摘　　要：利用生物多样性指标，从2007～2013年对南水北调徐州段张楼和蔺家坝控制断面底栖生物进行了水质的生物学评价，结果表明：虽然两个断面的物种数和生物密度在几年里有所波动，但总的看来都呈现出物种数增加和生物密度下降的趋势，也是两个断面的水质逐年好转的表现。The water quality in Zhanglou and Linjiaba in Xuzhou control section of the South-to-North Water Transfer Project from 2007 to 2013 was evaluated by biological diversity indicators. The results showed the tendency of species increased and biological density decreased in both of the two sites generally although the species and biological density fluctuate in the years. It indicated that water quality of the two sites improved year by year.
