摘要
地表特征和下垫面物理性质在时空分布上的差异 ,造成地表能量分布的不均。地表积雪由于其分布广、反照率高、季节性强等特点 ,对局地气候乃至全球气候变化都具有深远的影响。遥感动态监测地表特征的变化和反演大面积反照率是一种实际有效的技术手段 ,该文应用遥感技术 ,分析研究了我国地表积雪分布和反照率的动态变化。
Different land surface feature and physical characteristics cause anisotropy energy distribution. They influence on regional and global climate change because of snow wide distribution, high albedo and continuous seasonal change. Remote sensing which monitors the change of land surface feature and derives regional albedo is an effective measure. In this paper, we study dynamic distribution of snow and dynamic change of albedo through remote sensing technology.
