Abstract：
The typical drought event occurred from April to November 2001 in North China Region. In order to calculate the drought degree and its impacts on vegetation, the SPEI (Standard Precipitation Evapotranspiration Index); LAI (Leaf Area Index) anomalies and FAPAR (Fraction of Absorbed Photosynthetically Active Radiation) anomalies were used for the Drought Degree and Its Impacts on Vegetation Dataset development. The dataset includes: (1) the border file of the North China; (2) the drought severity index based on SPEI from April to November in 2001 in the region; (3) the monthly drought degree data from April to November in 2001 in the region; (4) the LAI anomalies from April to November in 2001 in the region and the accumulations of LAI anomalies during this periods; (5) the FAPAR anomalies from April to November in 2001 in the region and the accumulations of FAPAR anomalies during this periods. The data results show that: the area where LAI anomalies and FAPAR anomalies are less than 0 is also the area experienced severe drought. And compared with the croplands, the LAI and FAPAR anomalies of grasslands are much smaller; reasonably, the response of different vegetation to the drought is also different. The dataset is achieved in .tif and .shp fomats. The spatial resolution is 0.01° and the compressed data size is 34.5MB.
