ارزیابی سطح توسعۀ پایدار در محله‌های باغ‌شهر تاریخی میبد

Extended Abstract
Introduction
The economical - social and bio - textual system changes in favor of cities has transformed urban sustainable development into an efficient and important paradigm in urban management affairs. It is necessary to draw cities future plan. Hence, inequalities between regions and neighborhoods are of special importance. Meanwhile, inter - regional and local inequities have particular importance. Meybod is remained everlasting on the basis of its valuable past. The existence of several subterranean canals had been effective in spatial order of this city and affected its path on the urban network. Old cores of city had been affected by the agent of water and subterranean canals. Meybod City from the viewpoint of community structure and unhealthy competitions for the acquisition of facilities and urban substructures has challenged the spatial organization of communities. Consequently, the irregular use of the land around the city caused imbalanced growth  and confronted the life with problems and difficulties for future generations. In this article, we try to emphasize the neighborhood inequalities in Meybod city.
Methodology
This is an application - development research with descriptive – analytic examination method. The geographical range of research is Meybod city, with 18 separate urban sections. The data required for this study is obtained from literary sources, results of population and housing census data of 2006. By SPSS software, 49 indicators were extracted and sign test (wilcoxon) has identified the place of Meybod city among the urban areas of the country. Up to 33 indicators are identified and ranked for factor analysis standard test and composite index of human development of stable level of regions. Then, the dispersion coefficient model has been applied to examine rates of inequities among locations to provide a strategy. Indicators statistics as sustainable development indices are selected and divided into stable and unstable indicators according to the positive and negative nature of some indicators.
Results and discussion   
The first step in evaluation development of Meybod city is comparison with national indicators. In this research using indicators, in a variety of social, economic, biological and physical aspects and with 95 percent confidence interval, it can be said that situation of the selected indicators of the city were better than the national indicators. In inner – city, one of the appropriate criteria for identifying facilities and lack of locations of a city is classification of them according to various  economic, social,  physical, environmental and other indicators. Therefore, in this research we divide the Meybod urban locations into five groups: stable (ideal stable development), strong stable development (positive), semi-permanent, weak stable, and unstable development. The importance of this classification is that knowing the stability of the location can show the level of living the population of a region and also  present the plans and programs for decrease in the shortage and deprivations. However, since it is possible some locations, from the viewpoint of health, house and factors of culture have good condition and they may yet be unstable in the viewpoint of economic, physical and environment status or vice versa. Hence, it seems necessary to distinguish stability of different locations using the combination indicators that enable the level of living and material and cultural comfort of people in each region. We try to address the stability of Meybod city according to the 33  stability indicators by factor analysis in 6 factors covering 75 percent of variance. Then, we calculated the dispersion coefficient for each of the factors and analyzed rate of stable and unstable. Finally, ranking of locations in compilation of index can be used of the standard scores and indicators of Morris. Human development indicators (HDI) are also used to  determine the rate of stability and instability of interest locations.
Conclusion
 According to the results of this research, the small town called Imam Jaafarsadegh and the old districts of Firuz Abad have been identified as the most stable and instable regions in Meybod city, respectively. The district (11.1) as the sole stable area in this city has been constructed totally compatible with the principles of sustainable urban development. Districts (7.1, 13, and 14) on the other hand have been recognized as instable districts in the city. Among the striking ecological and pathological features of the instable districts of Meybod city, we can see lack of social integrity, destruction of gardens and highly productive agricultural lands, the drastic shortage of services, installation, equipment and facilities in the town and etc. The semi-stable districts are located in such a way as to develop the primary cores of the districts in the city. These districts were founded as a result of the physical development of the city in the past years. The most striking characteristics of this part of districts are high housing per capita, strong and standard houses, much open space establishment of educational, sports, commercial and trade services. The figures indicate that stable development in the fields of social and spatial equality of inter-generational and even inter-generational justice has failed to materialize the Meybod city.
