摘　　要：土壤湿度在全球水循环运动中扮演着非常重要的角色,是水文、气象和农业研究中的重要参数,国内外都极为重视对土壤湿度的研究。国外利用可见光、红外、热红外、微波遥感监测土壤水分已有三、四十年的历史,随着研究的深入和技术的发展,现已形成地面、航空、航天、多星的立体干旱遥感监测格局。国内遥感监测土壤湿度的方法主要有微波遥感、热红外遥感、距平植被指数法、植被供水指数、作物缺水指数等方法。本文通过对国内外已有的土壤湿度遥感监测方法的介绍和总结,对比分析了各种方法的原理、适用领域及其研究进展,并针对新疆的具体情况,认为借助Mod is影像进行新疆地区土壤湿度的监测是较为可行的一种方法。The soil humidity plays a very important role in global water circulation motion, it is a key parameter in hydrology, weather and agriculture researches, and it has attracts many attentions national and international. Soil humidity monitoring with visible light, infrared, thernlal infrared, microwave remote sensing has nearly 40 years history at abroad. With the development of technology, a stereoscopic dry remote sensing monitoring pattern of the ground, aviation, aerospace, many stars has been established. The methods of remote sensing monitoring soil humidity mainly include the microwave remote sensing, thermal infrared remote sensing, even vegetation index method, vegetation supply water index method and crop shortage water index method. Based on the introduction of existed methods, the principle, concrete suitable field as well as the progress in the research have been described and compared in this paper. In addition, aimed at the specific situation of Xinjiang, it concludes that soil moisture monitoring by Modis image is an available method.
