| 摘 要： | 选取了河北省三大主要洼淀为研究对象,分季节采集水样和表层底泥,做水质和硅藻分析.运用综合营养指数法(TLI)定量评价(白洋淀、衡水湖、永年洼)富营养状况,定性分析了其富营养及沉积硅藻组合对水质的响应.研究结果表明:河北三大洼淀水质均呈现富营养状态,硅藻组合对其具有较好的响应.沉积硅藻的持续研究,将为湖泊的富营养治理提供科学依据.

| Abstract: | This research selects three major depression lakes （Baiyang Lake, Hengshui Lake, YongNianWa） as the research objects in Hebei province. We collect water samples and surface sediment in different seasons to analyze water quality and diatom then use TLI to evaluate the nutritional status of the lake in quantitative method and analyze the influence of eutrophication on water quality in qualitative method. The results show that. three major depressions lakes showed eutrophication, diatoms combination has a good response to it. The research of sedimentary diatoms could provide scientific basis for the management of eutrophication of the lake. Finally, we try to put forward some constructive proposals on eutrophication on the basis of the research. |
