| چکیده | ||
| در اغلب شهرهای خشک و بیابانی، فقدان کمربندهای سبز کارآمد، کمبود منابع آب، توپوگرافی محدودکننده و مهاجرت روستاها به فضاهای شهری، همراه با فشار بر زیرساختها، پیامدهای زیستمحیطی، اجتماعی و اقتصادی قابل توجهی به دنبال دارد. این مسائل موجب کاهش کارکرد زیست محیطی، کاهش تابآوری شهری و تشدید نابرابریهای دسترسی به فضاهای سبز میشود. هدف اصلی این تحقیق، ارزیابی اثربخشی کمربند سبز در کنترل گسترش بیرویۀ شهر و هدایت توسعه پایدار شهری در محدوده محور جنوب غربی زاهدان است و از این طریق بهبود همزمان پایداری زیستمحیطی، کاربری اراضی و رفاه اجتماعی را دنبال میکند. روش مورد استفاده در ایـن پـژوهش، توصـیفی- تحلیلـی است. بدین منظور ابتدا اطلاعات از طریق منابع کتابخانهای، مقـالات و منابع اینترنتی جمعآوری و بهمنظور شناخت بیشـتر از محدوده مورد مطالعه، برداشت میدانی صورت گرفته است. در گام بعدی، با استفاده از پرسشنامه خبرگان و با به کارگیری روش دلفی، نظرات کارشناسی برای تبیین و اولویتبندی راهکارها و ضریب هماهنگی آنها با استفاده از نرمافزار spss نسبت به هم، جمعآوری و تحلیل شده است. پس از آنکه روش دلفی در سه دور متوالی با مشارکت خبرگان دانشگاهی و کارشناسان اداری اجرا شد، نتایج حاصل از تحلیل یافتهها نشان داد ضریب هماهنگی کندال اجماع بین اعضا از دور اول تا سوم به طور قابل توجهی افزایش یافته است و از 234/0 به 724/0 رسیده است. یافتههای پژوهش نشان میدهد که کمربند سبز محور جنوب غربی زاهدان میتواند آلودگی هوا و گردوغبار را کاهش دهد، اما با چالشهای اصلی کمبود منابع آبی، نیاز به مدیریت هوشمند آب و انتخاب گونههای سازگار با اقلیم خشک روبهرو است. با وجود اینکه با رویکرد توسعه پایدار و استفاده از فناوریهای نوین و گیاهان مقاوم به خشکی مانند زری اسکاپ امکانپذیر است و میتواند به بهبود کیفیت هوا کمک کند، اما نتوانسته کنترل رشد و توسعه شهری را به طور کامل تأمین کند و به سیاستها و راهکارهای جامع بلندمدت نیاز دارد. این طرح میتواند بهعنوان بخشی از راهکار کلان مدیریت شهری برای کاهش آلودگی هوا و گردوغبار و در عین حال حفظ حریم شهر با پیراشهر عمل کند، اما موفقیت آن مستلزم همکاری بین سازمانی، قوانین شفاف و مشارکت مردمی است. | ||

| چکیده [English] | ||
| In arid and desert cities, the lack of efficient green belts, water resources, restrictive topography, and rural migration to urban spaces, along with pressure on infrastructure, have significant environmental, social, and economic consequences. These issues lead to a decrease in ecological function, reduced urban resilience, and exacerbated inequalities in access to green spaces. The main objective of this research is to evaluate the effectiveness of the green belt in controlling urban sprawl and guiding sustainable urban development within the southwestern axis of Zahedan. And through this, it simultaneously improves environmental sustainability, land use and social welfare. The method used in this research is descriptive-analytical. For this purpose, information was first collected through library resources, articles and internet resources, and in order to better understand the study area, field observations were carried out. In the next step, using an expert questionnaire and the Delphi method, expert opinions were collected and analyzed to explain and prioritize the solutions and their coordination coefficients using SPSS software. After the Delphi method was implemented in three consecutive rounds with the participation of academic and administrative experts, the results of the analysis of the findings showed that the Kendall coordination coefficient of consensus among members increased significantly from the first to the third round and has increased from 0.234 to 0.724. The research findings show that the green belt of the southwestern axis of Zahedan can reduce air pollution and dust, but it faces the main challenges of lack of water resources, the need for smart water management, and the selection of species adapted to the dry climate. Although it is possible with a sustainable development approach and the use of modern technologies and drought-resistant plants such as Xeriscape and can help improve air quality, it has not been able to fully control urban growth and development and requires comprehensive long-term policies and solutions. This plan can serve as part of a comprehensive urban management strategy to reduce air and dust pollution while preserving the privacy of the city and its suburbs, but its success requires interagency cooperation, transparent laws, and public participation | ||
