چکیده
هدف: هدف این پژوهش ارزیابی خدمات اکولوژیکی، زیست‌محیطی و اقتصادی پوشش گیاهی شهری در شبکه سبز ائل‌گلی شهر تبریز است. تمرکز اصلی تحقیق بر نقش زیرساخت‌های سبز در کاهش چالش‌های زیست‌محیطی شهری از طریق جذب و ذخیره کربن، کاهش آلودگی هوا و مدیریت رواناب‌های سطحی است. این مطالعه با هدف ارائه بینش‌هایی برای برنامه‌ریزی آگاهانه شهری و توسعه پایدار فضاهای سبز انجام شده است.

روش پژوهش: این مطالعه یک پژوهش کمی است که از روش‌های کتابخانه‌ای (بررسی ادبیات موضوع، تعاریف زیرساخت‌های سبز شهری و دیدگاه‌های متخصصان) و مشاهده میدانی همراه با تحلیل آماری توسط نرم‌افزار i-Tree برای جمع‌آوری داده‌ها استفاده می‌کند. تحلیل داده‌ها به روش توصیفی-تحلیلی انجام شده و نتایج در قالب جداول ارائه شده است.

پارامترهای ارزیابی: خدمات اکوسیستمی مورد ارزیابی شامل جذب و ذخیره کربن، کاهش آلودگی هوا، و مدیریت رواناب‌های سطحی می‌باشد.

یافته‌ها: شبکه سبز ائل‌گلی در تبریز سالانه حدود ۷۵.۸۴ تن کربن را جذب و ذخیره می‌کند.

این شبکه همچنین سالانه حدود ۲.۰۷۷ تن از آلاینده‌های هوا را حذف می‌نماید.

در میان آلاینده‌های بررسی‌شده، ازن (O₃) بیشترین و کربن مونوکسید (CO) کمترین میزان حذف را دارا بودند.

نتایج بر اهمیت شبکه سبز ائل‌گلی در بهبود کیفیت هوای شهری و نقش آن در کاهش آثار تغییر اقلیم تأکید دارند.

نتیجه‌گیری: این پژوهش با استفاده از نرم‌افزار i-Tree Canopy 7.1، خدمات اکوسیستمی پارک ائل‌گلی تبریز را از جنبه‌های اکولوژیکی و اقتصادی ارزیابی کرد. مساحت پوشش گیاهی تعیین و درختان و درختچه‌ها شمارش شدند تا ذخیره کربن، حذف آلاینده‌ها و مهار رواناب سطحی محاسبه گردد. نتایج نشان داد پارک سالانه ۷۵.۸۴ تن کربن ترسیب، ۲،۰۷۷ کیلوگرم آلاینده هوا را حذف و ۱.۹۲ لیتر رواناب سطحی را مهار می‌کند. با توجه به محدودیت‌های نرم‌افزار، پیشنهاد می‌شود با حفاظت از درختان ارزشمند، افزایش گونه‌های گیاهی مؤثر، توسعه پوشش گیاهی متراکم و استفاده از شبکه‌های بیوریتنشن، بهره‌وری اکوسیستمی پارک و سایر فضاهای سبز شهری ارتقا یابد.

چکیده English

Objective: The study aims to evaluate the ecological, environmental, and economic services provided by urban vegetation within the El-Goli green network in Tabriz. Specifically, it focuses on assessing the role of green infrastructure in mitigating urban environmental challenges through carbon sequestration, air pollution reduction, and surface runoff management. The research seeks to provide insights that support informed urban planning and the sustainable expansion of green spaces.

Methods: This study is a quantitative research that employed library-based methods (literature review, definitions of urban green infrastructure, and expert opinions) and field observations, combined with statistical analysis using i-Tree software for data collection. Data analysis was conducted using a descriptive-analytical approach, and the results are presented in tables.

Evaluation Parameters: The ecosystem services assessed in this study include carbon sequestration and storage, air pollution reduction, and stormwater management.Assessment Parameters: Key ecosystem services evaluated include carbon capture and storage, air pollution reduction, and surface runoff management.

Results: The El-Goli green network in Tabriz sequesters approximately 75.84 tons of carbon annually.

The green network removes about 2,077 tons of air pollutants per year.

Among the pollutants analyzed, ozone was the most effectively removed, while carbon monoxide showed the lowest removal rate.

The findings underscore the significant role of the El-Goli green network in improving urban air quality and contributing to climate change mitigation.

Conclusions:

This study used i-Tree Canopy 7.1 to assess the ecosystem services of El-Goli Park in Tabriz from ecological and economic perspectives. The vegetation area was measured, and trees and shrubs were counted to estimate carbon storage, air pollutant removal, and surface runoff mitigation. Results showed that the park annually sequesters 75.84 tons of carbon, removes 2,077 kg of air pollutants, and mitigates 1.92 liters of surface runoff. Considering the software’s limitations, it is recommended that ecosystem productivity in the park and other urban green spaces be enhanced through the protection of valuable trees, increasing effective plant species, developing dense vegetation cover, and implementing bioretention networks.
