引滦工程上游浮游动物及其水质评价

对引滦入津输水工程沿线上游水域进行浮游动物种类区系组成、生物量及分布的调查研究。结合历史资料和国内相似水体研究结果并辅以生物多样性指数的分析，对调查水域进行了水生态环境质量评价。结果表明，调查水域整体上可初步划定为贫营养型向中营养型过渡类型，水质状况尚好。但调查水域下游的潘家口和大黑汀水库网箱养鱼的发展一定程度上影响了局部水域，由此引起的水体富营养化趋势应引起足够的重视。

Zooplankton and Bioassessment of Water Quality in Upper Waters of Yinluan Project

Current fauna, biomass and distribution on zooplankton in the upper water of the Yinluan Project are investigated and studied. A biodiversity Index analysis is performed. Based on the present study and referring to the historic investigated data and the information from the studies on allied domestic water bodies, an ecological and environmental status of the investigated area is assessed and evaluated. The research result suggests that the water quality of the area can be delimited to poor to mesotrophic type. But more attention should be paid as the eutrophication tendency caused by box aquaculture in Panjiakou and Daheiting Reservoirs.
