| Abstract: | he evapotranspiration of the wheat fields is estimated by meteorological satellite's thermal infrared data in combination with measuring data on ground surface and conventional meteorological data.On the basis of water balance equation,the water requirement of the wheat and the drought index,drought monitoring is achieved through the consideration of variation of soils water content in the wheat fields and drought distribution. |
