چکیده

امروزه استفاده از شاخص­های اقتصادی، اجتماعی، فرهنگی و بهداشتی می­تواند معیاری مناسب برای تعیین جایگاه روستا و رفع مشکلات و نارسایی­های جهت نیل به رفاه اقتصادی و سلامتی اجتماعی باشد. هدف این تحقیق بررسی توسعه­یافتگی سکونتگاه­های روستایی بخش اصلاندوز شهرستان پارس­آباد می­باشد. تعداد سکونتگاه­ها 118 مورد و تعداد شاخص 27 مورد ­اشند. این تحقیق از نوع توصیفی بود. جهت رتبه­بندی سکونتگاه­های بخش از روشTOPSIS  استفاده شد. نتایج نشان داد که بر اساس میزان  محاسبه شده، حداقل  083/0 برای قشلاق گدایلو و حداکثر 67/0 برای شهر اصلاندوز می­باشد و میانگین آن برابر 16/0 است. دامنه نوسان سطح توسعه­یافتگی سکونتگاه­های بخش 58/0 برآورد شده است. هم­چنین 13 سکونتگاه در حال توسعه و 103 سکونتگاه توسعه­نیافته می­باشند. تحلیل واریانس نشان داد که تفاوت معناداری بین میانگین­های های سطوح توسعه وجود دارد.

چکیده [English]

Large earthquakes usually cause huge damages to human life. Street network vulnerability makes the rescue operation to encounter serious difficulties especially at the first 72 hours after the incident. Today, physical expansion and high density of great cities, due to no attention to hierarchical street network, narrow access roads, large distance from medical care centers and location at areas with high seismic risk, would lead to a perilous and unpredictable situation in case of the earthquake. Occurrence of earthquakes with large magnitude would destroy the functionality of street networks and cause large amount of casualties and major financial damages. In Tabriz city, the areas of first and fifth zones are equal to 3327 hectares. The area of first and fifth zones is over 2844 and 483 ha respectively. According to current estimates, the population of these zones is equal to over 458939 people. In this research using 12 indexes such as: land use, width of roads, height of buildings, street inclusion, population and construction density, buildings area, quality, materials and antiquity of building, access to medical centers, distance and proximity to major faults vulnerability degree of street networks in zones 1 and 5 of detailed plan of Tabriz against the earthquake is calculated through overlaying maps and data in combination with IHWP method and GIS. The article concludes that buildings alongside the streets with high population and building density, low building quality, far to rescue centers and high level of inclusion represent high rate of vulnerability, compared with other buildings. Also highways and streets with substantial width and low building and population density hold little values of vulnerability. By moving on from east to west of the zones, the vulnerability increases. This vulnerability of streets is in high level in the central zones. Therefore, the existing street networks in the center will be unable to perform their role at the case of occurrence of earthquake.
