摘要:
相对于传统的农业干旱监测手段，遥感技术监测土壤水分的方法在农业干旱监测中有着不可替代的优势。基于裸露地表、部分覆盖度地表和全植被覆盖地表3种不同下垫面类型，评述了不同下垫面下农业干旱遥感监测方法的研究进展、适用范围和其优缺点，提出了未来农业干旱遥感监测的发展方向和应用前景，并对我国土壤水分遥感监测现状和发展前景进行了展望。
Compared with the traditional agricultural drought monitoring method, remote sensing monitoring soil moisture has irreplaceable advantages. Based on the bare ground, the part of the vegetation and the vegetation cover the surface, this paper reviewed the method, scope, advantages and disadvantages on different underlying surface of remote sensing monitoring on agriculture drought, introduced the future development direction and application of agricultural drought remote sensing monitoring, and analyzed the present situation and development prospect of remote sensing monitoring soil moisture in our country.
