摘要
Abstract
Based on meteorological data from 1968 to 2020 in the Daling River Basin,this article uses Matlab programming to calculate the comprehensive meteorological drought index,standardized precipitation index SPI,and precipitation anomaly percentage Pa for each station in each month.By comparing with the actual drought situation,the optimal evaluation index for the drought situation in the watershed is determined as the comprehensive meteorological drought index CI.The distribution law of drought in the Daling River Basin is systematically analyzed from the perspective of spatiotemporal changes.It is hoped that the research results can provide reference for flood control,drought resistance,and water resource management planning in the Daling River Basin.关键词
