摘要
对引滦入津工程沿线上游水域进行浮游植物种类区系组成、现存量(密度、生物量)及分布等内容进行了调查研究,并结合历史资料和国内相似水体研究结果的分析,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中营养型,水质状况尚好。但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。
The current fauna,standing crop (density and biomass) and distribution,ect.on phytoplankton in the upper water of the Yinluan Project are investigated and studied.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 mesotrophic type and that the water quality is good.However,the net-box fish farming in Panjiakou and Daheiting reservoirs in the downstream has somewhat affected local waters,and the resulted eutrophication trend should be paid sufficient attention to.
