| 摘 要： | 利用红河流域及其周边地区23个气象站1961年~2005年的年平均气温资料,对红河流域的气温变化特征进行诊断分析,结果表明:近45年来,红河流域气温呈现明显的增暖趋势,无论是整个流域还是上游、中游地区其增温速度均高于全球增温速度。并且,红河流域的气温变化还存在明显的区域差异和季节差异,中游地区增温幅度大于整个流域和上游地区,全流域及上游、中游地区都表现为冬半年增温趋势和幅度大于夏半年。红河流域增温突变出现在20世纪80年代,显著性增温出现在90年代后,特别是1998年以后更为明显。

| Abstract: | Based on the annual average temperature data from 23 meteorogical stations in the Honghe river watershed and its surrounding areas during 1961 to 2005,the spatio-temporal variation characteristics of air temperature were analyzed.The result showed that,during the past 45 years,the air temperatures increased remarkably in Honghe River watershed,whether the entire basin or upstream and midstream areas,the warming rate is higher than the speed of global warming.Furthermore,the temperature change in the Honghe ... |
