Introduction Facing with cities growth problem; planning different surveys follow to real solutions for urban development and one of the most important surveys are sustainable development survey in urban tissues and sectors. This subject move toward non-stability path because of immigration, management, discussions. To achieving society stability, we should more pay attention to low levels. During recent years; focusing on urban tissues, sectors problems and planning to their social and framework improving were located at the first rank. So, Ardebil city sector tissue were ruptured with each other at the result of various factors intervention; and stable sector development plans try to renovate part of damage by reviving sector identity. Planning in sector scale and urban tissue scale are guidelines which they were discussed in current study. Therefore, investigation of Ardebil urban tissues and sectors stability position and presented guidelines to their improving are as inevitable necessities. Study results and presented guidelines by implementation form can reduce urban non-stability and its problem in future and they cause to non-stable sectors residents life level rising. Along to reach of study aim, these questions were adjusted: - First question: What is stability level at Ardebil city current tissues? - Second question: Is stability level different at Ardebil urban tissues? - Third question: what urban tissues have best stability position?
Methodology Current study is applied according to aim and it is analytical – descriptive based on study data gathering method. To study data and information gathering in current study; documentary studies and field observations (questionnaire) were used. Study statistical society include citizens who they resident in urban different tissues. So, citizens were regarded as statistical society in current study. By regarding household approximate value; 390 persons were obtained as sample volume in studied range and they were completed in questionnaire in simple randomized form. Questionnaire measurement tools are standard which they were used in previous studies and questionnaire concept reliability and related subjects were determined according to experts and specialists viewpoint and also their validity were determined by using Alpha- Cronbach’s test. Also One Sample t-test was used to stability position measuring; variance analysis was used for urban tissues comparison at SPSS software framework and, Electer, Vicor, Topsis and Copland multiple criteria decision models (MCDM) were used to urban tissues ranking in EXCEL framework. To draw stability plans; ARC GIS software was applied.
Results and Discussion Results showed that; mean of economic, cultural- social and framework dimensions are higher 3 ; but mean of environmental and political- institutional are lower than 3. Generally mean of obtained 20 variables are in middle level. So we can say; there is no significant difference between theoretical mean (equal with 3) and obtained mean (experimental mean) at 95% confident level and first assumption of study is confirmed according to Ardebil urban tissues middle stability at 95% significant level. Ardebil urban tissues were categorized in 3 classes based on stability. Sectors with organic and planned tissues are located in middle stability; semi-organic tissues sectors and combined villages to city are located in middle stability and outskirt tissue sectors are located in relative stability class. Capland model was obtained from Topsis, Electer, and Vicor models and current tissues ranking at Ardebil city stability was investigated which planned tissue was located in first rank and organic, semi-organic, combined villages and outskirt villages were located in second to fifth ranks respectively.
Conclusion
Study results showed that, most of variables and dimensions have middle stability. Between variables; dynamic and accommodation, accessibility and services, identity, security and health; esprit, placement belonging, social invest, cooperation, involvement and pollutions are located middle to high stability position. Between study dimensions; social dimension has relative proper position and environmental, institutional dimensions have non-stable position and generally Ardebil urban tissues and sectors stability have middle level and also another results showed that, framework dimension has high importance about stability and against another dimensions. In study variables, accessibility and services, endurance capacity, involvement, property value, identity, placement belonging and esprit are as main stability variables. Another result of study relate to stability level difference among urban tissues which semi-organic tissues were located at the first order; combined and combined villages and organic tissues were located at relative stability position or second order or outskirt non-stable tissue. The last result of study relate to different ranks of urban tissues about stability and there is difference possibility in every model. So, it is necessary to use combined model. In Electer model; planned, organic, semi-organic, combined villages and outskirt villages tissue; in Topsis model; organic, planned, semi-organic, combined and outskirt villages tissue; in Vicor model; planned, organic, combined village, semi-organic and outskirt village tissues and at last, in Capland model; planned, organic, semi-organic and combined and outskirt villages tissue were gained first to fifth orders.
