中文摘要:根据作者所提坡面净辐射各分量的气候学计算方法,计算、分析了坡地净辐射在我国的分布特点,着重讨论典型站点坡地净辐射随坡向、坡度、纬度和季节的变化,并以南、北坡为例首次绘制、讨论了我国坡地净辐射的地理分布特点,揭示出在全国范围内南、北坡净辐射间的巨大差异,发现冬季北坡(坡度20°);净辐射负值区可达云贵山地和长江中下游这一非常有趣的新结果。
 
CLIMATOLOGICAL CALCULATION OF NET RADIATION ON SLOPES IN CHINA
Abstract:Based on the calculation of the components of slope net radiation (SNR) by the climatological methods proposed by Weng,analysis is done of the SNR distribution characteristics over China with the focus on changes in SNR as functions of orientation/slanting degree of slope, latitude and season from some representative stations. SNR on both the north and south sides is used to prepare for the first time the chart to illustrate its geographic pattern, indicating great difference in SNR between the two slopes over the mainland.It is of much interest to note that the winter SNR negative-value belt of 20° north slopes extends as far as the Yunnan-Guizhou Plateau and the middle and lower reaches of the Changjiang River.
