Abstract: In recent years,with the increase of the people’s attention to the global climate change,the technology of retrieval of soil moisture based on remote sensing in the filed of environmental remote sensing has become one of the research focuses and cutting edges.By using remote sensing to retrieve the condition of soil moisture in the macro region,the study of vegetation growth conditions,crop growth and yield estimates,climate change and environmental response mechanism to provide basic basis,has important theoretical significance.In this paper,based on the understanding and analysis of the domestic and foreign research progress in Remote Sensing Inversion of soil moisture in the three aspects of visible light and near infrared,thermal infrared and microwave remote sensing method,summarized the main methods of remote sensing inversion of soil moisture,analyzed the principle and characteristics of each method,discussed the main technical questions that existed at home and abroad in this field,and look into the future possible prospect of the developing trend of soil moisture monitoring from four aspects.

Key words: soil moisture, retrieval model, optical remote sensing, microwave remote sensing
