着生藻类群落在黄浦江水质监测中的应用

在分析黄浦江不同断面水质理化指标的基础上，从着生藻类群落中的优势种、两类多样性指数等参数的变动状况，分析不同断面的水质对参照点着生藻类群落的影响。生物多样性指数、硅藻指数与水质级别关系分析表明，除部分次数的实验相关性不好外，基本能反映水质相对级别的差异，且季节性数值差异较小。研究指出：在了解参照点水质的情况下，可以通过对参照点藻类群落的室内测试来定性或者定量监测同一河流水质生态环境的综合状况，较之野外生态调查，可以节省大量的工作量。

Application of Inserted Agal Community to Water Quality Monitoring in Huangpu River

Based on physico-chemical indexes of Huangpu River reaches, from the changes of dominant of inserted algal community and diversity etc. to analyze the effect of different reaches water quality on the reference point inserted algal community. Analysis on the relation between biological diversity, diatoms indexes and grade of water quality showed that the deviation of water quality grade basically reflected the relative deviation of water quality and with little deviation of seasonal value. The study indicated that on understanding the water quality of reference point, it could be qualified or quantified through lab. test on algal community of reference point to monitoring the same river water quality ecological comprehensive situation.
