摘　　要：河流的水文情势变化驱动着河流乃至流域生态环境系统地发展。系统分析赣江上游桃江的水文情势变化,可为流域进行水资源综合利用及形成适宜的水文生态环境提供科学指导。基于1960—2019居龙滩水文站的逐日径流量实测资料,并结合降雨气候,运用线性回归、累积距平和趋势滑动平均和集中度等方法对径流演变进行趋势分析,最后采用IHA/RVA法系统分析了赣江上游桃江的水文情势变化。结果表明:人类活动对桃江流域流量改变影响显著;流域径流的集中度呈现显著下降,集中期呈现增加趋势,径流最大值推迟出现且年内分配更加均匀;变化后流量脉冲次数增加,流量上升率减少,下降率增多。桃江流域整体水文改变程度属于中等偏低,即流域处于较为良好的变化趋势。The hydrological situation of the river drives the river and the systematic development of ecological environment in rivers and even river basins. The system analysis of the changes in the hydrological situation of Taojiang River, which is located in the upper reaches of Ganjiang River, can provide a scientific guidance for comprehensive utilizing water resources in the basin and forming a suitable hydrological ecological environment. Based on the measured data of daily runoff from 1960 to 2019, combined with the rainfall climate, the methods of linear regression, cumulative anomaly, trend moving average and concentration were used to analyze the trend of runoff evolution. Finally, the IHA/RVA method was used to analyze the hydrological regime of Taojiang River in the upper reaches of Ganjiang River. The results showed: human activities had a significant influence on the change of discharge in Taojiang River basin;the concentration of runoffs in the basin was significantly decreased, and the medium-reducing trend was increased, and the maximum value of runoff was delayed and distributed more evenly during the year;after the change, the number of flow fluctuations was increased, the rising proportion of discharge was decreased, and the decreasing proportion was also increased. The overall degree of hydrological change in the Taojiang River basin belonged to the medium to low level, that is, the basin was in a relatively good trend.
