Abstract:
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.
