Analysis of Runoff Variation Trends and Characteristics in the Langchuan River Basin
摘要
Abstract
Taking the typical hydrological stations in the upper reaches of the Langchuan River Basin as the research object,the Mann-Kendall method and the cumulative anomaly method were adopted to con-duct an in-depth analysis of the runoff trend.In this paper,the runoff data observed by four hydrological stations,namely Hexikou Station,Baimaoling Station,Yangshanling Station and Shijie Station,in the Langchuan River Basin over nearly 50 years(1970-2020)are selected and analyzed.It is found that the var-iation of water flow in the Langchuan River Basin is mainly comprehensively affected by factors such as precipitation,land use change and soil and water conservation conditions.The research results show that since 1970,the runoff volume of the Langchuan River Basin has generally shown a decreasing trend.Espe-cially after 2000,the downward trend was obvious,and there was a sudden change point in 2015.This re-search method provides a reference for the basin water resources management in the southern Anhui re-gion.关键词
