摘　　要：根据河南省17个气象站1965~2014年逐日降水量资料,采用滑动平均法、Mann-Kendall趋势检验法、旱涝分析法和气候倾向率法等方法对该省降水时空变化规律进行了分析,结果表明:近50年来,河南省降水量年内分配不均,主要集中在夏、秋两季;春、夏、秋、冬季的降水量均呈增加趋势,上升幅度分别为0.87 mm/10a,6.98 mm/10a,4.09 mm/10a,2.63 mm/10a;大部分地区降水日数呈减少趋势,降水日的日平均降水量呈增加趋势;年降水量和各季降水量在空间分布上均是由南向北或由东南向西北逐渐减少。According to the 17 stations daily precipitation data of Henan province from 1965 to 2014, using the slip averaging method, Mann-Kendall tendency test method, drought and flood analysis method and climate tendency method, it analyzes the precipitation spatial and temporal change rules. The results show that in recent 50 years, annual rainfall distribution of Henan province of is uneven. The rainfall mainly concentrates in summer and autumn season; The precipitation in spring, summer, autumn and winter showed an increase of 0.87 mm/10a, 6.98 mm/10a, 4.09 mm/10a, 2.63mm /10a.The number of precipitation days in most areas is decreasing, and the daily average precipitation of precipitation is increasing. The annual precipitation and the precipitation in different seasons are both from south to north or from southeast to northwest are decreasing.
