| 摘 要： | 根据作者提出的地表净辐射各分量的气候学计算方法，计算出青藏高原及其周边地区１７３站的净辐射和其各分量的年，月平均通量密度，并分析其地理分布特征。指出高原主体为总辐射，有效辐射的高值区，地表净辐射场在冬，夏季有较大差异。冬季为一弱正值区，相对低中心呈块状散布在祁连山区等几个地区；夏季因夜雨及地表湿润的缘故，高原大部地区的地表净辐射反有加强。各地净辐射年变化基本形式与总辐射相似。有效辐射年变化一般呈双

| Abstract: | In terms of the climatological methods for calculating components of surface net radiation (SNR) proposed by Weng et al. (1988),annual and monthly mean flux densities of SNR and its components at 173 stations over the Qinghai-Xizang Plateau and its surroundings are computed and their geographical distribution features are analyzed. Results show that the main part of the highland is marked by a high-value zone of total and effective radiations and great difference exists in the SNR patterns between winter and summer. In winer a weak positive-value zone is displayed with a set of relatively low-value centers distributed in groups over the Qilian mountains and some other places,while summer SNR gets intensified in much of the Plateau on account of nocturnal rain and thus very moist ground. Besides,annual variations of SNR are basically similar to those of total radiation for all these stations,and effective radiations show,in its yearly change,a bi-peak pattern with the peaks (valleys) in spring and autumn (winter and summer). |
