Such concepts as Green city, Ecological city, living city and Environmental city are referred to as urban sustainable development. Sustainable city is also a new approach to achieve urban sustainable development that was introduced by Appleyard in Livable Streets book. According to growth of urbanization all over the world, especially in developing countries such as Iran, it is necessary to study the dimensions of these approaches to create a viable city. The purpose of this paper is to evaluate urban livability indices in eight districts of Ahvaz city. The study is based on applied research and its methodology is descriptive-analytical. The statistical population includes 1095389 inhabitants in eight districts of Ahvaz city and by using of Cochran formula ,384 persons was estimated as sample size. At first, indicators of livable city were identified by using of documentary and library sources, then the required information of Ahvaz’s eight districts was collected with questionnaire tool. Finally, Ahvaz’s eight districts were evaluated and ranked by Shannon entropy and VIKOR decision making (VIKOR) methods. The results show that Ahvaz’s No.3 and No.5 districts have severally the highest and lowest livability than others. To clarify the status of each area, all of them were categorized into three spectra. Overall, three, one and four areas of the city had desirable, area semi-desirable and undesirable situation, respectively. Therefore, balanced planning between areas and considering undesirable areas should be included in the tasks of the authorities.In recent years, various concepts of sustainable development paradigm have been proposed that most of it consists of geographical branches.

In addition, urban structure planning requires the use of localized data at the appropriate scale. Choicing of the optimal scale in studies is one of the principles that can make the results of studies more accurate and practical. The purpose of this study is investigating the effect of scale on urban spatial and environmental studies of 1 and 3-district in Tehran. The present research approach describes the effects of scale on urban land scape by using ecological land scape pattern and satellite images in meso-scale (Landsat satellite) and micro-scale (Quickbird satellite). Comparing the results of land scape quantification in the meso and micro scales in 1 and 3-district in Tehran, indicates the difference in the results. In the first scale 1747 green patches and in the second scale, 36516 green patches were distinguished, which both of them are used. Also some differences are in the size and density of the edge as well as the shape of the patches in the two study scales. In addition, the results show that the characteristics of patches in micro-scale of 1 and 3-district in Tehran are closer to the natural state of green space of these deistricts and more applicable in urban and local planning but they arrangements are less. This less order has nothing to do with the destruction of such space. The importance of arrangement of patches is important in regional studies. At this level, mid-scale images survey are recommended. In general, by guiding studies based on the principles of scale, the uncertainty of the results can be minimized and the quality of decisions will be improved.Understanding the problems of cities and also their physical pattern and form at different scales are very important.
