用综合生物指数法评价水质

针对单项生物指数评价水质的片面性不确定性，提出了用综合生物指数法评价水质。实验结果表明，该方法在综合各种生物指数评价结果的基础上，能对某一水体水质作出明确的评价结论，且与用理化监测结果评价水质的结论相吻合。

To Evaluate Water Quality with Comprehensive BiologicalIndex

Because of the one sidedness and uncertainty of single biological index to evaluate water quality, comprehensive biological index was suggested. The experiment result showed that it can reached a definite evaluation result on the basis of synthesizing all kinds of evaluation results of single biological index. And result was same as the result with physical and chemical methods.
