| چکیده | ||
| هدف از این تحقیق، بررسی کیفی آب رودخانه زایندهرود با استفاده از جوامع بیمهرگان کفزی در فاصله پائیز 96 تا بهار 97 میباشد. بدین منظور از بالا دست تا پائیندست زایندهرود در شش ایستگاه، نمونهبرداری از رسوب انجام و با استفاده از فرمالین 4% تثبیت شد و با محلول رزبنگال رنگآمیزی و بر اساس کلیدهای شناسایی، شناسایی گردید. در فصل بهار، 8 خانواده متعلق به 6 راسته، در فصل پائیز، 11 خانواده متعلق به 7 راسته و در فصل زمستان، 6 خانواده متعلق به 4 راسته شناسایی شد. بر اساس همه شاخصها، همه ایستگاهها و همه فصول در رده آلوده قرار میگیرند.با توجه به خشکی زایندهرود در دهه اخیر، جریان آب موجود در رودخانه بخصوص ایستگاههای تصفیهخانه و شاخکنار و شریفآباد و نیز پساب صنایع، فاضلاب شهرها و روستاهای مجاور، سبب شده است که گونههای حساس به آلودگی اکوسیستم حذف و گونههای مقاوم به آلودگی غالب شوند | ||

| The purpose of this study is to conduct a qualitative analysis of Zayandeh-rood River water using benthic invertebrate communities in fall 2017 to Spring 2018. To do so, we select 6 stations and 3 sediment samples were collected in each stations. Sediment samples were fixated and various animals were extracted from the samples and were grouped and identified according to fauna benthic identification keys were used for the identification of the sample. Finally, in spring 8 family belongs to 6 order; in autumn 11 family belongs to 7 order and in winter 6 family belongs to 4 order were identified. According to all indices, all stations and all seasons were in polluted category. Regarding the Zayandeh-rood drought, during the last decade, the flow of water in the river, especially the refinery stations and the Shakh-kenar and Sharif Abad, is practically the industrial wastewater, sewage of the cities and adjacent villages. For this reason, contaminated species in these ecosystems are species resistant to pollution. | ||
