摘要:
利用黑龙江省28个气象站点1959—2010年逐日降水资料，采用气候倾向率、ArcGIS中的反距离加权插值等方法分析了黑龙江省不同级别降水日数、降水量和降水强度的气候特征及变化趋势。结果表明：近52a来，黑龙江省年平均降水量呈微弱的减少趋势，雨量的减少主要是由于夏季微雨和小雨雨量显著减少；降水强度呈显著减弱趋势，主要是源于微雨和小雨降水强度的减少；年雨日数及四季（夏季除外）的雨日数均呈增加趋势。雨日的增加主要是由于微雨、小雨及中雨日数显著增加；降水量空间分布特征总体表现为中部最多，南部其次，西部和北部相对较少。
Abstract:
Based on daily precipitation data of the 28 weather stations in Heilongjiang Province during the period from 1959 to 2010,the climatic characters and changing trend of rainfall days,rainfall amount and rainfall intensity in Heilongjiang Province were analyzed by using the methods of climate trending rate and Inverse Distance Weighted interpolation method.The results showed that the annual precipitation slightly decreased and the decrease of rainfall dominantly resulted from the decline in trace and light rainfall in summer.Rainfall intensity showed a significant decrease trend,what’s more,the decrease of intensity was mainly dued to the decline of trace and light intensity.The number of annual and seasonal (except summer) rainfall days increased while the increase of rainfall days owed to the significant going up in trace,light and moderate rainfall days.Spatial distribution characteristics of the precipitation indicated that precipitation of the central area was the highest,followed by the southern area,while precipitation of the west and north was relatively less.
