摘　　要：地表辐射收支是一个重要的基本辐射参数，本文导得卫星可见光和红外波段测值与地表辐射收支的基本关系，据此利用ＧＭＳ静止气象卫星可见光和红外通道数值化资料和地面辐射收支观测资料，建立了几个由卫星资料估计地面辐射收支的模式，选择效果最佳的一种模式，通过内插方法求取全国辐射收支分布，回归效果与实测结果比较表明。The surface radiation budget is an important essential radiation parameter. In this paper, the basic relation between the measurements from the visible/infrared channel in satellite and the surface radiation budgets has been derived. According to this relation, some useful models of estimating the surface radiation budgets are obtained by the observational data from the visible/infrared channel in GMS satellite and the observational data from surface radiation budget stations. With the most excellent one of these models, the distribution of radiation budgets across China is obtained by the interpolation method. Compared to the actual observational data, this distribution has a better consistency with the actual results, which shows that this model is very effective in estimating the radiation budgets in China.
