摘　　要：劈窗算法是目前热红外遥感反演地表温度最常用的方法,根据Coll提出的劈窗算法建立基于MODIS适用干旱/半干旱区地表温度反演算法,并用同期的LP DAAC发布的MODIS地表温度产品和相应的53个气象站点的实际观测数据进行验证。通过分析,模型的反演精度与MODIS地表温度产品的反演精度相当,与气象观测数据相一致,反演精度较好,能够较精确地反演干旱/半干旱地区地表温度的时空变化特征。The Split-Window Algorithm is the most commonly method for Land Surface Temperature （LST） retrieval with the Remote Sensing of Thermal Infrared. The paper build a Split-Window Algorithm based on the MODIS which is suitable for LST retrieval in Arid / Semi-arid regions and verify them with the same period of MODIS Land surface temperature products which is released by LP DAAC and the corresponding 53 meteorological observations data. By analyzing the accuracy of this model is the same as the accuracy of MODIS LST products and the meteorological observation data. The results can show LST characteristics of spatio-temporal changes in Arid/Semi-arid regions.
