中文摘要：
土壤水分是衡量土地退化和干旱的重要指标，是气候、水文、生态、农业等领域中的重要参数，遥感技术已经成为监测土壤水分与旱情的重要手段。本文在分析和总结了前人研究成果的基础上，综述了遥感技术监测土壤水分的主要技术手段和方法，从可见光和近红外遥感、热红外遥感、微波遥感和高光谱遥感四方面总结了遥感技术监测干旱区土壤水分的内容和现状，指出了这些方法在干旱区研究存在的不足，最后对未来的趋势进行了展望。
英文摘要：
Soil moisture is an important parameter factor in fields of hydrology, meteorology, soil science, ecology and agricultural scientific research, remote sensing monitoring soil moisture technology has become an important means. This paper summarized the technical measures and methods to study soil moisture monitoring with the remote sensing technology, and made a review on the soil moisture condition monitoring, methods about visible and the near infrared remote sensing, thermal infrared remote sensing technology, microwave remote sensing and hyperspectral remote sensing technology, and pointed out shortages of the remote sensing methods. Finally, the future possible prospect of the developing trend on soil moisture monitoring by remote sensing was reviewed.
