摘要
针对太湖水环境状态严重恶化,湖滨带生态系统功能日益下降的问题,以生态系统健康理论和熵权综合健康指数法为基础,构建了太湖水生态系统健康评价指标体系.综合评价结果表明,太湖湖滨带不同分区生态系统的健康状态得分分别为:北部梅梁湾区0.341;西部江苏沿岸区0.184;西南部浙江沿岸区0.741;东太湖区0.975;东部江苏沿岸区0.770.这表明太湖西北部水生态系统富营养化问题较为严重.
On account of serious deterioration of water environment and declining of lakefront ecosystem function of Taihu Lake.The purpose of this study was to establish a water ecosystem health assessment index system of Taihu Lake based on the theory of ecosystem and entropy comprehensive health index method.The results showed that different sub-regional ecosystem health status scores of Taihu Lake,which in northern Meiliang Bay area was 0.362,in western coastal of Jiangsu area was 0.183,in south-west coastal of Zhejiang area was 0.721,in East Taihu Lake area was 0.977,in eastern coastal areas of Jiangsu was 0.752.In conclusion,the water ecosystem eutrophication problem of Taihu Lake in northwest was even worse.
