摘要

Based on the monitoring data of precipitation and runoff series from 1953 to 2013 and groundwater exploitation from 1977 to 2013 in Jinghui Irrigation Area,especially the evolution of water resources during the growth period of main crops,the trend test of precipitation and runoff series was carried out by using Spearman rank correlation test and R/S analysis.The results showed that the annual mean precipitation and runoff and the growth period of main crops showed a downward trend,and the changes in the future were similar to those in the past;the amount of groundwater exploitation has not changed much,which is about 150 million m^3.The research results can provide scientific basis for efficient utilization and reasonable allocation of water resources in irrigation area,and provide technical support for the development of modern agriculture.
