中文摘要：

介绍了基于底栖动物的3类广泛应用的水质生物评价参数：Saprobic指数、BI指数、群落多样性指数,并结合它们在水质和水资源管理中的应用现状分析了各指数的优缺点。Saprobic指数和BI指数已是欧盟成员国及美国等国重要的水质生物评价指数,中国的水质生物监测技术规范中尚缺乏类似的生物指数。分析了中国开展BI指数水质生物评价研究的现状,探讨了中国建立BI指数评价标准与规范的研究基础、不足、应用前景和今后的研究建议。同时指出,目前的研究重点是底栖动物耐污值计算和BI指数水质基准。

英文摘要：

We reviewed the history and development of three widely used indices of water quality bioassessment with benthic macroinvertebrate：Saprobic Index,Biotic Index（BI）and Shannon-Wiener diversity index,and critically evaluated each of them according to their current applications in water quality and resource management.The Saprobic Index and Biotic Index were the key indices of national protocols of water quality bioassessment in EU member states and USA,however,no such indices were used in national protocol of water quality bioassessment in China.The present statues of studies on the BI in China were analyzed,and the achievements,gaps,perspective and research efforts in building up a national protocol of water quality bioassessment using BI were discussed.We suggested that the current key research points of BI were the calculation of tolerance value of benthos and BI criteria.
