نگاشت فضایی وضعیت زوال‌یافتگی پهنه‌های میراثی به مثابه پیامد مداخله‌های بازآفرینی (مطالعه موردی: پهنه میراثی شهر شیراز)

زوال یافتگی پهنه های میراثی در شهرهای تاریخی، به مثابه عامل اصلی عقب ماندگی ازجریان توسعه، سبب ساز افول کیفیت زندگی و کاهش جذابیت پهنه برای ساکنان می شود. بنابراین، شناسایی و تحلیل فضایی-مکانی وقوع زوال یافتگی بمنظور تغییر و اصلاح رویکرد مداخله در پهنه های فرسوده شهری حائزاهمیت است. درهمین خصوص افت وخیزهای پهنۀمیراثی 378هکتاری شهرشیراز و آسیب های احتمالی وارد شده به آن، روند فرساینده این مکان را سبب شده است. در این رابطه پژوهش پیش رو در جست و جوی این موضوع برآمده است که زوال یافتگی پهنۀمیراثی شیراز از چه الگویی پیروی می کند؟و آیا مداخله های انجام پذیرفته، موجبات زوال یافتگی بیش از پیش را فراهم ساخته است؟روش شناسی پژوهش از نوع تحلیل سببی به روش پژوهش شبه تجربی است که ابزارهای تحلیل فضایی خوشه های گرم و سرد و تحلیل رگرسیون فضایی را به کار گرفته است. نتایج پژوهش نشان می دهد که بدلیل اثرگذاری نوع مداخله های متفاوت در پهنه میراثی شهر شیراز، زوال یافتگی در زمینه های اقتصادی و اجتماعی شدت یافته و این امر مستلزم سیاست گذاری صحیح در نحوه مداخلات این پهنه هاست.

spatial mapping of the deterioration status of shiraz's heritage area as a consequence of regeneration interventions

heritage areas in most cities of iran, contrary to the values hidden in them, do not respond to the needs of their main residents today, and for this reason, they face the phenomenon of inefficiency and deterioration. the ineffectiveness of the conventional approaches to intervention in heritage areas has made urban development experts search for more sustainable methods of intervention. the deterioration of heritage areas in historic cities, as the main factor behind the development process, causes a decline in the quality of life and a decrease in the attractiveness of the area for residents. the ups and downs of the 378-hectare heritage area of shiraz city and the possible damage done to it have caused an eroding process of destruction of the physical and semantic values of this historical-cultural site. this area has witnessed the collapse of the local community and increasing decline as a result of the migration of indigenous residents over the last 2 -3 decades and their replacement by poor and socially disadvantaged people and foreign nationals. urban decay is a multidimensional and complex phenomenon that includes physical, socio-economic, and environmental dimensions, and its identification requires indexing. therefore, identifying and analyzing the spatial-spatial occurrence of decay is important in order to identify the priority of regeneration or changing and modifying the intervention approach in degraded urban areas. in this regard, the present research seeks to investigate what place-spatial pattern the deterioration of shiraz's heritage area follows. and have the interventions carried out in the area in the form of improvement, renovation, and recreation plans caused further deterioration? the research methodology is a causal analysis using a quasi-experimental research method that seeks to identify the net consequences of the intervention by comparing it with control areas using spatial analysis tools of hot and cold clusters and spatial regression analysis. in this regard, in the first step, by reviewing relevant sources, the factors of deterioration were identified, and in the second step, after selecting the city of shiraz as a case study, the area was divided into three parts: the heritage zone, the surrounding areas, and the entire shiraz metropolis, and the changes that have occurred in recent years were compared in the form of deterioration variables. then, the relationship between the types of interventions as independent variables and the deterioration measures as dependent variables was analyzed using spatial regression. the results of the research show that due to the impact of different types of interventions in the heritage zone of shiraz, decline and deterioration have intensified in all areas, including economic and social ones. in addition to educating and informing the residents of these areas, this requires a specific framework to coordinate policies regarding proper management and intervention in this area in the areas of commercialization, widening of streets, and acquisition and destruction, in order to pave the way for evaluating policies and interventions in order to develop a desirable vision for heritage areas, especially the heritage area of shiraz.
