摘　　要：2014年5月在洮滆水系长荡湖、滆湖和竺山湖布设12个监测点,共采集浮游植物7门109种,平均藻密度为3.94×10~7L^(-1)。Shannon-Wiener多样性指数、Margalef丰富度和Pielou均匀度指数的变化范围分别为0.98~4.18、1.04~3.54和0.18~0.75。上述3种指数和群落优势类群的综合评价结果表明,3个湖泊都处于富营养化状态;12个监测点中S1和S9水质状况最好,S10和S8水质状况最差;3个湖泊评价结果为长荡湖优于滆湖,滆湖优于竺山湖。Phytoplankton assemblages were sampled at 12 sites in three Lakes of Taoge River System in May2014. 109 taxa（ there-after species） were identified. The mean algal density was 3. 94 × 10^7 L^-1. ShannonWiener index,Margalef index and Pielou index of phytoplankton community varied in 0. 98 - 4. 18,1. 04 - 3. 54 and 0. 18 - 0. 75,respectively. The assessment results of the three indexes showed that the three lakes were all in eutrophication status. Among the 12 monitoring sites,S1 and S9 were the best in water quality,while S10 and S8 were the worst. The ecosystem condition in Changdang Lake was better than that in Ge Lake,and Ge Lake was better than Zhushan Lake.
