چکیده

به‌دلیل خشک‌سالی‌های گسترده و متوالی در فلات ایران و پی‌آمدهای زیست‌محیطی به‌وجودآمده در برخی از کشورهای همسایه در سال‌های اخیر، باید در جست‌و‌جوی راه‌کارهای جدید برای مبارزه با ریزگردها و دیگر ‌آسیب‌های احتمالی در سال‌های آینده باشیم. یکی از این راه‌کارها، توسعه‌ی فضای سبز متناسب با خصوصیات زیست‌اقلیمی و خصوصیات حوضه‌های آبخیز و امکانات موجود در هر منطقه است. مکان‌یابی فضاهای سبز از ضرورت‌های توسعه‌ی پایدار شهری است. به‌علت گسترش شهرها و مکان‌یابی نادرست و بی‌توجهی به معیارهای مربوطه، مکان‌ها و نحوه‌ی توسعه‌ی فضای سبز درون‌ شهرها و عرصه‌های طبیعی اطراف بسیاری از آن‌ها مطلوب نیست. در این پژوهش، ابتدا وضعیت فضای سبز موجود براساس شاخص سرانه‌ی زیست‌محیطی و شهرسازی ارزیابی شد، و سپس مکان‌یابی با استفاده از تحلیل سلسله‌مراتبی و توابع سامانه‌ی اطلاعات جغرافیایی و لحاظ‌کردن شاخص هم‌جواری برای احداثِ فضای سبز به‌انجام رسید. نقشه‌ی محدوده‌ی بررسی‌شده از نظر تناسب مکانی برای احداث فضای سبز جدید براساس معیار هم‌جواری تهیه شد.

چکیده [English]

Due to widespread and continuous drought in the Iranian Plateau and environmental problems in the neighboring countries during the recent decades, we should find a new approach to combat dust and other environmental problems in the southern cities in our country in the future.  An approach in this field is an extension of green spaces in accordance with the bio-climatic and watershed properties, and current facilities in any area. Localizing urban green landscape is necessary for the urban sustainable development. Localization and development of the established green space was not desirable due to the expansion of cities, incorrect positioning and lack of attention to standards. In this article, we evaluate the status of the existing urban green space per capita based on the environmental and urban development. Through the combined hierarchical model and the GIS functions, and considering the proximity, we discussed the locations for establishment of the green space. We developed a green space map in terms of the appropriateness of the place for establishing a new green space based on the proximity criteria.
