摘　　要：开展了青浦区西部地区大型底栖无脊椎动物调查,基于底栖生物完整性指数(benthic index of biotic integrity,B-IBI)评价体系,评价了区域水生态健康状况,分析了B-IBI指数与水质指标及相关指数的关系,探讨了B-IBI指数在湖荡地区的适用性.结果表明:研究区域水生态健康状况总体良好,健康及亚健康样点占比67.7%,湖泊及湖荡区域的B-IBI指数多优于河流;B-IBI指数对水体有机污染、富营养化有较好的指示作用;各评价指数之间具有显著相关性,但B-IBI指数与丰富度指数、多样性指数评价结果有所差异;B-IBI指数在湖荡区水生态评价中具有很好的适用性.In this study,a benthic macroinvertebrates survey was conducted in the western Qingpu District.The Benthic Index of Biotic Integrity(B-IBI)was used to assess the regional water ecological health.The relationship between B-IBI and water quality indicators,including related indices,was analyzed,and the applicability of B-IBI in lake-swamp areas was explored.The results showed that the water ecological health of the study area was good overall,the proportion of healthy and sub-healthy sample sites was 67.7%,and B-IBI indexes of the lake-swamp areas are better than those of rivers.The B-IBI index can effectively indicate organic pollution and eutrophication in water bodies.In addition,a significant correlation among the biological indices was found,despite the differences in evaluation results.We conclude that the B-IBI index has good applicability for the water ecology assessment of lake-swamp areas.
