基于Landsat TM和OLI/TIRS数据反演了呼和浩特 区域的地表温度。经MODIS地表温度产品检验，反演结果的精度较好，平 均相对误差为5%，均方根误差为1.53℃(R=0.88)。研究结果表明，不 同类型地表的温度不同，最高值出现在建筑用地上，最低值出现在植被和 水体覆盖区域。地表温度与建筑用地、裸地和半裸地分布之间呈正相 关，而与植被分布呈负相关。建筑用地和裸地对地表温度的影响较大，而 半裸地和植被对其的影响则较稳定。

On the basis of the data from Landsat TM and OLI/TIRS, the Land Surface Temperature (LST) in Hohhot metropolitan area is retrieved. Compared with the MODIS LST products, the retrieved LST shows its good accuracy with an average relative error of 5% and a Root Mean Square Error (RMSE) of 1.53 ℃ (R=0.88, e=5%). The research result shows that the LST values of different types of Land Use/Land Cover (LULC) are different. The highest temperature appears in the building land and the lowest temperature appears in the vegetation and water coverage areas. LST is associated positively with the distribution of building land, bare land and semi bare land and is associated negatively with the distribution of vegetation. The building land and bare land have great influences on LST while the semi bare land and vegetation have more stable influences on LST.
