| Abstract: | Drought is one of nataual disasters intimidating agricultural development in the world.Remote Sensing has become the important technique monitoring soil moisture and drought.The advantages and methods of monitoring soil moisture and drought by MODIS data were analysed and summarized.The monitoring themes which were usually used,such as direct measuring way,Temperature Vegetation drought index(TVDI) space way,vegetation water monitoring way,water wane index etc.were introduced in detail.Finally,the future development trends in the field was also prospected. |
