چکیده مقاله :
بافتهای شهری به عنوان محدودههای شهری که در ادوار مختلف شکل میگیرند و میتوانند چند محله را در دل خود جای دهند، جزو اندامهای سازنده شهر محسوب میشوند که برای دستیابی به شهری پایدار و قبل از هر نوع برنامهریزی برای شهر، لازم است پایداری آنها مورد سنجش قرار گیرد. از همین رو هدف تحقیق حاضر سنجش پایداری محلات و بافتهای شهری اردبیل میباشد. جامعهی آماری تحقیق را شهروندان تشکیل میدهند که390 نفر بر اساس فرمول کوکران- به عنوان نمونه انتخاب شدند. روش نمونهگیری به صورت تصادفیِ ساده بوده و پرسشنامه برای آنها توزیع و تکمیل شده است. به منظور تجزیه و تحلیل دادههای حاصل از عملیات میدانی از آزمون آماری t تک نمونهای برای سنجش وضعیت پایداری، از تحلیل واریانس برای مقایسه بافتهای شهری در قالب نرمافزار SPSS و از مدلهای تصمیمگیری چند معیاره (MCDM)، الکتر، ویکور، تاپسیس و کپلند برای رتبهبندی بافتهای شهری در قالب EXCEL استفاده شده است. نتایج حاصل از آزمون t تک نمونهای نشان داد که پایداری محلهای با میانگین عددی 02/3 در حد متوسط میباشد و تحلیل واریانس یکطرفه حاکی از وجود تفاوت بین بافتهای شهر از نظر سطح پایداری میباشد، بگونه ای که در آزمون تعقیبی شفه بافتهای شهری اردبیل در دو دسته ناپایدار و نسبتاٌ پایدار قرار گرفتند. نهایتاً اینکه مدلهای تاپسیس، الکتر، ویکور و مدل ادغامی کپلند نشان داد که به ترتیب بافتهای برنامهریزیشده، ارگانیک، نیمه ارگانیک، روستاهای ادغامی به شهر و حاشیهنشین در رتبه های اول تا پنجم پایداری قرار دارند.
Urban tissues as urban ranges which they create during different periods can locate some sectors in their heart and they are regarded as city creator organs or structures and it is necessary to measure for reaching stable city before every planning. So, the aim of current study in measuring stability of Ardebil city tissues and sectors. Study statistical society include citizens which they were selected as samples with 390 persons based on Cochrane’s formulae. Sampling method was simple randomized case and questionnaire was distributed and completed for their. In order to field operations obtained data analysis; One Sample t-test was used to stability position measuring; one –way Anova 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. One Sample t-test results showed that sector stability with 3/01 mean is in middle level and one –way Anova analysis showed difference between urban tissues according to stability level which in sheffe’s pursue test; Ardebil city tissues were located in non-stable and relative stable classes. At last; Topsis, Electer, Vicor model and Copland combined model showed that planned, organic, semi-organic, combined villages to city and outskirts villages are located at first to fifth ranks.
