该文在回顾遥感监测土壤水分研究进展的基础上,对当前使用较多的旱情监测方法,如热惯量法、植被供水指数法、距平植被指数法、作物蒸散及微波监测等方法的应用范围进行了比较分析,并对我国土壤水分遥感监测现状、发展前景、业务化能力等发展趋势进行了分析和展望,认为数据处理能力、算法精度和结果验证以及旱情评价体系的建立是我国当前旱情监测中急需解决的问题。
On the basis of reviewing the progress of research on soil moisture monitoring by remote sensing, this paper analyzes the current application of drought monitoring methods such as thermal inertia method, vegetation water supply index method, anomaly vegetation index method, crop evapotranspiration and microwave monitoring methods And analyzed the development trend of soil moisture remote sensing monitoring in China, such as the status quo, development prospects and operational capabilities of soil moisture monitoring in China. It is concluded that the data processing capability, algorithm accuracy and result verification as well as the establishment of drought evaluation system are the current monitoring methods of drought monitoring Urgent need to solve the problem.
