【摘要】 通过对环太湖1986~2010年水文巡测资料的整理,使用分区域分阶段的对比分析方法,分析太湖入出湖水量变化情势及其成因。分析表明,太湖入湖水量总体呈上升趋势,而流域降水量总体呈下降趋势,湖西区、望虞河入湖水量增加明显,而杭嘉湖区和武澄锡虞区自2000年以来入湖水量下降明显;太湖出湖水量与入湖水量变化基本一致。研究还发现,太湖各区域入出湖水量变化不仅与区域降水量有关,与"引江济太"等环境治理工程更加密切。更多还原

【Abstract】 Based on the hydrologic data of Taihu Lake Basin,the changing condition and causes of the inflow and outflow of Taihu Lake from 1986 to 2010 were studied through comparison and analysis by sub- regions and stages. The analysis results show that the inflow of Taihu Lake generally has been increasing,while the basin annual precipitation has been declining. The inflow from the western lake area and Wangyu River increases significantly,while the water from Hangjiahu area and Wuchengxiyu area has significantly decreased since 2000. The changes of inflow and outflow basically keep consistent. The research also indicates that the change in inflow and outflow around Taihu Lake is not only related with regional precipitation,but also closely related with some environmental managing projects such as the Project of Water Diversion from Yangtze River to Taihu Lake.更多还原
