我国农业干旱遥感监测的现状与展望

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。

PRESENT STATUS AND PROSPECT OF REMOTE SENSING SUPERVISION AND TEST FOR ARID AGRICULTURE IN CHINA

On the basis of reviewing the research progress on inspecting soil moisture by remote sensing,this paper compares the application scopes of many commonly used drought ravage testing methods,such as heat inertia method,vegetation water supply index method,vegetation index method,crop vaporization and micro-wave testing method,etc.It also analyzes the present status,development prospect and operation ability etc.development tendency of soil moisture remote sensing and inspection in China.The paper deems that the most urgent issue for solving the problems in present drought ravage inspection and test are data processing ability,arithmetic accuracy,result validation and establishment of a system for evaluating drought ravage.
