【摘要】 湖泊大型底栖无脊椎动物能对自然和人为活动导致的水和沉积物质量变化做出可预测的响应,因此利用底栖动物作为湖泊生态环境监测的生物指标和进行系统健康度量的生物指数已经得到了广泛的认可。本文比较分析了几种常用的和正在发展的湖泊生态系统健康和生态环境质量状况评估的底栖动物指数,包括指示物种、生物多样性指数、HBI指数、B-IBI指数,总结了这几种生物指数的应用和特性,探讨了底栖动物指数在实际应用中可能存在的问题和解决的办法,以期为我国湖泊生态系统健康评估工作提供参考。更多还原

【Abstract】 Abundant researches have demonstrated that benthic communities respond relatively rapidly to natural and man-induced changes in water and sediment quality,so benthic communities are used frequently as bio-indicators of lake monitoring and biotic indices of assessing the lake ecosystem health.Several common and developmental biotic indices for assessment on the lake ecosystem health and ecological status are reviewed and analyzed,including indicator species,diversity indices,Hilsenhoff biotic index(HBI) and the benthic index of Biotic integrity(B-IBI).The paper summarizes the main application and properties of each index, and provides some illustrations and comparative analysis.At last,existent problem and resolvent in the practical application of benthic indices are discussed.Therefore we presume upon providing reference to our assessment of the Lake Ecosystem Health.更多还原
