چکیده

با توجه به اهمیت و وسعت قابل‌توجه شبکه آبیاری و زهکشی کوثر، مسائل محیط‌زیستی شبکه بررسی می‎گردد. هدف از پژوهش حاضر ارزیابی اثرات ‌محیط­زیستی شبکه آبیاری و زهکشی کوثر واقع در حوضه مرکزی کرخه در استان خوزستان، به کمک دو روش ماتریس آیکلد مرسوم و آیکلد اصلاح‌شده بود. به‌منظور بررسی پارامترهای محیط‌زیستی، از سه محیط فیزیکی، زیستی و اجتماعی-اقتصادی استفاده شد. سپس با استفاده از دو روش ماتریس آیکلد مرسوم و آیکلد اصلاح شده، اثر هریک از ریزفعالیت‌های طرح بر عوامل زیست‌محیطی منطقه مطالعاتی، در فاز بهره‌برداری به تفکیک سه محیط‌ مذکور سنجیده شد. بدین‌صورت که با توجه به هر سه محیط ماتریسی طراحی گردید، که توسط متخصصین و کارشناسان محیط‌زیست تکمیل‌شده و میانگین  امتیازات معیار ارزیابی قرار گرفت. نتایج نشان داد که بیش­ترین اثرات مثبت مربوط به محیط اجتماعی-اقتصادی می‎باشد. لازم به ذکر است، مجموع کل ارزش‏های مثبت با استفاده از ماتریس آیکلد مرسوم و آیکلد اصلاح‌شده به‌ترتیب برابر 793 و 9/458 و برای ارزش‌های منفی معادل 447 و 8/285 بود. بنابراین، هر دو ماتریس در ارزیابی اثرات برآورد خوب و منطقی از خود نشان داده و درنتیجه اجرای شبکه آبیاری و زهکشی کوثر مورد تأیید می‎باشد.

چکیده [English]

With respect to the importance and considerable extent of the Kosar irrigation and drainage network, the environmental issues of the network are investigated. The purpose of this study was to evaluate the environmental effects of Kowsar irrigation and drainage network located in the central basin of Karkheh in Khuzestan province, using two methods: conventional and modified ICOLD matrices. To study the environmental parameters, three physical, biological and socio-economic environments were used. Then, using two methods of conventional and modified ICOLD matrices, the effect of each of the project micro-activities on the environmental factors of the study area was measured in the operation phase separately for the three mentioned environments. Thus, a matrix was designed according to all three environments, which was completed by environmental experts and the average score of the evaluation criteria was considered. The results showed that the most positive effects are related to the socio-economic environment. It should be noted that the sum of positive values using conventional and modified ICOLD matrices was 793 and 458.9, respectively, and for negative values was 447 and 285.8, respectively. Therefore, both matrices showed reasonable and good fitness in estimating the impacts and thus the implementation of the Kawser irrigation and drainage network is verified.
