摘要
Abstract
For the Sustainable use of water resources and reasonable operation of reservoir,the inflow variation characteristics and influencing factors,which include inflow inter-annual variation characteristics,changing trend,precipitation change,and the impact of human activities,were analyzed based on historical records from Zhangwu Reservoir During 1973-2022.Linear trend analysis,①Moving-average model,Cumulative anomaly method,R/S analysis,and double mass curve for annual rainfall stream flow were used comprehensively in the study.The results showed that the multi-year change of inflow of Zhangwu Reservoir had a distinctive decreased tendency at 3.1 million m3 per year during 1973-2022.②The Hurst index was 0.7892 for Zhangwu Reservoir which indicates that the decreasing trends would continue in the future.③Human activities were the main reason of inflow descending in Zhangwu Reservoir which are high to 94.27%since 2006.关键词
