对国内外遥感监测土壤水分的发展情况进行了回顾，简单总结了国内外常用的遥感监测土壤水分的方法及其原理，对目前遥感监测土壤水分领域的研究重点和未来发展方向进行了评述。以改进的热惯量法和植被缺水指数法等为主要代表的土壤水分遥感监测方法日臻成熟，可以投入业务运行；随着成本的不断降低，微波遥感是监测土壤水分的最有希望的方法之一。
This paper reviewed the development of soil moisture by remote sensing at home and abroad, briefly summarized the methods and principles of remote sensing monitoring of soil moisture at home and abroad, and reviewed the research focus and future development of soil moisture monitoring by remote sensing. With the improved method of thermal inertia and vegetation water shortage index as the main representative of the soil moisture remote sensing monitoring method is maturing, can put into business operation; as the cost continues to decline, microwave remote sensing is the most promising method of monitoring soil moisture one.
