摘　　要：为评价东江干流（惠州段）鱼类多样性,并监测其水质变化状况,根据该河段鱼类的调查资料及历史数据,编制了鱼类名录,并计算了鱼类平均分类差异指数和G-F多样性测度指数。结果显示,东江干流（惠州段）共记录近30多年来鱼类11目,29科,77属,94种,鲤形目鱼类占绝对优势；从物种水平看,研究的4个时间段鱼类物种多样性由大到小排序为Δ1＋981-1983、Δ2＋011-2012、Δ2＋007-2010和Δ2＋005-2007；从科属水平看,鱼类物种多样性由1981～1983向2005～2007减小,再向2007～2010增加,最后向2011～2012减小。其中,1981～1983的多样性最高,2011～2012的多样性最低。平均分类差异指数与G-F多样性测度指数均适宜于东江干流（惠州段）鱼类物种多样性研究。Based on the investigation data and the historical data of fish species during more than 30years in Huizhou Reach of Dongjiang River, the fish diversity was assessed and the changes of water quality was monitored. The species check-list of fish recorded-and-investigated was compiled and the average taxonomic distinctness and G-F diversity index were calculated. The cypriniformes were dominated and the total of 94species were devided into 77genera, 29families and 11orders. The order form large to small of the fish diversity was 1981 1983＋ -Δ , 2011 2012＋ -Δ , 2007 2010＋ -Δ2005 2007＋ -Δ . The diversities decreased from the 1981～1983to the 2005～2007, then increased to the 2007～2010, and finally decreased to the 2011～2012. Thereinto, the diversity was the highest in 1981～1983and the lowest in 2011～2012. The average taxonomic distinctness and G-F diversity index are fit to research the fish species diversity in Huizhou Reach of Dongjiang River.
