利用河南省110个观测站1965-2009年降水数据,采用空间分析和时间序列分析相结合的方法,对河南省年降水和四季降水以及不同降水界限的年代变化进行了时空演变特征分析并进行了0.05的显著性检验,结果表明：近45 a河南省年降水呈弱上升趋势,不同降水界限范围具有较明显的年际变化特征。从时间分布上看,春季与冬季变化趋势相似,都呈弱增加趋势;夏季呈显著增加趋势;秋季呈显著减少趋势。从空间分布上看,春季安阳西北部降水增多趋势显著,其他地区无论是降水增多或是减少均不显著;夏季全省大部地区降水增多,其中周口和平顶山两地区降水增多趋势显著;秋季大部地区为降水减少趋势,其中南阳、信阳两地区降水减少显著;冬季,全省大部分地区降水增多,但增多趋势不显著。

By using precipitation data of 110 observation stations in Henan f rom 1965 to 2009,combing with spatial analysis and time series analysis,the ti me-space evolution feature of annual precipitation,seasonal precipitation and a nnual variety of different precipitation boundary was analyzed,the 0.05 test of significance was made at the same time.The results showed that the annual prec ipitation had a weak anabatic trend and the annual variety feature of different precipitation boundary was obvious.From the view of temporal distribution,the trends were similar in spring and in winter,which were weak enhancive trends.W hile they were distinct increase and decrease in summer and autumn respectively. From the view of spatial distribution,in spring,the precipitation trend was n either distinct increase nor decrease except in northwestward of Anyang in where the trend was distinct increase.In summer,precipitation of most places increa sed especially in Zhoukou and Pingdingshan.On the contrary,in autumn,precipit ation of most places decreased especially in Nanyang and Xinyang.In winter,the trend was increased but not distinct.
