چکیده مقاله :
در این بررسی شاخص زیستی و کیفیت آب رودخانه خنگ در شهرستان سپیدان طی سال های 1388-1387 با استفاده از فون حشرات آبزی از اعماق مختلف آب از مکان های مختلف رودخانه جمع آوری و تا سطح خانواده شناسایی شدند. سپس با استفاده از فرمول شاخص زیستی، کیفیت آب تعیین گردید. در مجموع 32 خانواده از 7 راسته حشرات شامل Coleoptera، Ephemeroptera، Diptera، Plecoptera، Odonata، Hemiptera و Trichoptera از 4 کد زیستگاهی رودخانه مزبور جمع آوری و شناسایی شدند. در تحقیق صورت گرفته بر رودخانه خنگ، شاخص زیستی این رودخانه 79/3 به دست آمد که کیفیت آب آن بسیار خوب (آلودگی آب به مواد آلی ناچیز) تعیین گردید.
In this research, biotic indexand water quality of Khong river of Sepidan region in Fars province was estimated by using aquatic insect fauna during 2009-2010. The aquatic insect fauna were collected from different places of the river and identified in family level. Then the water quality was estimated by Hilssenhoff biotic index formula. A total of 39 families from 7 orders of insects (Trichoptera, Hemiptera, Odonata, Plecoptera,Diptera, Ephemeroptera andColeoptera) were collected and identified from 4station of the river. In this research, biotic index of the Khongriver was estimated 3.79 and quality was excellent (Slight level of pollution by organic material).
