摘　　要：太湖蓄泄关系是指太湖入、出湖水量和湖泊蓄水量之间的关系,决定了太湖水文和水情的基本特征。创建蓄泄关系指数,并结合湖水更新次数用以研究太湖蓄泄关系。基于2006年~2022年太湖水文资料,采用Mann-Kendall检验方法,分析太湖流域降雨量、太湖水位、太湖入、出湖水量及蓄泄关系的变化特征,讨论导致蓄泄关系变化的因素。研究表明:相关水文要素均呈显著增加趋势;太湖蓄泄关系得到显著性改善,在2014年附近发生突变,2014年后相较于以前,年平均蓄泄关系指数增加了0.05,年平均湖水更新次数增加了0.36;降雨量、沿江(江苏段)口门引排水量是导致太湖蓄泄关系变化的因素。Taihu Lake storage-discharge relationship refers to the relationship between the water inflow and outflow of Taihu Lake and the amount of water stored in the lake,which determines the basic characteristics of Taihu Lake's hydrology and water conditions.In this paper,a storage-discharge relationship index is created and used to study the storage-discharge relationship of Taihu Lake in combination with the number of lake water renewal.Based on the hydrological data of Taihu Lake from 2006 to 2022,the Mann-Kendall test is used to analyze the characteristics of rainfall,water level,water inflow and outflow,and storage-discharge relationship in the Taihu Lake basin,and the factors that lead to the change of the storage-discharge relationship are discussed.The study shows that,the relevant hydrological elements all show a significant increasing trend;the storage-discharge relationship of Taihu Lake is significantly improved,and a sudden change occurs near 2014;after 2014,the annual average storage-discharge relationship index increased by 0.05 and the annual average number of lake water renewal increased by 0.36 compared with previous period;the rainfall,the amount of water diverted from the gates along surrounding rivers(Jiangsu sections)are the factors leading to the changes in the storage-discharge relationship of Taihu Lake.
