چکیده:
بافتهای فرسوده که کمبود خدمات شهری و ناپایداری در آنها مشهود است، دارای ظرفیتهای فروانی برای حرکت به سمت توسعه درونی در چارچوب توسعه پایدار میباشند. تحقیق حاضر به شناسایی ظرفیتهای موجود اراضی ناکارآمد و فرسوده شهری در راستای توسعه درونی پرداخته است. محدوده مورد مطالعه در این تحقیق، مناطق 4 و 14 شهر تهران است. تحقیق از نوع کاربردی است و با روش توصیفی ـ تحلیلی به تجزیه و تحلیل اطلاعات پرداخته است. جامعه نمونه شامل 30 نفر از کارشناسان که با روش گلوله برفی شناسایی شدهاند. ارزیابی ظرفیتهای توسعه درونی در اراضی ناکارآمد و بافت فرسوده با استفاده از روش Fuzyy GIS انجام شده است. نتایج به دست آمده از نقشههای ترکیب لایهها و شاخصهای تحقیق نشان میدهد که محدودههای با اولویت بالا و بسیار بالا در بافت فرسوده منطقه 14 تهران در راستای توسعه درونی حدود 116.82 هکتار ( 60.6% از کل مساحت) را به خود اختصاص داده است. این در حالی است که محدودههای با اولویت بالا و بسیار بالا در توسعه درونی در منطقه 4 شهر تهران حدود 25.05 هکتار از مساحت بافت فرسوده منطقه 4 تهران است که حدود 82.4% مساحت از کل بافت فرسوده و زمینهای فاقد بنا در این منطقه از تهران را شامل میشود، اما به علت بالا بودن حجم اراضی ناکارآمد و فرسوده منطقه 14 شهر تهران حجم جمعیت پذیری این منطقه بیشتر از منطقه 4 است. مقایسه معیارهای موثر بر توسعه درونی در اراضی ناکارآمد و فرسوده منطقه 4 و 14 شهر تهران نشان میدهد، که در منطقه 14 معیار مساحت زمین با امتیاز 0.412 و در منطقه 4، شاخص کاربری زمین با امتیاز 0.346 بیشترین اهمیت را نسبت به سایر شاخصها دارا میباشد
Worn-out textures, in which urban service scarcity and instability are evident, have enormous capacities to move towards internal development within the context of sustainable development. The present study identifies the existing capacities of inefficient and dilapidated urban land for internal development. The study area in this study is districts 4 and 14 in Tehran. The research is applied and has analyzed the information with descriptive-analytical method. The sample population includes 30 experts identified by snowball method. Evaluation of internal development capacities in dysfunctional lands and worn-out textures was performed using Fuzyy GIS method. The results obtained from the maps of layers composition and research indices show that high and very high priority areas in the worn-out texture of District 14 of Tehran for internal development of about 116.82 ha (60.6% of total area). ). However, high priority and very high priority areas for internal development in District 4 of Tehran are about 25.05 ha of deteriorated tissue area of District 4 of Tehran which is about 82.4% of the total area of deteriorated tissue and lack of areas in this area. The district covers Tehran, but due to the high volume of dysfunctional and dilapidated land in the 14th district of Tehran the population is larger than the 4th district. Comparison of criteria affecting internal development in dysfunctional and dilapidated lands of district 4 and 14 shows that in area 14 criteria land area with 0.412 points and in area 4 land use index with 0.346 points more than other indexes.
