| Abstract: | The crop water stress index(CWSI) model was a combination of remote sensing image, graph and meteorological data. This paper studied the method and feasibility of monitroing drought based on CWSI on a large area, using land information system(LIS) as tool. The experimental resulted in Huanghuaihai(HHH) showed that the LIS United remote sensing image. Map grasph and ground station meteorological data. So monitroing accurately and speedily drought in HHH plain was realized basically. |
