| 摘 要： | 随着经济的快速发展，无锡市水环境质量发生了很大的变化。由于在太湖、五里湖等湖泊周围大规模围湖造田，水域生态环境和原有水系格局被破坏，五里湖、梅梁湖水质恶化，每10年下降一个等级，太湖水质总体上呈现富营养化状态。水环境变化在一定程度上导致了地面沉降的发生，有的地区地下水位呈加速下降的趋势，有的地区已出现多个地下水位降落漏斗，后者面积达220km^2。应该加快区域供水建设步伐，调整工业结构，加强对水资源的管理和调控。

| Abstract: | With the quick economic development, the water environment of Wuxi has changed greatly and has been seriously polluted. Lake inning for land reclamation at large scale in Taihu Basin and Wuli lake has given rise to a great change of ecological environment, original water patterns have been damaged, the water quality in Meiliang Lake and Wuli Lake decreased, and 2/5 area of Taihu Basin is eutrophication at present. Water environment change has led to land subsidence, the underground water in Qianzhou, Luoshe, Shitangwan has decreased very fast, and underground water funnels has reached about 220 km2. To control land subsidence, the industrial structure must be adjusted, regional water supply must be developed fast and comprehensive water management must be improved. |
