英文摘要	Surface soil moisture (SM) plays a decisive function during the grassland degradation and restoration process. In this paper, a surface soil moisture retrieval model in desert steppe area with improved spatial resolution is established using diurnal temperature range (DTR) and Normalized Difference Vegetation Index (NDVI). The model integrates land surface temperature (LST) at daytime and nighttime respectively derived from Landsat8 and MODIS images to improve the spatial resolution of soil moisture from 1km to 30m. The results are validated by in situ measurements from Frequency Domain Reflectometry (FDR) in study region, and the root mean square error (RMSE) is 1.3919. Compared with the MODIS-DTR, the Landsat-MODIS DTR improves the accuracy and the spatial resolution of soil moisture retrieval.
