        Background and purpose: Power plants have pollution of water, air, soil, and their voice and considerable damages to the surrounding environment enters. But also with the growth of population and industry,.... the demand for energy, especially electricity consumption has been growing in recent years But also with the growth of population and industry, the demand for energy, especially electricity consumption has been growing in recent years And the fact that the electrical energy supply required is often require build new stations and treatment plants social consequences, economic, political, environmental and many.Research and Method: This paper identifies important factors in determining a suitable location for the construction of gas power plant in the province of Gilan, and the effectiveness of each of these factors, by using fuzzy and Boolean and software to GIS, integrating layers spatial data do and potential locations for the construction of gas power plants were identified. Findings: The results showed With regard to the integration of different data layers and limitations, about 90 percent of Gilan province as a constraint areas were determined for power plant   And the other 10 percent, 5 percent favorable weight and 5 percent is weight the semi- favorable and unfavorable.Results: Finally, Compared with five operator fuzzy model, fuzzy Product function better than it looked.

        The Rivers are more important sources of surface water and fresh water in urban, agricultural and industrial. The aim of this study is to evaluate effects of pollutant sources on the water quality of river Zayandehroud using Geographic information systems (GIS). In this study, physicochemical data (Discharge, Hardness, Cl, EC, pH), (October 2010 to May 2011) were studied in 7 stations of Zayandehroud. A land use map of the surrounding environment was then investigated with a buffer 0f 10 km from center of the river. Considering the location of monitoring stations the key factors, distance to industrial unit and land use percentage within the station buffet were calculated using GIS. Data moves to SPSS®19 for further statistical analysis. The results show that, at 451682.3 hectares of around buffer the river consisted; 40.9% agricultural and 8.1% urban development. We also found that the physicochemical parameters have a direct with the increase agricultural area around each station relationship. Also located industries in the area of Polkalleh to Chum stations such as south Isfahan refinery, have a significant relationship with water quality factors discussed in this study. So considering the protection importance of the Zayandehroud river, applying appropriate management on this river is essential, especially in the areas after the city. Implementation of appropriate treatment system for industrial wastewater, advised to farmers in the proper use of chemical fertilizers can be the appropriate solution. Manuscript profile

        In recent decades, along with urbanization, various models have been used to urban growth prediction. In this regard, Urban models based on the automata technique have emerged under the paradigm of a self-organizing system, with cellular automata (CA) being the simplest but most popular in action What happens to each grid cell is defined by a transition rule or transition rules.If the transition rule requires that the state of a grid cell is only dependent on its state at a previous time step, such a model is called a Markov model, and is not considered a CA model. Cellular automata models have one additional feature: the transition rules operate on cells based on the local neighborhood of those cells. In this research, the spatial expansion of Maragheh city was simulated using Cellular automata- Markov chain hybrid model. Satellite images (Landsat) were used for land cover mapping, urban growth monitoring, and modeling land cover changes. Results represent high efficiency of Cellular automata- Markov chain in the urban spatial growth simulation. In the past three decades,development trend of Maragheh city has been more towards barren lands.According to the output of the model,this trend will continue over the next 17 years. So that, the city will be expended due to the transition of barren lands cells state to urban cells state,and 774 hectares from surrounding barren lands will be converted to urban lands. However, with continue of the previous trend, nearly 417 hectares of good agricultural lands will also change to urban lands. Manuscript profile

        Parking is one of the most important urban infrastructures that have a major role in reducing Marginal Park and trafficflow.Nowadays in the megacities due to land and space constraints with creation public parkingapply optimal management to increase services of large content of vehicles,Public parking when can be sufficiently aware effective that have optimal geospatial site selection. Now, Rasht city and transport network its, is encountered with main problem the lack of parking for residential users and other usersand perform the work, regardless of the land use has caused that this problem will occur slowly as a urban problems.This problem in crowded places,that urban multi land use, especially have administrative - business and leisure land usemanifests itself in the form of a serious.since Rasht haven't highway network.in addition to the regional transit it is open to shipping through other parts of the province and non-optimal positioning of the existing parking is on of the main problems in the city.In this study, for optimal site selection of public parkingfor greater efficiency the study area.Initially, was preliminary study to identify influencing factors for optimal Parking site selection, Using the Analytic Hierarchy Process (AHP)Weighting factors were takenand Finally, using a geographic information system (GIS)were proposed appropriate zones for the construction of public parking.
