摘要

於1979年4月至6月之間，對淡水河流域之二十一個採集站進行水生物調查工作。水生物調查項目包括水中微生物（浮游動物類、藻類）、底棲動物（水生昆蟲、環節動物、淡水螺），以及游動性大型動物（魚類、蝦類）之調查。以調查所得之生物資料依生物指標（Biological indicator）、生物指數（Biotic index）、群落變異指數（Community diversity index）來評估淡水河流域各河段的水質污染等級，並由水生物資料瞭解目前淡水河流域的生物相，作為河川污染程度減輕或加重的直接評鑑依據。

並列摘要

This research work is in association with the project of ”Tan-Shui River Basin Water Pollution Control and Management Planning”, executed by Water Resources Planning Commission, Ministry of Economic Affairs. It has been proceeded with inspection of aquatic life at twenty-one collect stations along the Tan-Shui River Basin from April through June in 1979. The inspection of aquatic life' concerned in this research included microorganism (zooplankton, algae), bottom fauna (benthic insect, Annelida, Molusca), and swimming aquatic organism (fish, crayfish). Based on the biological data obtained in this inspection, we may assess water pollution degrees in each zone of the Tan-Shui River Basin by means of Indicator organism, Biotic index, Community diversity index, and thereby we may understand the present Biota in the river. Meanwhile it can provide direct evaluation standardization for future improvement of the river pollution.
