Among the many factors influencing the wheat production, environmental conditions and climate are the most important variables that need to be scrutinized. According to the talents and capacities of wheat production in the city of Shush, according to the 12 year comprehensive review of climatic and environmental factors were identified. Then based on Boolean logic in GIS environment between any of the environmental and climatic parameters were studied in wheat. Finally, wheat prone areas were identified in the city of Shush.The results indicate that the city of Wheat cultivation, favorable conditions and has the talent is, But culture is made of wheat and wheat growing areas of the north and northeast of the city, the best place for you is.

Ilam province, located in the west of Iran, owning natural, cultural attractions and capabilities on attracting tourists, but existing capabilities and potentials have not been used properly. In order to facilitate tourism, suitable times and places shall be determined for tourists` presence in the region. One of crucial needs of tourists is considering regional status and suitable times of tourism. In this research, TCI regional tourism index as well as data from 5 synoptic stations of the province was used to evaluate tourism regional and regional tourism conditions of Ilam province. Thus, necessary statistics of seven regional parameters were exploited from 5 synoptic stations in a 14-year old period monthly. (1997-2010). A database was formed after statistics exploitation then, they were processed using TCI index. Then, suitable times and places for tourists appearance determined through moderating by GIS software, generating point data to surface ones and mixing the maps. The results of the research indicate that the province`s tourism index owns many varieties, i.e. north areas of the province bears suitable conditions in warm season of year while the condition changes in cold seasons but southern areas of the province have suitable status while north areas bear unsuitable conditions.

Urbanization and the specific problems of urbanization, more than ever Attention to the design of effective strategies to optimize the lives of citizens is essential. In The aim of this study was to investigate barriers Quad change (attitudinal barriers - knowledge, norms - behavioral, communication, institutional) of the Comprehensive Plan to the Strategic Plan in Iran.method is qualitative methods. Sampling was targeted was available. In the qualitative phase, semi-structured interviews, Barriers were identified. The population in the qualitative phase consisted of 5 professors and consultants That in the master plan and strategic planning activities or the activities they have been. The quantitative analytical research. In this section, rankings and barriers identified were examined. The results show that the most important barrier to the knowledge attitude barrier to urban planning system in Iran. This makes the Given the importance of attitudinal factors - knowledge, By removing barriers to the index, you must first attitude and knowledge of the two major categories Conservative and the resistance is strengthened, If these two issues be addressed And the gap between the two is Surely the way to achieve ideal conditions in terms of other indicators to achieve the strategic approach will be facilitated.

Rapid urban growth and physical development have led to declining environmental quality of life, especially in informal neighborhoods. The purpose of this study is the satisfaction of the quality of life of residents of informal settlements in the city of Babul. The method used in this research is a descriptive survey. This research has been done according to the method on the field and library that in the field . The population of Babul informal settlements are include areas Moziraj, Kathy, Hafttan and Sadat neighborhood. The sample size according to Cochran formula was obtained of 282 people. In this study, using a T-test and chi-square tests were a way to satisfaction with the quality of life of residents of informal settlements Babul examined in 5 areas of housing, leisure, travel, health and safety and the environment. The results indicate that the satisfaction of local residents about the quality of the living environment, with an average 2.8 (with no middle 3) the unfavorable evaluation. In this regard the satisfaction of the areas of recreation and leisure, housing and the environment and health is below average and the areas of security and travel a little more than the average.

Drainage density is one of the parameters that can be considered as an indicator of erosion rate. This study analysed the relation between drainage density and soil erosion in five watersheds in Iran. The drainage density was measured using satellite images, aerial photos, and topographic maps by Geographic Information Systems (GIS) technologies. MPSIAC model was employed in a GIS environment to create soil erosion maps using data from meteorological stations, soil surveys, topographic maps, satellite images and results of other relevant studies. Then the correlation between drainage density and erosion rate was measured. T.The results indicate that the relationship between these two factors improved when the types of sheet erosion, mechanical erosion and mass erosion was ignored because these types of erosion were not mainly influenced by the power of runoff. There was a high correlation between drainage density and erosion in most of the watersheds. Finally a significant relationship was seen between drainage density and erosion in all watersheds. Based on the results obtained, the present method for distinguishing soil erosion was effective and can be used for operational erosion monitoring in other watersheds with the same climate characteristics in Iran.

Water quality must be tested before it can be used for agricultural purposes since difficulties might arise in terms of increased soil salinity, decreased soil permeability, and decreased water absorption by plant roots; leading to reduced agricultural productivity. The aim of this study was to used Arc GIS (for graphical representation of the qualitative parameter's variations) as well as the conventional diagrams and parameters used for agricultural water quality classification for studying and zoning agricultural water quality in Kelachai Region in Iran. Results showed that the quality of all samples was classified as excellent for agricultural purposes in terms of the following parameters and diagrams: MR, SAR, Na%, RSC, pH, KR , CR, PS (just for w6 and w8), Wilcox diagram (except for w5), Gordon diagram just w7, w14, and w15, and Doneen diagram(except for w13,w14,w15) . In terms of correlation, the most and least correlations were found to exist between Na% and KR, and EC and PI parameters respectively.

Veneered surfaces, roofs of buildings, streets and the like in urban areas as a barrier against the infiltration of rainwater into the soil and groundwater recharge.They cause more of rainfall to surface runoff and floodsto be converted. Combined method influence, storage and transmission of Atlantis, as the most urban runoff management approach, including implementation of a network of underground ducts, using Atlantis materials and execution of drainage layers on it and store water collected from the network. In this way, the possibility of penetration, transfer and storage provided and benefit levels increased urban streets as well as the transfer and accumulation of contamination is prevented. Town sajadieh located in the lower elevations of the highway and besat shahrzad and street in the south and west causes waterlogging town streets in the rain times. The present study has a descriptive, analytical approach and to investigate the role drainage plate networks, channel and ecological reservoir as the new approach in connection with control and management of surface runoff in town sajadieh Tehran.
