ارزیابی تطبیقی زیست پذیری شهری و مسکن گزینی بافت های فرسوده شهری(مطالعه موردی: بافت فرسوده شهر قیدار)

 در عصر حاضر، بافت های فرسوده شهری به عنوان جزء ارزشمندی از پیکره ی اصلی هر شهر، سازگاری مطلوبی با شرایط زندگی امروزی شهروندان ندارند. به سخن دیگر، عدم دسترسی مناسب به معیارهای زندگی امروزی، فقدان سرزندگی و زیست پذیری، از اساسی ترین مشکلات این بافت ها، محسوب می گردند. بر‌این ‌اساس، هدف اصلی این پژوهش، ارزیابی تطبیقی زیست پذیری شهری و مسکن گزینی بافت فرسوده شهر قیدار می باشد. پژوهش حاضر، با روش توصیفی-تحلیلی انجام گردیده و برای دستیابی به این هدف، از دو بخش مطالعات اسنادی و میدانی(پرسشنامه) استفاده گردیده است. به فراخور نیاز تحقیق، از نرم افزارهایspss,arc gis,lisrel و تکنیک تحلیل شبکه ای، استفاده شده است. نتایج تحقیق، حاکی از اهمیت موضوع در دو قالب نظری و عملی می باشد: ویژگی نظری این تحقیق، کمک به پیشرفت تخصصی و بسط و گسترش ادبیات علمی موضوع زیست پذیری شهری می باشد و ارزش عملی نیز آن است که با عنایت به وجود عوامل گوناگون تاثیر گذار بر وضعیت زیست پذیری، گونه های متفاوت از این وضعیت در پهنه بافت فرسوده شهر قیدار ملاحظه گردید. به طور‌ی‌که محله‌ی کوی شریعتی با میانگین شاخص(60/5) گونه شماره 1، تختی(50/2) گونه شماره 2، بقعه‌ی قیدارنبی(ع)(48) گونه شماره 3، باب الحوائج(46/2) گونه شماره 4 و محلات سرچشمه و چاله محله(44/2) در رده‌ی گونه 5 قرار می‌گیرد. بر اساس نتایج آزمون ضریب همبستگی پیرسون نیز، رابطه مستقیم و معنی داری(0/992=r) بین زیست ‌پذیری و مسکن گزینی مشاهده می‌شود. بدین معنی که با افزایش سطح زیست پذیری در بافت فرسوده‌ی شهر قیدار، میزان مسکن گزینی در بافت نیز افزایش یافته و رابطه مستقیمی بین این دو متغیر، وجود دارد و از نظر زیست پذیری و مسکن گزینی محله های کوی شریعتی(11/06)(2/89) و تختی(10/98)(2/86) نسبت به سایر محله های بافت فرسوده‌ی شهر قیدار، امتیاز بالاتری را کسب و در نتیجه در جهت سکونت، مطلوب‌تر و دلپذیرتر به نظر می رسند. 

comparative assessment of urban viability and housing replacement of urban dilapidated tissues (case study: dilapidated tissue of qeydar city)

introduction: in today's era, worn-out urban textures, as a valuable part of the main body of every city, are not compatible with the current living conditions of citizens. in other words, the lack of proper access to today's living standards, the lack of vitality and livability are considered to be one of the most basic problems of these tissues. based on this, the main goal of this research is thecomparative evaluation of urban livability and housing selection of the dilapidated fabric of qeydarcity. the current research intends to do a comparative study of urban livability and housing selectionin the worn-out neighborhoods of qeydar city (6 neighborhoods) with a population of 4011 people,after identifying micro and macro factors affecting livability and housing selection in the dilapidatedtexture of qeydar city, considering four economic, social, physical and environmental aspects.therefore, according to the issues raised, the goals of this research are as follows: 1- knowing thelivability levels of the worn-out neighborhoods of qeydar city and its typology; 2- analysis of thestructure and mechanisms affecting the situation governing the livability of the worn-out fabric ofqeydar city; 3- comparative evaluation of livability and housing selection in the dilapidated context ofqeydar city. therefore, in the current research, we are looking for answers to these questions: 1- whatare the most important structures and mechanisms affecting the livability of the worn-out fabric ofqeydar city? 2- is there a significant relationship between improving the quality of the residentialenvironment and, as a result, increasing the livability of neighborhoods and the level of people's desireto choose housing in the worn-out tissues of qeydar city?matherials: the current research is of an applied type, and in terms of method, a descriptiveanalyticalmethod has been used. documentary and field methods have been used to collect data andinformation. in order to achieve this goal, to collect information from the library document method(studying documents, statistics and research history) and field (observation and interview with experts,elites and residents through the questionnaire tool) and secondary data analysis. or data-mining hasbeen used from the information of the approved comprehensive upstream plans and the reconstructionand renovation plan of the worn-out fabric of qeydar city. the statistical population in this researchincludes the residents of the worn-out fabric of qeydar city (4011 people). the questionnaire has beendeveloped in three communities: 1- citizens, 2- experts, 3- experts and experts including (professors,researchers, experts from related departments and experts from the private sector involved in urbanaffairs) . in order to determine the validity of the questionnaire, before distributing the questionnaire,the opinions of 80 experts, experts and professors of urban planning and urban sociology were usedregarding the structure of the questionnaire and its content, and the indicators were modified accordingto the opinion of these professors and experts. cronbach's alpha coefficient was also used to determinethe reliability of the research questionnaire. for this purpose, the questionnaire was pre-tested beforeexamining and analyzing the findings. questionnaire of the residents of the dilapidated city of qeydarconsisting of 4 dimensions and 52 items, and a questionnaire of experts with a number of 17 items, which is rated based on a five-point likert scale from very low to very high (this is how positive itemsare scored is: very low: 1, low: 2, medium: 3, high: 4, very high: 5). after verifying the validity of thequestionnaire by the experts, cronbach's alpha command was implemented in order to determine thereliability in the spss software environment and it was confirmed with the result (the questionnaire ofresidents of baft 0.623, 0.992 and the questionnaire of experts 0.735).discussion of results : according to the investigations, the results indicate that five different specieshave been identified in the worn-out texture of qeydar city with an area of 27 hectares, based on thedifferent levels of viability in the localities of these textures. therefore, it can be acknowledged that inthe area of the worn-out tissue of qeydar city, in terms of the four dimensions (social, economic,physical and environmental), different conditions of livability can be seen on the level of the worn-outtissue and different spatial patterns. it has been manifested from the state of viability at the tissuelevel. therefore, based on the average points obtained, among the worn-out fabric neighborhoods ofqeydar city, koi shariati neighborhood (60.5) is in category one, takhti neighborhood (50.2) is incategory two, qeydar -nabi (a.s.) neighborhood (48) ) in type three, bab-al-hawaij neighborhood(46.2) is in type four, and sarcheshmeh and chaleh neighborhood (44.2) are in type five. and it canalso be said that in the area of the worn-out fabric of qeydar city, except for sarcheshmeh and chalehmahaleh neighborhoods, which have many commonalities and are identified and placed in the samecategory, the rest of the neighborhoods are located in different categories and each one, they have adifferent spatial pattern in terms of livability. and based on the results of this research, the averagescore obtained in the neighborhoods of koi shariati (11.06) and takhti (10.98) is more than otherneighborhoods of the worn-out fabric of qeydar city and the low percentages of livability arerespectively in the neighborhoods of qeydar nabi (pbuh) (10.72), bab al-hawaij (10.30),sarcheshmeh (9.92) and chaleh mahalla (9.03), this is a sign of the ruler. the existence ofunfavorable living conditions in these neighborhoods (baqea qeydar nabi (pbuh), bab al-hawaij,sarchesmeh and chaleh mahalah) and of course it is clear that the root of these unfavorable conditionscan be found in the socio-economic base of its residents, physical wear and tear he searched for theestablishment of houses on old underground slums (rural context) and... . also, based on themeasurement and the results of the one-sample t-test, regarding the housing-choice situation of theresidents of the worn-out neighborhoods of qeydar city and their level of interest and willingness tolive and stay in these neighborhoods, it can be said that according to koi shariati (89 2.2), takhti(2.86), qeydar nabi tomb (2.72), bab al-hawaij (2.53) and sarcheshmeh (2.31) and chaleh mahalla(2.06) in ranks one to five have been placed. the interesting point is that the order and the averagescore of the localities in the one-sample t-test about the housing selection situation follow the order ofthe livability of the localities and its types of tissue and are consistent with each other.conclusions: this means that with increasing the level of livability in the dilapidated fabric of qeydarcity, the rate of housing in the fabric has also increased and there is a direct relationship between thesetwo variables, and in terms of livability and housing in shariati neighborhoods (11.06) (2.89) andtakhti (10.98) (2.86) have a higher score than other neighborhoods in the dilapidated area of qeydarcity, and as a result, they seem more desirable and pleasant in terms of living.
