Abstract

With Inner Mongolia as the study area, the authors selected the height, coverage and biomass as the single

indices for the assessment of grassland degradation based on field survey and random samples, and calculated the

grassland degradation index (GDI) by integrating the height, coverage, and biomass. According to a correlation

analysis between GDI and every vegetation index computed, the GDI and the MSAVI were chosen as the best variables to

build the grassland degradation model with linear regression by using of RS, GIS, and GPS techniques. The grassland

degradation time-space distribution and the variation tendency in 2002 and 2006 were also analyzed. It is concluded

that the vegetation degeneration situation has on the whole shown an improvement, but with partial worsening in 2006

compared with things in 2002.
