摘　　要：基于1986—2018年期间环太湖水文巡测资料,分析了环太湖及主要水资源分区出入湖水量的时空变化趋势。研究结果表明,环太湖入湖水量历年变化整体呈增加趋势,在2007年前、后2个时期年均入湖水量增加了29.9亿m^(3)。太湖入湖水量增加主要集中在湖西区,浙西区入湖水量变化则相对稳定,但在年内水资源调度期时浙西区入湖水量表现出减少的趋势。受太湖水位上涨影响,环太湖出湖水量也表现出增加的趋势,这主要反映在流域下游的阳澄淀泖区和杭嘉湖区出湖水量的增加。此外,受供水调度影响,太浦河出湖水量也表现出增加的趋势,特别是在金泽水源地投入使用以后,水资源调度期太浦闸日均下泄流量增幅明显。Based on the hydrological data around Taihu Lake from 1986 to 2018,the spatio-temporal variation of water inflow and outflow in Taihu Lake and main water resources zones were studied.The results show that the water inflow of Taihu Lake has increased significantly over the years,the average annual inflow increased by 2.99 billion cubic meters in two periods before and after the year 2007.The increase in the inflow of Taihu Lake was mainly concentrated in the western area of the lake,while the variation of inflow from the water resources zones of Zhexi was relatively stable,but the water inflow from the water resources zones of Zhexi showed a decreasing trend during the water resource dispatching period of the year.Affected by the rising water level of Taihu Lake,the outflow of Taihu Lake also showed an increasing trend,which was mainly reflected in the increase of outflow from the water resources zones of Yangchengdianmao and Hangjiahu in the lower reaches of Taihu basin.In addition,with the increasing water supply,the outflow of Taipu River also showed an increasing trend,especially after the water source of Jinze was put into use,the daily discharge of Taipu sluice increased significantly during the water resource dispatching period.
