地表温度是检测地球环境变化的重要指标,将地表温度与气象观测资料相结合可以更准确地检测地表履被、土壤湿度及水分含量变化.利用MODIS数据对青海湖流域地表温度进行反演,将反演结果与实测0cm地面温度对比分析,显示反演的地表温度值与实测0cm地面温度值平均盖-1.05℃,在当前遥卷反演地表温度的误差之内.结果表明地表温度和气象观测资料相结合,可以用于监测地表温度的变化,进而建立偏远地区气候资源数据库.

Land surface temperature is one important index which can be used to detect the environment change of earth. It can detect the changes of land cover, soil moisture and moisture content accurately combining the land surface temperature and the weather observation data. The paper retrieval the land surface temperature of Qinghai lake basin by MODIS, study the precision by combining the weather observation data ,and provide doable evidence for building the weather database of Qinghai lake basin.
