摘　　要：2009年9月和2010年8月依次对浙江省4座大中型水库水源地的浮游生物现状进行了调查,采用浮游生物完整性指数(P-IBI)评价方法对数据进行统计分析。经过对22个备选参数的筛选,构建了以藻类密度、藻类平均体重、藻类生物多样性指数、浮游动物/浮游植物、潜在产毒藻类丰度、不可食藻类密度比为入选参数的浮游生物完整性评价体系;进一步利用该评价体系对4座水库的水生态健康程度进行分级评价。结果表明,4座水库的P-IBI评价分值依次为1.216、5.157、3.304和3.542;P-IBI等级依次为差、优、良、良。评价结果能够较好地反映浙江省水源地的富营养化、藻类水华风险程度等水生态健康状况。Investigation study on plankton population was conducted during 2009 and 2010, and the data were ana- lyzed with an evaluation method of Planktonic Index of Biotic Integrity （P-IBI）. According to the research data, an evaluation model of P-IBI composed of 6 metrics was established. Furthermore, ecological health statuses of four reservoirs were also evaluated. Results showed that the P-IBI scores of four reservoirs were 1. 216, 5. 157, 3. 304 and 3. 542 respectively; the health statuses were poor, excellent, good and good correspondingly. Results also indi- cated that the P-IBI evaluation system can reflect the health status of aquatic ecosystem of water resources in Zhe- jiang Province.
