摘　　要：柳园口引黄灌区位于河南省开封市,控制面积40 724 hm^(2),耕地面积30 900 hm^(2),为全国大型灌区之一,肩负着开封地区重要农业生产任务。文章以柳园口引黄灌区1981—2020年气象要素为研究对象,利用Microsoft Excel软件对灌区气候要素平均值进行统计分析,由分析得知,灌区多年平均气温呈上升趋势,降水出现下降趋势,该变化特征将对灌区的农业、水资源等方面产生重要影响。相关部门应加强灌区气候变化的监测研究,提高气候预测能力,以便更好地应对气候变化给灌区带来的各种挑战。Liuyuankou Yellow River Water Irrigation Area is located in Kaifeng City,Henan Province,with a controlled area of 40724hm~2 and cultivated land area of 30900 hm~2.It is one of the large-scale irrigation areas in China and is responsible for important agricultural production task in Kaifeng.This article takes the meteorological elements of Liuyuankou Yellow River Water Irrigation Area from 1981 to 2020 as the research object,and applies Microsoft Excel software to statistically analyze the average values of climate elements in the irrigation area.The analysis results indicate that the average temperature in the irrigation area has been on the rise for many years,while the precipitation presented downward trend.This change feature will have an important impact on agriculture,water resources,and other aspects of the irrigation area.The departments concerned should enhance monitoring and research on climate change in the irrigation area,improve climate prediction capabilities,so as to better address the various challenges brought by climate change to irrigation areas.
