The purpose of this research is measuring and evaluating urban livability components using environmental indicators approach based on MCDM techniques in triple neighborhoods of Ahwaz metropolis. This research is descriptive-analytic in terms of method and nature, and in terms of purpose it is an applied research. Also, data collection and required data for research were carried out in two ways of documentary and survey. Then, the data were analyzed in the first stage by SPSS software, so that the reliability of the research tool was tested by Cronbach's alpha, which is 0.882, indicating a high level of reliability of the questionnaire, and using the ANOVA test and the Tukey and Scheffe test. Urban livability status was measured using environmental sub-indicators. Subsequently, it was entered in the EXCEL software environment and using the multi-criteria decision making models of VIKOR, ELECTRE, SAW, and the caplend integration model. Three areas were analyzed in terms of urban livability with emphasis on environmental indicators ranking and prioritizing them. The final results of the research showed that based on the capland model, the Kianpars neighborhood has the highest priority as the environmental indicator of urban livability, and then Golestan and Sepidar neighborhoods were placed in the next priorities. Also, the integration of sub-indices of neighborhoods and the proportional coefficient of the three neighborhoods in Copland integration model showed that the Kianpars neighborhood in terms of urban livability with an environmental index approach in the suitable conditions, the Golestan neighborhood is in some degree suitable and the Sepidar neighborhood is in not suitable condition.

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.

The main objective of this research, review and analysis in the balance of the city by 65 to 85. The collected data used in Excel and Spss program, after that studied in the index of urban concentration (Mehta), the rank - size, entropy coefficient, coefficient of variation have been studied. Population of Khuzestan province the population of this research content urban areas in periods of 65 to 1385. Data collected & analysed from amarnameh websites related to urban areas in Khuzestan province had a population census. This research is theoretical and its Method is survey - analysis. Few of The results of this study, are: the problem of balance in Khuzestan province in the urban hierarchy is still one of the characteristics typical of urban systems. because the First city of Ahvaz, the provincial urban hierarchy from the rank - size and discrepancies did not comply, imbalance and alienation in the urban system, it is clear. In order to achieve a balanced urban systems require policy and planning in the military establishment developed, consisting of small and middle cities and urbanization in the context of national strategies. That unity and territorial integrity to be followed by a space.
