摘　　要：以长江中下游13个浅水湖泊周年季节性湖沼学调查所获得的水质生物评价数据为基础,通过指数与环境因子的相关分析,指数值的分布范围分析,以及判别能力分析对其进行筛选,确定了Shannon-Wiener指数、Margalef指数、BI指数3个对水质判别较为敏感的底栖动物生物指数,并采用分位数法确定其水质评价分级标准。应用此3种评价指数对长江中下游13个湖泊进行水质判别,3个指数评价的结果基本吻合,且生物学评价结果和化学评价结果较为接近,属中度污染以上的湖泊,其营养状态均达到了富营养化水平。该评价指数及其评价标准适用于评价长江中下游地区浅水型湖泊的水质状况。The study made research on the selection of the suitable biological index based on the seasonal limnological data of 13 shallow lakes along the mid-lower Yangtze River.Through analysis of correlation between biological index and environmental metrics,metric distribution and its ability to identify,we selected three sensitive metrics of Shannon-Wiener index,Margalef index,BI index for bio-assessment.Furthermore,the study employed metrics distribution to establish assessment criteria and made bio-assessment on the 13 lakes along the mid-lower Yangtze River.The study indicated the consistency of the three biological assessment of 13 shallow lakes along the mid-lower Yangtze River.The study also indicated the consistency of biological and chemical assessments.The trophic states of these lakes which were more than moderately polluted by biological assessment reached to the eutrophic level.These assessment indexes and criteria are suitable for use in the shallow lakes along the mid-lower Yangtze River.
