摘　　要：使用Landsat-5 TM数据推算金塔地区地表反射比、地表温度、地表净短波辐射及净全辐射。将反演值与观测值进行对比,结果表明:地表温度、地表反射比、地表净短波辐射、净全辐射反演相对误差分别小于6%、17%、12%、3%。结果基本可信,其频率分布也基本反应了当地各参量的实际分布情况。Landsat-5 TM data were used to calculate land surface parameters over Jinta area such as： surface reflectance, surface temperature, net solar radiation and surface net radiation. The retrieval were compared with the observed data, the results show the relative error of surface reflectance, surface temperature, net solar radiation and surface net radiation is less than 6%, 17%, 12% and 3% respectively, and the frequency distribution describes the practical situation of each parameter exactly.
