NDVI 1. On the basis of Normalized Difference Vegetation Index (NDVI) data with resolution of 1 km of NOAA/AVHRR in 1993 and NDVI data for MODIS in 2000 and 2006,the authors analyzed the NDVI spatial dynamic variations by changing intensive parameters in the source regions of the three river...
Variation in vegetation cover in Inner Mongolia has been previously studied by the remote sensing data spanning only one decade. However, spatial and temporal variations in vegetation cover based on the newly released GIMMS NDVI3g data spanning nearly thirty years have yet to be analyzed. In this...
