近年来，随着人们对全球气候变化的逐渐重视，环境遥感领域中的土壤水分遥感反演技术已成为研究热点和前沿之一。通过对区域宏观土壤水分进行遥感反演，对于研究植被生长状况、农作物生长发育及产量预估、气候变化及环境响应机制等提供基础依据，具有重要的理论意义。在广泛了解和分析国内外土壤水分遥感反演研究进展的基础上，分别从可见光－近红外法、热红外法和微波遥感法3个方面总结和归纳了目前土壤水分遥感反演的主要方法，分析了各方法的原理与特点，讨论了国内外在该领域研究方面存在的主要技术问题，最后从4个方面对基于遥感技术的土壤水分反演研究进行了展望。

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 sens-ing has become one of the research focuses and cutting edges.By using remote sensing to retrieve the con-dition 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 re-mote sensing inversion of soil moisture,analyzed the principle and characteristics of each method,dis-cussed 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.
