受梯级枢纽开发影响的汉江中游流量变化研究
Study on flow changes in the middle of Hanjiang River affected by cascade hub development
摘要
Abstract
In order to evaluate the changes of flow in the middle Hanjiang River,nearly 58 years of daily flow data of Huangzhuang Hydrology Station from 1965 to 2022 were selected,and the development time series of major water conservancy projects such as Danjiangkou Reservoir,Wangfuzhou Water Conservancy Project,Cuijiaying Avionics Project and Middle Route of South-to-North Water diversion project were analyzed.The study period was divided into the baseline period which was not disturbed by human activities and the 4 typical influence periods.Mann-Kendall non-parameter test method was used to analyze the characteristics of multi-year flow variation,and the range of variability approach(IHA-RVA)was used to analyze the flow indexes in different influence periods.The change of flow in the middle Hanjiang River was comprehensively evaluated according to the degree of hydrological change and deviation of each hydrological index.The results show that under the influence of Danjiangkou,Wangfuzhou,Cuijiaying,Yakou and Xinglong water conservancy projects,the flow of the middle Hanjiang River fluctuates in different degrees,and the overall hydrological change degree of 32 IHA indexes reach 47.46%~63.74%,which is judged as middle change.关键词
