| 摘 要： | 从能量传输方程入手，推导出地表入射辐射通量密度的简便计算公式； 根据反照率定义，提出基于能量的地表反照率反演新方法。用鄱阳湖地区TM遥感数据试验，其误差为4.91%。该方法不但简便易行，所需野外数据较少，物理意义明确，而且省去了窄波段反照率的计算过程，是一种遥感反演区域反照率的好方法。

| Abstract: | This paper deduces a simple formula for computing the incidence radiant flux density. Based on the definition of albedo, the authors put forward a new method of surface albedo inverse model. The TM data of the Poyang Lake were used to make a test, and the average relative error was only 4.91%. The method is easy to utilize, and it only needs spectral data of two different kinds of land covers. In addition, it doesn’t need the albedo computation of narrow wavebands. The method proves to be a good means for inversion of surface albedo. |
