Monitoring of vegetation degradation in typical grassland with grassland health index

Abstract

Abstract: We established a regression model between Grassland Health Index(GHI) and visible/infrared and applied GHI in TM.Compared with NDVI image on the TM data,GHI reflects effectively the human disturbance on grassland.Moreover,GHI image could illustrate vegetation pattern,especially patch structure,better than other indices.Applying GHI to the historical TM data of this region,the vegetation cover change and change mode of grazing were discussed.
