2010年5月至11月对西泉眼水库鱼类资源进行了系统调查,共调查鱼类3095尾,鉴定出鱼类种类30种,分别隶属于6目11科30属,其中鲤科鱼类21种,占全部种类的70%。并利用Pinkas相对重要性指数（IRI）、Shannon-Weaver多样度指数（H′）和Pielou均匀度指数（J′）三种分析方法,对水库鱼类多样性特征进行了分析。西泉眼水库鱼类Pinkas相对重要性指数（IRI）分析得出,中小型鱼类优势种有3种,分别是池沼公鱼（Hypomesus olidus）、餐（Hemiculter leucisculus）、蛇（Saurogobio dabryi）;放养鱼类优势种以鲢（Hypoph-thalmichthys molitrix）、鳙（Aristichthys nobilis）为主。Shannon-Weaver指数（H′）值在0.1373~0.2129之间,Pielou指数（J′）值在0.0404~0.0626之间。总体来说,西泉眼水库鱼类物种多样性偏低,稳定性不高。最后提出了西泉眼水库鱼类物种多样性保护建议。

This paper systematically invested the fish resources included 3095 individuals of the Xiquanyan Reservoir and identified 30 fish species,which belonging to 6 orders,11 families and 30 genera.And the carp families had 21 species and occupied 70% of the total number.And also analysis the fish diversity of the reservoir by three methods such as Pinkas relative importance index,Shannon-Weaver diversity index and Pielou evenness index.The Pinkas relative importance index about Xiquanyan Reservoir（IRI）draw a conclusion that the middle and small fish had three dominant species,which including Hypomesus olidus、Hemiculter leucisculus and Saurogobio dabryi;the dominant species of the stocked carps were Hypophthalmichthys molitrix and Aristichthys nobilis.The Shannon-Weaver index value（H′）varied from 0.1373 to 0.2129 and the Pielou index value varied from 0.0404 to 0.0626.General,the fish diversity in Xiquanyan Reservoir were in low level and the stability was bad.Finally,the paper proposed the protective suggestions of fish species diversity in Xiquanyan Reservoir.
