  Introduction and Objective:Function is the definitive target of every designing which plays a significant role in relation between efficient and space. The purpose of this research is finding the most significant influenced factor in vitality of urban open space. Method: the methodology is descriptive-analytical and then the case-context method is used in assessing the area of study and finally the assessment and analysis of extracted factors from the literature of the research is presented. The methods are used for gathering data which are, questionnaire and interview and observation.This question is responded by Kolgmorof Smironov test and SPSS software is employed to examine different tests for assessing independent factors and then by using Varimax analysis and multi-factor regression of Kendall’s tau_ b and Spearman’s rho the portion of any of functional factors in the livability of urban open spaces is recognized. Findings: the most effective factor in the livability of Eram park of Hamedan is the practical factor which leaves the most considerable effect on the livability of this urban park due to the viewpoint of Hamedan citizens in general and especially from the standpoint of the Eram urban park users. After this factor there are other factors such as: biological factors, mechanical factors and in the final step systematic factors which have has less effect than the first one on the livability of Eram park of Hamedan. Conclusion: the optimal performance of Eram Park of Hamedan city is a function of the four dimensions of biological, mechanical, and functional system that the most effective one is Functional dimension and its variables (diversity, access, transport, shopping and tourism and security). Thus, according to the correlation coefficient, with the strengthening of this dimension, we can increase the effects of other aspects of dimensions and reinforce vitality.   Manuscript profile

  Background and Objective: The unbridled expansion of cities during the recent decades has gradually led to the decline of their climatic comfort. One of the objectives of this study is to analyze the spatial geometry and structural-spatial patterns of traditional neighborhoods in the cold and dry climate to use the results for optimization of new residential fabrics. This study also aims to investigate the role, plantation pattern and species of the plants in the green spaces of old neighborhoods.Material and Methodology: First the factors that affect climatic comfort were identified by examining expert viewpoints. Then, Ecotect Autodesk software was used to simulate the conditions and analyze the data in three traditional neighborhoods of Hamedan City.Findings: certain measures are required in linear neighborhoods to increase their exposure to sunlight during the cold seasons because they have more shading compared to centrifugal neighborhoods during the cold periods of the year.Discussion and Conclusions: using centrifugal models can help optimize these spaces and improve climatic conditions in them. In addition to preventing the prevailing cold winds from blowing into the neighborhoods from the surrounding environments, the old trees at the center of the neighborhoods selected in this study improve coolness and climatic comfort in these spaces, especially during the hot seasons of the year.

  Background and Objectives: Heavy metals contamination of soil and agricultural products due to the rapid development of industries and improper use of chemical fertilizers and manure on agricultural land have cuased a great concern. The purpose of this study was to investigate the accumulation of heavy metals such as cadmium, lead and zinc in soils and in irrigated wheat and rainfed wheat in some farms in Hamadan city.  Materials and Methods: Soils under cultivation of wheat (irrigated and rainfed) was sampled. Composite soil samples were taken from a depth of 0-20 cm. The location of the sampling stations was recorded by GPS. The composite samples were collected edible sections of the mentioned plants. Absorbent concentrations of heavy metals were extracted using DTPA. The experiments were done independently in the form of a completely randomized design with three replications. Concentrations of heavy metals (lead, zinc and cadmium) were read using an ICP varion 710 in the laboratory of Islamic Azad University of Hamedan. Results: Statistical analysis showed that the mean concentrations of cadmium in the soil of irrigated and rainfed wheat were4/61, 1/60 mg/kg and in the plant of irrigated and rainfed wheat were 2/29, 1/86 mg/kg, with a significant difference of 0/05. The mean concentrations of lead in the soil of irrigated and rainfed wheat were 4/61, 1/60 mg/kg respectively, and in the plant of irrigated and rainfed wheat they were 12/26, 12/84 mg/kg respectively, showing a significant difference of 0/05. The amounts of zinc in the soil of irrigated and rainfed wheat were 32/12, 21/26 mg/kg respectively, and in the plant of irrigated and rainfed wheat they were 13/99, 11/58 mg/kg, showing no significant differences with the the permissable standards. Discussionand conclusions: The result showed the risk indices of over 1 for cadmium and lead, implying that these two elements can be of a greater potential threat to human health in the study area Manuscript profile

  Background and Objective The protection of natural resources, especially land, and their use, has long been considered. It can be said that because land use has undergone many changes over time, these changes have direct and many effects on the ecosystem and the environment and consequently have various consequences, including these consequences that can be used to change land use. The area was affected by the rapid expansion of urbanization and its effects on land-use patterns in the surrounding environment and, finally, land fragmentation in these areas. Accordingly, in many cases, converting land use from its natural state to artificial land use has irreversible consequences. To reduce the consequences, this can be adapted to the land use structure. Land appropriateness refers to matching the capacities of a plot of land and its land use, and the disproportionate allocation of land use and disregard for its changes has many consequences such as socio-economic segregation, environmental depletion, and loss of resources. Decisions in land and resource management should always be guided in a way that does not conflict with the interests of society and the natural environment. In this regard, one of the effective ways to control and minimize the damage and consequences of land use is to adapt its structure so that, based on the characteristics of land resources and their capabilities, the land can be spatially distributed and arranged more rationally. This study aims to identify and zone the appropriateness of land use structure with the existing capabilities in Hamedan and to evaluate the efficiency of the multilayer perceptron neural network method in the field of land use structure optimization in this city.Materials and Methods In this study, to adapt the land use structure in the city of Hamedan, based on the research background and according to the effective criteria in the field of land use structure, various indicators were selected, including 12 land use indicators, slope, average temperature, and average rainfall. Average humidity, average wind speed, geology, soil type, distance from the river, distance from wells, distance from main roads, and vegetation type. Then, using the field visit, the points with user suitability were registered as educational points. After preparing the layers of the mentioned indicators, these layers were standardized in the software environment of the GIS system. In the next step, the multilayer perceptron neural network uses the after-release algorithm by importing layers affecting the optimization of the land use structure as input and using the middle layer of distance. From appropriate points in terms of land use structure, this network was implemented with the structure of 1-10-12 to adapt the land use structure in Hamedan. From 35% of the total image pixels, the distance from the agricultural proportions as training points falls into three categories the first part (70%) for network training, the second part (15%) for stopping calculations when the error is increasing, and the third part (15%) was used for network verification. Finally, the final land suitability map was drawn. The resulting layer had a value between 0 and 1 which was divided into five land suitability classes. In the present study, after identifying the factors affecting the land use structure and adapting its structure, and preparing each of them, the mentioned layers were standardized. Then, using the field visit, the points with appropriate use were recorded as educational points. Thus, the land use structure was adjusted by the multilayer perceptron neural network model with 58 replications. The results of the neural network validation and the resulting output layer indicate the high accuracy of the network in fitting the land use structure so that the square root mean values of error (RMSE), and absolute error (MAE). Correlation coefficient (R2) in the implementation process of the network is equal to 0.19, 0.21, and 0.89, respectively, indicating the network's high accuracy in implementing the optimizing process. Completely inappropriately divided, and the results showed that most of the areas covered some somewhat suitable and perfectly suitable lands with 32.62 and 28.13% of the total area, respectively.Results and Discussion In the present study, after identifying the factors affecting the land use structure and adapting its structure, and preparing each of them, the mentioned layers were standardized.

Completely inappropriately divided, and the results showed that most of the areas covered some somewhat suitable and perfectly suitable lands with 32.62 and 28.13% of the total area, respectively.Conclusion The results of optimizing land use structure in Hamedan show that most of the area is not suitable for agricultural activities in terms of effective factors. In this area, most urban land uses completely barren and uncultivable lands, lands. There are mountainous, rocky, and low-quality pastures, mainly in the western and southwestern areas of Hamedan. Also, in this area, lands that have been relatively suitable in terms of a proportion are quite suitable in terms of 12 factors in the best conditions for agricultural and horticultural activities and are the best place for developing agricultural activities. Thus, to change the land use conditions towards a more appropriate trend while paying attention to integrated urban-rural planning for Hamedan and its surrounding settlements. It is recommended to pay attention to land use planning rural-urban plans and projects because the rapid expansion of Hamedan and its suburban spaces has created numerous challenges in terms of land suitability. In such a way that about 23.1% of the lands are ready to be transformed into unsuitable and completely unsuitable conditions. In addition, 32.62% of land use is subject to change to semi-suitable conditions. Based on what has been said, controlling, supervising, and directing the constructions and preventing the over-horizontal expansion of the city of Hamedan and its surrounding spaces by urban and rural stakeholders (local management) is proposed to rangeland and agricultural lands. The findings of the study also indicated that the highest area of land in this area is related to somewhat suitable and perfectly suitable land and the lowest area belongs to unsuitable and somewhat unsuitable land. Therefore, it can be said that the city of Hamedan is currently in a semi-suitable situation in terms of land suitability, which can have a more favorable trend in the future with proper planning and policies.

  Fair access to urban uses and their optimal use, especially urban green space, is crucial in sustainable development and social justice. Most cities, huge cities, face a shortage of green space and imbalance in this type of use distribution. The spatial distribution of these land uses is considered as one of the important criteria in achieving spatial justice and it seems necessary to study in this field. This study investigates the issuance of green space, emphasizing spatial justice in the 12 districts of Hamadan. This research is applied and based on the descriptive-analytical method. To collect information from different library and field methods, review and compile statistics and information from the detailed plan of Hamadan has been obtained. The results of the network analysis model show that due to the distribution and functional radius of parks in urban areas, population centers do not have fair access to the services of these parks. Considering the population of 525,791 people in the city, for regional parks 58%, district parks 44%, neighborhood parks 85%, and neighborhood parks 6% of the city area are within reach of these parks. According to the results obtained from this study, it is suggested that due to the high share of acquisition and its cost in the construction of urban parks, public lands located in the city should be given priority for green spaces and parks to solve problems related to land acquisition or private ownership. Also, in constructing new urban parks, urban areas that do not have green space should be considered.Extended AbstractIntroduction:      The rapid growth of urban development in previous decades has led to an imbalance in how urban land is used. The rapid growth of cities can be considered one of the biggest environmental threats, the effects of which will be transmitted to the inhabitants of cities, ie humans, and will have a destructive impact on the soul and body of urban humans. Urban parks have a social, economic, and ecological role. With benefits such as treatment of mental illness, a favorable environment for raising children, social integration, and maintaining comfort, these parks are also considered indicators for improving the quality of living space and community development. Fair access to urban uses and their optimal use, especially urban green areas, is critical in sustainable development and social justice. The establishment of urban parks is worth studying to affect the quality of urban life and promote sustainable development and the non-return of capital and profits for municipalities. Most cities, especially large cities, face a lack of green space and imbalances in this type of use distribution.Methodology:        This study aims to investigate the distribution of green space, emphasizing spatial justice in the 12 districts of Hamadan. Methodology: This research is applied and based on the descriptive-analytical method. To collect information from different library and field methods, review and compile statistics and information from the detailed plan of Hamadan has been obtained. The analytical way of this paper is also a network analysis model.Results:     The results of the network analysis model show that due to the distribution and functional radius of parks in urban areas, population centers do not have fair access to the services of these parks. According to the population of 525791 people, the urban parks were first leveled, and then the urban blocks were leveled based on the amount of access to parks and green spaces. The results show that parks with the regional performance of about 216485 residents do not have proper access to regional parks; for district parks, 290335 people are out of access to district park services, parks with neighborhood performance of about 77292 city residents outside the service radius of these parks are. For regional parks, 58%, district parks 44%, neighborhood parks 85%, and neighborhood parks, 6% of the city area are within reach of these parks.Discussion:      According to the results obtained from this study, it is suggested that due to the high share of acquisition and its cost in the construction of urban parks, government lands located in the city should be given priority for green spaces and parks to solve problems related to land acquisition or private ownership. And reduce costs. Also, in constructing new urban parks, urban areas that do not have green space should be considered. Manuscript profile

  Urban Areas’ function as productive center for political and socio-economic development of countries has been faced great challenges in forms of environmental degradation, insecurity, unemployment, lack of housing, traffic congestion and informal settlements. In recent decades, most of metropolitan areas, as a matter of unplanned rural-urban immigration and natural increase of city populations, has been witnessed appearance of informal settlements which can be marked by poverty and malfunction of socio-economic situations. Scrutinizing survey in these settlements shows that level of social sustainability are low in them. The research tries to investigate level of subjective social sustainability in accordance with citizens’ inspirations and conceptions from quality of life perspective. Structural equation modeling is used for evaluation of variables’ relations and analyzing the questionnaires. Results shows that education criteria via two indexes of accessibility to educational services and literacy, hygiene criteria via two indexes of accessibility to hygienic facilities and accessibility to drinking water and sewage facilities, and quality of life criteria via two indexes of accessibility to public transportation and housing quality, are important criteria for social sustainability of the area. Omission of participation criteria from the important ones show that the area needs to be focused by social researchers and practitioners for empowering Manuscript profile

  The main purpose of the study was to investigate the factors affecting the sustainable management of agricultural water in Hamedan. The study population included all wheat farmers possessing irrigated farms in Hamedan city (N=1800). Of these farmers a sample of 317 people has been selected by using randomized multi-stage sampling method. The data were collected through a questionnaire's tool with help of the interview technique. Accuracy of the questions in the questionnaire was face validated by a panel of specialists. To test the reliability of the questionnaires, the questionnaires were first given to 30 farmers and Cronbach's Alpha was calculated (Alpha=0.92) then the questionnaire was finalized. Data analyzing methods such as Multiple Regression and the coefficient of variation (CV= standard deviation /mean) were used in this study. To determine the level of sustainability of the farms Bossel (1999) method proposed for classification and grading the fields was used. The results showed that variables agronomic factors, policy factors and institutional factors were able to explain 34 percent of the dependent variable's changes (sustainable management of agricultural water). According to the results, 95.3 percent of the farmers were categorized into unsustainable group, 4.1 percent into semi-sustainable and only 0.6 percent in sustainable group. Manuscript profile
