摘要
对于近年来国内外遥感监测土壤水分的理论、方法的发展和应用进行了全面的回顾,重点介绍了目前已经比较成熟和广泛应用的基于可见光与热红外波段的特征空间方法和微波遥感方法。并对各种遥感监测土壤水分方法的优缺点作出评价,提出了遥感监测土壤水分方法存在的不足,指出了今后发展的方向,并展望了遥感监测土壤水分的发展前景。
A general review of recent development and application of the technology of remote-sensing in monitoring soil moisture was done with emphasis on introducing the relatively mature and extensively used feature space method and microwave remote-sensing method based on visible light and thermal infrared bands. It also analyzed advantages and disadvantages of various remote-sensing methods in monitoring soil moisture, pointed out shortages with the remote-sensing methods, predicted directions of future development and foretold prospects of the technology of using remote-sensing to monitor soil moisture monitoring.
