| 摘 要： | 采用特定算法从全球遥感卫星数据库中提取局部地区自然地表的高度信息和地表覆盖类型，结合地表几何结构生成技术和地面红外辐射理论模型，充分利用先验知识研究了国内的喀什、嫩江和衢州三地的地表组分温度及其红外辐射特征。给出的方案为地表组分温度的反演提供了参考依据，同时也大大提高了遥感信息的利用率。

| Abstract: | Informantion on local natural terrain regions, such as the altitudes, land cover type and others, is extracted from the global satellite remote sensing database with a specially designed algorithms, The theoretical model for terrain IR radiation is developed based on the informantion and with assistances of terrain geometrical structure simulation technology, Based on the information obtained about the region Kashi, Nenjiang and Quzhou, surface temperatures and infrared radiations of the land surface in the regions are simulated. The retrieving method developed in this paper provides an alternative tool for the conversion of the satellite remote sensing data into land surface temperature. At the same time, it expands the application of the data. |
