Keywords:   GPS, GIS, Grassland resource

GPS and GIS technologies were used to investigate the grassland resource, and grass yield, terrain and soil parameters were gained. The spatial different of grass yield and soil parameters were identified in this paper. The gray relationships between grass yield and terrain and soil parameters were analyzed. The results showed that the parameters order of impact grass yield was determined by the gray relationship coefficients.
