A model for the surface albedo responding to SWC and LAI was developed, which showed a good performance in consistent between simulated and observed surface albedo.

反映土壤含水量和叶面积指数共同作用的地表反射率模型的模拟值与野外实测值具有较好的一致性。

The effect of the surface albedo is considered secondly as an error correction so as to obtain the net solar radiation at various surface albedos .

然后将地表反射率的影响作为误差项进行订正，从而得到各种地表反射率条件下的晴天地表太阳净辐射的计算方法。

Soil water content (SWC) and leaf area index (LAI) were the key factors affecting the surface albedo.

土壤含水量和叶面积指数是影响该区地表反射率的关键因子；

The results are helpful to improve the parameterization schemes of surface albedo in climate model and satellite remote sensing.

研究结果有助于改进气候模式和卫星遥感中高原地面反射率的参数化方案。
