Application of Background Information Database in Drought Monitoring of Guangxi in 2010

摘要：

In this paper, use Nanning city as an example to show application of Background information database in drought monitoring. A near-real time drought monitoring approach is developed using Terra-Moderate Resolution Imaging Spectoradiometer (MODIS) Normalized Difference Vegetation Index (NDVI) and Land Surface Temperature (LST) products. The approach is called Vegetation Temperature Condition Index (VTCI), which integrates land surface reflectance and thermal properties. VTCI is defined as the ratio of LST differ-ences among pixels with a specific NDVI value in a sufficiently large study area; The groundmeasured precipitation data from a study area covering Nan-ning in Guangxi, CHINA, are used to validate the drought monitoring ap-proach. Taking the result of drought monitoring in background information of Nanning city ,the area of farmland drought of Mild drought Moderate droughts Severe drought were 223607.2 Ha ,310596.9 Ha and 513.2 Ha.
