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.

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.
