quality of life and indicators of their measurement was investigated. First in the evaluation of case study, causing factors of dispersion in Khoramdareh was analyzed and then urban sprawl was investigated by examining 13 factors in 12 urban district. It was divided into sprawl district (1, 2, 3, 4, 10, 11, 12 neighborhoods) and compact districts (5, 6, 7, 8, 9 neighberhoods). Then urban neighberhoods of Khoramdareh gradation based on sprawl from 1 until 12 dirges (11, 12, 10, 1, 4, 2, 3, 5, 7, 8, 9 and 6 neighberhoods). Also quality of life by 18 indexes and questionnaire design by 18 indexes and by filling it in Khoramdeh selected neighberhoods (1 and 11 neighborhoods from sprawl district and 6 and 8 neighborhoods from compact district) were evaluated. The number of questionnaires was calculated by Cochran formula and the number rose to 130 in the four neighberhoods of Khoramdeh and by Using of this technique, the samples were made to collect data. Then the questionnaire data were analyzed and summarized by using of descriptive statistics tools (tables and charts) and finally analyzed by using of inferential statistical techniques and the results was granted with a certain confidence level of extension. Used analysis includes: Mann-Whitney Test and t Test by using of SPSS16 software and exploratory factor analysis by using the LISREL 8.5 software. The results show that the quality of life in 1 and 11 neighborhoods (ave = 2/5) is upper than the quality of life in 6 and 8 neighborhoods (Average = 2/22), with 95 percent confidence level. And then by this 95 percent confidence level, it can be said that quality of life in sprawl neighberhoods is upper than the quality of life in compact neighborhoods. Manuscript profile -

2 - Analysis of the Effects of Urban Sprawl on Social Vulnerability (Case Study: Qazvin City Districts)
Esfandiar Zebardast Hossein GhanouniIran is a country prone to earthquakes in which so many cities have experienced earthquakes in far and near past.

Although there is a high potential for earthquakes to be destructive, the level of losses and damages of them is not solely dependent on the magnitude and the location of the earthquake, or physical aspects of buildings and urban areas. In the analysis of the impacts of natural hazards, three broad categories have been defined: 1) focus on natural hazard's biophysical impacts because of the place it occurs; 2) focus on hazard's impacts on societies that experience the hazard because of the social characteristics of those societies and 3) an approach that takes into account both of impacts. This article takes the second approach to analyze the effects of natural hazards. In this approach, social characteristics of the communities and societies, in which earthquake happens, come to center stage. Social vulnerability is one of the important aspects of earthquake risks and consequences. In addition, the progress of communication and transportation technologies and an increase in agricultural production surplus because of the Industrial Revolution has caused many rural settlers to migrate to cities. The increasing population raise in cities has led to many economic, social and environmental consequences, of which excessive horizontal and leapfrog development (which is called urban sprawl in scientific literature) is one. In this article urban sprawl is defined as: "unplanned, far-from-center and automobile-accessed growth of cities which has environmental, economic and social effects and is characterized by low density, segregation of land-uses and limited accessibility". In this research, at first theoretical literature of urban sprawl and social vulnerability were reviewed and the indicators for measuring them were chosen (13 for urban sprawl and 7 for social vulnerability) and the relevant data for Qazvin was extracted by using national census data and Geographic Information System (GIS). Then explorative factor analysis for eigenvalues bigger than 1 was conducted by using SPSS software and the indicators for sprawl were categorized into 4 factors: “density”, “configuration”, “land-use” and “accessibility” (70.22% of variance explained), and the indicators for social vulnerability were grouped in 1 factor: social vulnerability (66.9% of variance explained). Then the maps for each factor of sprawl and two main topics (sprawl and social vulnerability) were made. The correlation analysis was conducted on four factors of sprawl, social vulnerability factor (which is representative of social vulnerability altogether) and sprawl as a whole. The results show that from 4 factors of sprawl, just density factor has a significant correlation (0.801) with social vulnerability. Sprawl is also significantly (although weaker) correlated to social vulnerability (0.44). In addition, regression analysis showed that four factors of sprawl can explain 67.6% of the variance of social vulnerability. The relation between social vulnerability and density/sprawl is positive/negative, i.e. by an increase in density/decrease in sprawl, social vulnerability increases. Finally, the maps of sprawl and social vulnerability in Qazvin city districts and the map of potential districts for development are shown based on the correlation of sprawl and social vulnerability.

Historical district of this city, according to the city's cultural background and based on its climate features, is an example of specific structure and compact form of a city. While the form of development in the past was interactive with the climate and environment conditions, today, the development pattern of Yazd is converted to dispersal mode and unbalanced growth pattern; this pattern have made lots of urban form in different zone of the city. The purpose of this paper is to investigate construction density with respect to population density, distance to central business district, to the sub-centers, population density, land price, urban block area and cost of public transition in Yazd. Multiple regression analysis is used as the research method. Simple sampling method is used To select districts. So, at first, six district selected (Fahadan and Sheikhdad as central districts; Sare’dorah and Maskan’o’shahrsazi as middle districts; Azadshahr and Safa’eeye as outer and developing districts). After selecting the sample districts, the sample size from each settlement had to be identified. Stratified random sampling (Proportional allocation) is used to do this process and totally, 72 sample extract and study for this research. Construction density is seen as a dependent variable (Because the principle is that wherever physical development has occurred, the construction density increases) and the others as independent variables of the analysis. According to the results of the analysis, construction density of the neighborhoods is a function of distance to central business district, distance to the sub-centers, urban block area and price of land (with negative correlation coefficient) and population density (with positive correlation coefficient). There is no relationship between the construction density and cost of public transition. So, it can be interpreted that construction density increases by reducing the distance to the city center. This fact lonely explains the spread of physical structure in city of Yazd. Also, the negative correlation coefficient between construction density and distance to the sub-centers shows the distributing of compact districts in sprawl urban areas. The positive correlation coefficient between construction density and population density shows that somewhere population density increases, the construction density increases too. As considering that the average area of city block from the center to the periphery increases in city of Yazd, it can be said that the construction density decreases from center to periphery. The negative correlation coefficient between construction density and land price is one of the Interesting and distinctive results in this study. This finding shows that if the city spreads in periphery lands, the land prices in this area will increased. On the other hand, land demand in the periphery of Yazd is promoting and Residents of the city of Yazd, in contrast with intensive development in the past time, are now more willingness to live in detached houses. It is the sign of the increasing occurrence of urban sprawl in Yazd. Manuscript profile -

Various models have been proposed for understanding the city shape and its scattering measurement. Material and Methods: This work aims at calculating Tehran urban sprawl in various decades using different models including temporal analysis of urban density, quartile distribution, degree-balanced distribution, degree of aggregation and Holdern model, and its impact examines on nearby farms. Results: Findings of this work show that Tehran is shifting from concentration and gradual growth to excessive urban sprawl and rapid and uncontrolled growth. In The following, using satellite images of the years 1357 and 1385 we examines the rate of change of land use especially the quality and quantity of changes of farmland to urban uses with using ArcGIS software. The image has converted to maps through visual processing or visual interpretation. At the end with map have obtained with using compilation and synthesis method that can show to how land use changes during the period (28 years). Discussion and Conclusions: The results of research in this section indicate that the total agricultural land in study area in 1979 was about 38952 hectares that Half of which have been eliminated in the course of 28 years 1996- 2006 and have decreased directly or indirectly through urban development and reached 19.4 thousand hectares in 2006. If the growth and development of the city continues as sprawl distribution. The same amount of land will be destroyed in the future development. Manuscript profile -

The software utilized was SPSS, GIS and EXCELL. Because of the data sprawl, the research indicators were collected by a questionnaire using the detailed plan of 2016, the statistics center and field collection. Based on the theoretical foundations of the research, 4 main indicators were studied: population change, participation, security and quality of life. The statistical population consisted citizens of Yazd who were over 15 years old. According to the Cochran's formula, the sample size was 400 people; and sampling was done by simple random sampling method in proportion to the population of the neighborhoods by stratified random sampling in the neighborhoods. Overall Cronbach’s alpha of the questionnaire was 0.893. The results showed a high correlation between quality of life index and social sustainability. Quality of life, security, participation indicators with correlation coefficients of 0.948, 0.721 and 0.673, respectively, were the most effective; and they had a significant relationship with social sustainability. Migration index was -0.217, therefore it had no significant relationship with social sustainability of Yazd neighborhoods. Among the neighborhoods, Safayyeh, Imam Shahr and Kooy-e Taleghani were the most sustainable and Eish Abad, Kheir Abad and Airport were the most unsustainable neighborhoods in terms of the social dimension.

Urban sprawl is one of the city growth phases that have entered to urbanism literature from the second half of the twentieth century and nowadays it is one of the most important debates in the world. This study deals with urban sprawl measurement in Mashhad city. To measure this phenomenon based on F’ANP model, sprawl indicators have measured for 43 districts in Mashhad. The model results show that the five factors centering, density, mix use, acting space and accessibility influence the rate of sprawl in different districts of the city. The results show that the districts near to CBD have the least rate of sprawl. As the distance from the CBD increase, the sprawl intensifies, so that sprawl has occurred the most in the East, North East, North West and in the South. As one of the main reason, we can point to formation of big city blocks with industrial and military land uses and informal settlements. Manuscript profile -

Zahedan, during its 100 year life, has developed in an unbalanced way and has faced a quick development. The 32.5 time development of its population and 34 time development of its width indicate this issue compared to the first census in such a way that the development of this city has been in the horizontal direction and the continuous development of urban constructions have caused the ugly development of the city. Accordingly, in the present study, the correlation between the population and the amount of development and urban sprawl is investigated in Zahedan city using Shannon's and Holden's Entropy Models and Floor Area Ratio (FAR). The findings of the research indicate that according to Holden's model, Zahedan has been suffering the ugly urban development (sprawl) during the period of conducting the study. The entropy coefficient scores indicate the sprawl of Zahedan. Regarding the development of the value gap due to horizontal development and urban sprawl, theSmart and Compact City model is considered as a desired one for future expansion of Zahedan.

Excessive population growth and quick increase of the number of vehicles in our country and on the other hand, fixed physical structure and quality of pathways and streets, and the transformation states, leads to vehicle compressibility in communicative routes. Kerman as one of the metropolises in Iran is not an exception. Since one of main traffic problems of Kerman is related to cultural issue for encouraging people to use Foot Bridge, the main objective of this research is to study the existing bridge’s condition and analyze its efficiency. In an analytical and descriptive research through testing the null hypothesis , the quantitative results of which was verified by the collected qualitative data, the researcher attempted to determine the perception of the citizens of the efficiency of the existing footbridges. The findings revealed that citizens believes that existing structure of footbridge can't be helpful in reducing the traffic density in communicative routes in Kerman. Manuscript profile -

Across the last three decades, the outcome and effects of imbalance interaction of Tehran in relation to its peripherals ahave resulted in bioenvironmental problems and rapid changes in economical function of villages, transformation of the valuable agricultural land from production form and unsustainable agriculture in the villages surrounding Tehran metropolitan. Thus, this study aimed to explain manner and the rate of agricultural land use changes and unsustainable agriculture and its relation to rural capacities and concentrated settlement policies in the villages surrounding Tehran metropolitan. The results of this study showed that a positive significant correlation was found between variables of rural capacity (number of services and structure), concentrated policies (rate of distributed loan and number of executed construction activities and rate of change in agricultural land uses. Also, a negative significant correlation was found between distance from Tehran metropolitan and cities surrounding it and rate of changes in agricultural land uses. According to this study, the most effective factors in changes of agricultural land uses and unsustainable agriculture were uneven development and metropolitan sprawl. Manuscript profile -

In order to measure and study the urban sprawl, first land use maps were created by using Landsat satellite images in four classes (urban and built areas, water and paddy areas, forests and agricultural lands as well as gardens) .They, also, used spatial metrics (Class Area, Number of Patch, Patch Density, Total Edge, Edge Density, Mean Shape Index, Area Weighted Mean Shape Index, Euclidean Nearest-Neighbor Distance, Proximity Index, Aggregation Index) in two levels of class and landscape to calculate the Rasht city Urban sprawl surface via FRAGSTATS software. The results of the research show that urban areas have grown increasingly and several urban plots have emerged. Along with this growth, agricultural land and paddy fields have lost their spatial cohesion and integrity and have turned into considerable number of plots. The coefficient of 103% increase in urban class over a period of 26 years (1993-2019) indicates the rapid change of spatial dynamics of the city into physical dispersion, which, in turn, is generally associated with land use change, land cover change and destruction of natural and terrestrial resources outside and around the city.

One of the problems is horizontal and immethodical expansion that has caused traffic, more use of energy, more environmental pollution and social isolation. If urban management is trying to control and reduce the urban problems to present urban expansion models, then it should reconsider urban planning methods and create efficient models in urban environments.This essay is aimed to present modern and efficient methods of urban structures by clarifying the infill development model and urban high-rise construction method and is also trying to answer the question that: " Can high-rise construction be an acceptable method of urban endogenous development in Bojnurd as a medium-sized city? " by conducting library and field studies and a practical research method.Bojnourd is a medium-sized city in the northeast of the country.The city has an area of more than 3,000 hectares and a population of about 250,000. The results show that Bojnurd expansion has faced urban sprawl over the past 20 years and about 70 hectares have been added to the city area while the available area of the city has the endogenous development potential and standard compact construction; and checking the population compaction, land value and urban pathways capacity and the questionnaire outcomes done by urban managers show that in some peripheral areas of the city, there is the potential of high-rise construction up to 6 floors in order to prevent the immethodical city expansion.

In this regard, the present study has considered the physical development characteristics of Khorram Abad city in terms of quality of physical development of the city by using indicators such as land use compatibility and incompatibility, land use mixture index as well as quantitative indices determining he indigenous development of city such as population density changes, the ratio of area growth to population, the number of licenses issued, and the quality and age of buildings in old texture. The research method is descriptive-analytical through library (documentary) and field studies. The results of this study show that, despite the fact that the city of Khorram Abad has internal development potentials, but like other cities in our country, it has experienced sprawl growth in recent decades. Investigation of various indicators showed that the city did not follow the indigenous development policy in its physical-spatial development. In addition, less attention has been paid to the compatibility and incompatibility of neighboring land uses and to the mixing of different land uses within the urban context. Considering the developmental capacities in the old textures of Khorram Abad city, construction in these textures, by implementing incentives policies and increasing floor area ratio, is the best way to prevent uncontrolled growth of the city, reduce costs and urban development issues Manuscript profile -

Urban sprawl in Tehran has led to several challenges in achieving sustainable development. A spatial analysis on urban sprawl in traffic area zones (TAZ) of Tehran has been investigated for the past two decades (2001-2020) using the Weighted Urban Proliferation (WUP) method. Then, the minimum access distance between each pair of TAZ-hospital has been calculated using Network Analysis and the relation between sprawl determinants and accessibility has been investigated. Finally, the Lorenz curves and Gini coefficients have been calculated. Results show that the sprawl level has decreased significantly in Tehran over the past two decades. Consequently, because of the direct relationship between dispersion and access distance, the maximum distance to the nearest hospitals has been reduced about 3 kilometers. However, the calculated Gini coefficients show a 10% growth over the study period; in a way that, in 2001, 90% of hospital opportunities were distributed among 29% of population, while in 2020 the same share of opportunities are distributed among only 7% of population. Results indicate that urban sprawl reduction can only increase accessibility standards and promoting equity of accessibility requires proper attention and management of socio-economic variables along with urban sprawl.

The field research method and library documentation were used for the collection of information,and the Excel application was used for drawing the graphs and doing the calculations while the GIS and Autocad applications were used for drawing the maps.The results of the research indicate that the Anzali Port is the only urban center in the town which attracts the immigratingpopulation,including the adjacent villages and cities.During the recent half century,this process has decreased the city’s population and its lands and the city inevitably develops toward the lands of the adjacent villages. Throughout this process, the Anzali Port has merged four villages in its proximity including Sousar, Navir, Shahvar and Koulivar while the Bashman and Talebabad villages which are located in the peripheries of the city are not exceptions to this rule as the majority of their lands have undergone a change in used and turned into urban constructions.

From the early twentieth century, has increased. This trend raised the number and size of cities in these countries and led to urbanization and. So cities were encountered with specific problems. Cities Physical development and urban population growth and subsequently changes in physical and spatial development of cities to become a problem or issue in recent decades. And attention to urban issues - particularly the physical issues - in the form of a scientific framework is the importance and necessary. Babolsar city with having a natural, tourism, academic attractions and ... has grown as one of the main poles of attraction of population in the Mazandaran province, in recent years. This trend of population growth and Entry Immigration and tourism led to the construction without plan and large change in the space - physical structure of city and its development in the coastal strip and surrounding agricultural land. Research Methodology Methodology depends on the purpose and nature of its research and administrative facilities. * Responsible Author: urban_planner65@yahoo.com Thus, the approach of this research is field, library and descriptive - analytical. Data and information needed to research has been taken from field and processed. So, after select the topic, at first with examining documents and library data bank Online, physical development and population trends of Babolsar in different periods of history was determined. After collecting the required data, with relying on the information obtained, the physical development and population trends of Babolsar in different periods of history was determined. After collecting the required data with relying on the information, obtained the physical development and expansion of Babolsar city with use of Shannon`s entropy and holder models. But the main research approach has been based on descriptive- analytical methods. Results Today, knowledge of space form of city can be one of the most important affecting factors in success rate of urban planners to meet the needs of present and future, In this paper have been helped two models: Shannon`s entropy model to analyze the physical development of Babolsar City in 1379 and 1389 which are respectively 11 and 22 quarters (Map 3), Shannon`s entropy model: we use this model to analyze the Ugly urban growth phenomenon. The overall structure of this model is as follows: The results found that amount of entropy in Babolsar city was 20166 / 2 in 1379. While the maximum value is Ln (11) = 2 / 3978 is Can be mention to being close the amount of entropy to maximum amount (2 / 3978). This issue represents dispersed (sprawl) the physical expansion of the city. 11 neighborhoods of the city were separated into 22 neighborhoods in 1389. The estimated amount of entropy is calculated equal to 94214 / 2, while the maximum value isLn (11) = 3 / 0910 that it shows, the physical expansion of the city, was scattered over the past ten years. Holdern model: Results of the Holdern model about the Babolsar city shows that within the 1385-1335 years About 60 percent of physical growth, population growth related to population growth and 40 percent of physical growth was related to horizontal growth and urban sprawl that it`s result was decrease density Gross population and increase of Per capita net urban land and eventually ugly Horizontal spread (sprawl) of Babolsar city. Conclusion In this paper has been discussed and analyzed pattern of physical development of city in different periods and with use of related models. the amount of Shannon`s entropy of Babolsar City showed diffuse growth (sprawl) in 1379 and 1389 that led to destruction of part of quality agricultural land. In survey of appropriateness of the size of the city’s development with population during the decade (1385-1335) with Holdern model came to the conclusion that About 60 percent of the city expansion was consistent with population growth and 40 percent of physical expansion, was due to Ugly urban growth and inharmonious (sprawl) of city. This is the result of uncontrolled urban growth And not having a written plan for the physical development of city. Population growth and limitless expansion of the nearby city of Babolsar, Cause excessive pressure on water resources and other infrastructure, the destruction of good agricultural land around the city and has many other issues. We found out that something's helps city to prevent uncontrolled physical expansion; can be developed within the context of the city, expansion the culture of vertical wings the city, and eventually Providing facilities in the villages to prevent migration of villagers to the city's.
