Abstract
Climate change will have a profound impact on the surface hydrological cycle.This study analyzes the rainfall behaviour of the Danjiangkou Reservoir watershed from 1980 to 2018 based on three different precipitation datasets,with the Mann-Kendall trend test and cloud model.The analysis results indicate that prior to climate change the precipitation in the basin experienced a significant decreasing trend,with a reduction rate exceeding 10mm/a.After climate change,the decreasing trend of precipitation has been alleviated.The analysis results with cloud model reveal that climate change has led to a decrease in precipitation dispersion,and increase in concentration of precipitation,which leads to possibility of more extreme precipitation events in the future.The findings can provide scientific reference for water resources managers in the basin for water allocation work.关键词
