摘要
通过调查苏州市太湖湖体及重点通湖河道初级生产力、浮游生物、底栖动物的结构和资源状况,评价太湖湖体水生态环境质量。结果表明:以上水体的水华爆发风险较低,各调查点位浮游动物、浮游植物、底栖动物密度分布范围分别为180.2~6905.9 ind./L,1.392×10^(6)~9.342×10^(7)L-1,280~4080 ind./m^(2);Shannon-wiener多样性指数均处于“轻污染~中污染”;浮游藻类与底栖动物质量指数评级为“中~一般”,综合营养状态指数评级为“良”;太湖湖体的水生态环境质量指数评级为“中”,需进行生态修复。
The primary productivity,the structure and resources of plankton and benthic fauna of Taihu Lake and key channels were investigated,and the water ecological environment quality of Taihu Lake was evaluated.The results showed that:the risk of cyanobacteria bloom in the above water was low,and the density distribution of zooplankton,phytoplankton and benthic fauna was 180.2~6905.9 ind./L,1.392×106~9.342×10^(7)L^(-1),and 280~4080 ind./m^(2),respectively.Shannon-wiener diversity index is in"light~medium pollution".The quality index of planktonic algae and benthic fauna was rated as"medium to average",and the comprehensive nutritional status index was rated as"good".The water ecological environment quality index of Taihu Lake is rated as"medium",and ecological restoration is needed.
