中文摘要:本文在讨论日射站反射率资料应用和统计方法的基础上,利用全国日射站实测资料分析了地表反射率的影响因子及其时空变化特征,分别建立了地表反射率与积雪日数和气温的经验公式。还参考全国土壤和植被分布图,绘制并讨论了我国各季地表反射率分布图。
 
COMPUTATION OF SURFACE ALBEDO AND ITS DISTRIBUTION OVER CHINA
Abstract:Along with adiscussion on the application and the statistical processing of albedo data, factors influencing the value of surface albedo and its areal and temporal distribution over China are analyzed, data being available from 60 actinological stations. Two empirical formulas for estimating mean monthly albedo, taking into account snow cover and temperatures respectively. Mean albedo charts of China for significant months representing the four seasons are constructed, with the characteristic distribution of types of soil and vegetation being considered.
