摘要
总结了常用的遥感监测土壤水分的基本原理和方法,介绍了国内外在这一方面所取得的主要成果。以改进的热惯量法、作物缺水指数法和植被指数法等为主要代表的土壤水分遥感监测方法日臻成熟。G IS技术的广泛应用,土壤水分遥感监测模型的优化,以及微波遥感的应用将是该领域的重点研究方向,同时指出在土壤水分监测方面应走多学科综合的道路。
In this paper , the basic theories and methods of soil moisture monitoring by remote sensing are simply summarized, and then the national and international main progresses are reviewed. The results showed that the methods on soil moisture monitoring by remote sensing, which are mainly stood for by improved thermal inertia, CWSI and vegetation index, are becoming mature. The extensive application of GIS technology ,the optimization of the model of remote sensing monitoring of soil moisture and the application of microwave are the key direct of future study. Meanwhile, some views are pointed out and indicated that the soil moisture monitoring should carry out a new way which combine many subjects in the future.
