摘　　要：分析了太子河流域大型底栖动物群落结构,采用大型底栖动物Chandler生物指数、Shannon-Wienner多样性指数、BMWP-ASPT记分系统、BI指数,对2015年度平水期太子河流域进行了水质生物评价,对以上4个指数的结果进行了Pearson相关性分析,讨论了各生物指数的适用性。将BI指数的评价结果与理化结果进行了比较分析。结果表明:BI指数更适于太子河流域开展水质生物评价。In this paper, the community structure of macrozoobenthos in Taizi River Basin was analyzed. Chandler biotic index of macrozoobenthos, Shannon-Wienner diversity index, BMWP-ASPT scoring system and BI index were used for biological assessment of the water quality of Taizi River Basin at its normal level in 2015. Pearson correlation analysis of the results from the above four indices was performed and applicability of each biological index was discussed. The assessment results and physiochemical monitoring results were compared, indicating that BI index was more suitable for biological evaluation of the water quality of Taizi River Basin.

关 键 词：群落结构 水质评价 指数的适用性
