بررسي و تحليل سلسله مراتب آسيب پذيري محلات شهر بابلسر به منظور كاهش خطرات زلزله

Analysis of vulnerability hierarchy of Babolsar city neighborhoods faced with earthquake disaster

شهرها دايما در معرض خطر احتمالي بروز انواع مختلفي از مخاطرات محيطي هستند. بر اين اساس بررسي و تحليل مناطق و نواحي آسيب پذير در چارچوب تحليل فضايي شهر به منظور كاهش ابعاد تلفات جاني و مالي ضروري است. انجام چنين اقداماتي در سايه شناخت و تفكيك مناطق پر مخاطره از ساير مناطق و محلات براي انجام اقدامات مناسب در هر محله است. هدف اصلي اين پژوهش بررسي و تحليل فضايي آسيب پذيري كالبدي و اجتماعي-اقتصادي در سطح محلات 16 گانه شهر بابلسر است. روش اين مقاله توصيفي- تحليلي است. داده هاي مورد استفاده از طريق منابع كتابخانه اي، طرح جامع و تفضيلي و سيستم اطلاعات جغرافيايي شهر بابلسر و كار ميداني جمع آوري شده است. به منظور تعيين ضريب آسيب پذيري كالبدي و اجتماعي- اقتصادي از روش تحليل چند معياره SAW استفاده شده است. بر اساس نتايج به دست آمده، آسيب پذيري كالبدي محلات بي بي سرروزه، كاظم آباد و جواديه به ترتيب با 57.01، 56.87 و 56.12 به عنوان آسيب پذيرترين محلات هستند. محلات شهرك ساحلي، شهرك دانشگاه و شهرك قايم با 18.4، 19.3 و 23.25 داراي كمترين ميزان آسيب پذيري مي باشند. همچنين نتايج بدست آمده، محلات بي بي سروزه، كاظم آباد و جواديه به ترتيب با ضريب آسيب پذيري 27.49، 25.92 و 23.93 داراي بيشترين ضريب آسيب پذيري از لحاظ شاخص هاي اجتماعي- اقتصادي را دارا مي باشند و محلات شهرك ساحلي، شهرك دانشگاه و شهرك قايم با ضريب 3.67، 4.42 و 7.36 كمترين آسيب پذيري را دارا هستند.

Analysis of vulnerability hierarchy of Babolsar city neighborhoods faced with earthquake disaster Ali Shamai: Assistant Professor, faculty Geography, Tarbiat Moallem University Azadeh Azimi: MA of Geography and Urban Planning-University of Tarbiat Moaalem, Teharan. Amin Faraji Mollaie: PhD Student in Geography University of Tehran and researcher of institute of human science and society studies - Jahad-e-daneshghahi Abstract Cities as a place of human biology are constantly at risk of several types of natural disasters. Accordingly, appropriate measures in the framework of proper planning is as the best way to reduce loss of life and financial aspects of disasters such as earthquakes, floods, landslides and more. Such measures are only in the shadow of understanding aspects of vulnerability in the studied area. The aim of this paper is study the social and physical vulnerability Babolsar city at the level of16 branches neighborhoods. The method of this paper is descriptive and analytical that in order to collect the data needed, reviewed and studied of library resources and secondary documents (comprehensive plan, detailed plan and the Studies of Babolsar city GIS). In this paper, in order to determine the physical and social- economic vulnerability index was used multiple criteria analysis method of SAW . Based on the results from the perspective of physical vulnerability Bi.bi.sar-roozeh, Kazem Abad and Jvadiyeh neighborhoods respectively 57.01, 56.87 and 56.12 as the most vulnerable communities and while Shahrak-e-saheli, Shahrak-e-daneshga and Sahrak-e-ghaem neighborhoods with a 18.4, 19.3 and 23.25 are the lowest. Based on what is presented in Table 8 Bi.bi.sar-roozeh, Jvadiyeh neighborhoods and Kazem Abad vulnerabilities coefficient respectively 27.49, 25.92 and 23.93 are the most vulnerable from the perspective of social- economic indicators and Shahrak-e-saheli, Shahrak-e-daneshga and Sahrak-e-ghaem neighborhoods with 3.67, 4.42 and 7.36 have the lowest vulnerability.
