One of the essential functions in geografialy urban studies by using of spatial and temporal data is urban growth analysis. In this context, urban horizontal expansion can be measured by statistical indicator. The main objective of this article is monitoring of growth of 9 urban areas, quantifying the degree of urban free growth, the degree of uncontrolled urban expansion, and the benefits of urban growth for a period of years 85-91, in the Shiraz city. To achieve this goal, the K-Score Pearson test is used for measuring the degree of city expansion, and Shannon Entropy is used for the degree of city sprawl, and finally the degree of urban growth was surveyed. These dimensions were measured for both the period of 85-91 and 9areas of Shiraz. Results show that the degree of freedom for a period of time is high. In the period of 88-89 observed growth of construction was less than expected. In area 1 the observed growth is equal to the expected growth. By considering the whole city, the general Shannon Entropy also shows concentration. In the end, the analysis of city benefits indicates that Shiraz has experienced a favorable positive city growth in all regions.

This study aims to On the Relationship Between Citizens' Satisfaction of the Municipal's Performance and the Urban Environment's Sustainability Indexes in Dezful. Methodology of this study is descriptive-survey and the data are collected through a questionnaire with a sample size of 322 people in three different districts in Dezful. The SPSS software was used for data. The t-test results show that the degree of citizens' satisfaction of the municipal's performance is average to low. In this study, the independent variables (age, sex, education …) were supposed to have a priority over the dependent variable (satisfaction). According to the linear regression test, there was a marked difference between the socio-economic status of the citizens and the amount of their satisfaction with municipal performance. The results obtained from a variance analysis also showed that there was a significant difference between age and the citizens’ satisfaction while the Man-witni test showed that there was no difference between sex and the amount of satisfaction. Finally Pearson correlation coefficient indicates that strong and direct relationship between satisfactions and protects the environmental.

Unfavorable spatial distribution of schools in the Ahvaz city causees problems such as long distance and time of access to schools, lack of proper educational facilities and incompatibility of educational uses with other land uses that has negative effects. The aim of this study is to analyze spatial pattern of educational uses and determine the optimal pattern of spatial distribution of high school of district 3 in Ahvaz city. This study is a descriptive - analytic. Required data (map layers) has been obtained using satellite imagery, urban land-use maps and detailed maps of Ahvaz. Analysis and standardization of the layers was performed using ArcGis software. Layers are weighted using the analytic hierarchy process AHP. Final integration layer in overlay method was performed using the Raster Calculator option. The results showed that six school from 17 one in the study area (Tondguyan - Jannat - Farhangian - Hekmat – Ferdowsi - Azadegan) are in very convenient location domain for optimal pattern of spatial distribution of school. Results also showed that Mouod high school is located in a very inappropriate spatial state.

The aim of this study had been evaluated the qualitative and quantitative characteristics of green space in 18,19 and 21 district of Tehran Municipality. So using satellite image of Land sat 5 in 1991, 2000 and2010 in areas of study, green space density maps is provided by NDVI index. To predict the future trend of green space of the Markov chain model was used, also. The results show that most of the changing in land use related to green spaces and conversion of them to urban land use. Based on results argued that the development of urbanization in case study, caused to loss of green space and agricultural land and least likely has been related to change in other land uses. The results of probability of changes in land uses and classification of NDVI has determined that 12.5 hectares has increased the urban areas. Therefor it caused to reduction of agricultural and green areas in case study. Also, in this research has used strategic management technique and SWOT matrix for evaluating of internal &external effecting factors. According to obtained score from internal(2.89) & external(3.23) factors in such circumstances, districts should to adopt strategies of “power-chance” or SO. A review of detailed plan and legal requirement is one recommended strategies.

Today, in the all the cities around the world, in particular in the metropolitans, the crimes and offenses are dramatically increasing that has concerned both citizens and urban authorities.It seems the kind of relationship between the land use and its distribution throughout the city, including have increased the social vulnerability and crimes in the cities. Ahvaz is those of macro cities facing critically with these problems. the present study was to determine the type and extent of urban land use in the formation of spatial patterns of crime in the police station is 15 Ahwaz. This study was a descriptive-analytical. The GIS software was used for data analysis. The results showed an average of crimes in Kampolo the geographical center of the station (Enghelab street) matches. The theft-related charges in the range of distribution and the main foci detected Daghari streets (Lashkar), Hatef (Kian), Bani Hashim and the hospital Ayatollah Karami and West Terminal (Enghelab Square) is. The type and amount of land within the station 15 has an impact on the creation of context, theft crimes. The greatest crime of robbery in the area next to the police station occurred in residential applications. Finally, based on the research findings, recommendations for the management of physical abnormalities and reduced delinquency rate in the limits of the study were presented.

This study aimed to examine the relationship between local-regional climatological data and the concentration of suspended particles in Sanandaj. By the use of the index of suspended particles extracted from the DREAM model, the data reported by the weather station in Sanandaj as well as regional climatological data (meteorological data in Middle East) collected through examining various levels of atmospheric synoptic maps and MODIS satellite images, dust transport systems in Kurdistan province were investigated. Correlation analysis between the average monthly temperature and the index of suspended particles revealed that there was a direct correlation between these two parameters so that during this study, the highest amount of suspended particles belonged to May and July. There was also a negative correlation between the average monthly humidity and the index of suspended particles. The overall results of this study indicated that the region has been faced with a drought in recent years. In fact, lack of rainfall and humidity along with seasonal wind patterns in the Middle East, particularly in the warm seasons of the year, have caused the pollution of suspended particles in Sanandaj.
