بررسي وضعيت مسكن غيررسمي در شهرهاي استان تهران با استفاده از تحليل خوشه اي

Study of informal devilling situation in Tehran province cities using cluster Analysis

بيش ترين و مهمترين كاربري هر شهر، محل زندگي و مسكن شهروندان مي باشد. در استان تهران، ويژگي هاي كلانشهر تهران به عنوان پايتخت سياسي، اداري و تمركز منابع اقتصادي، اجتماعي، سرمايه و صنعت باعث شده است كه از دهه هاي گذشته نقش قطبي را در فضاي سرزميني كشور ايفا نمايد و با اين عمل سيل مهاجران از ساير نقاط كشور به اين منطقه سرازير شده است. در اين ميان مهاجران تازه وارد كه توانايي اسكان در شهر تهران را ندارند، به ناچار در مجتمع هاي زيستي اطراف اين كلانشهر استقرار يافته اند . اين هجوم كه متناسب با ظرفيت ها، امكانات و مديريت شهري نبوده است در مسكن شهري باعث ايجاد اخلال هاي گوناگوني شده است. در اين مطالعه، شاخص هاي كمي و كيفي نقاط شهري استان تهران مورد ارزيابي قرار گرفته و با استفاده از مدل تحليل خوشه اي به گروه بندي شهرهاي استان تهران بر اساس شاخص هاي كمي و كيفي و نمره استاندارد (Z) اين شاخص ها، پرداخته شده است. نتايج حاصل از تحقيق نشان مي دهد كه شهرهاي طبقات چهارگانه از نظر شاخص هاي كمي و كيفي با هم اختلاف داشته و بيشترين تعداد شهرها از نظر شاخص هاي كمي و كيفي در وضعيت نامناسبي قرار دارند. مجموع شرايط حاكي از روند غير اصولي و بدون برنامه مشخص و مرتبط با فعاليت هاي اجرايي در حوزه مسكن است. اين وضعيت نامطلوب شاخص هاي كمي و كيفي و دسترسي به خدمات اساسي مسكن، بازتاب خود را در زندگي فردي، اجتماعي، فرهنگي، سياسي و تربيتي شهروندان منعكس مي نمايد.
