摘要：

为了及时准确地从遥感图像数据中反演出地表温度的变化，针对辽宁地区制定播种计划、确定种植结构等提供技术支持，选取辽宁省作为研究区，利用EOS/MODIS热红外遥感数据和FY-3/MERSI数据与相关的地面气象台站实测数据，建立地表温度反演模型。采用分裂窗算法中的两因素模型和普适单通道算法对辽宁省地表温度进行反演。通过对气象台站实测的地面温度值和反演的温度进行拟合来获取回归方程，再利用反演的温度值模拟真实地表温度。对比2种算法，得出分裂窗算法是更适合进行辽宁地区地表温度的反演方法。

Abstract:

In order to timely and accurately retrieve land surface temperature changes from the remote sensing image data, to develop planting plan for Liaoning region, determine the structure of cultivation and provide technical support, the author took the Liaoning Province as the test field, measured the ground surface data with the EOS/MODIS thermal infrared remote sensed data and relevant practical and established the land surface temperature retrieval model. Split window algorithm using two-factor model and universal single-channel algorithm, Liaoning Province, the surface temperature inversion. Meteorological stations measured by the ground temperature and the temperature inversion to obtain the fitted regression equation, reuse of the temperature inversion simulate the real surface temperature. Comparison of the two algorithms, the author derived split-window algorithm was more suitable for the surface temperature of the Liaoning region inversion.
