Based on the qualitative description of the driving factors for grassland degradation in the mixed cropland-grassland region in Northern Shaanxi Province

we chose the dominant factors that were closely correlated to the grassland degeneration and also relatively easy to acquire

and obtained the most dominant factors affecting the grassland degradation using a principal component analysis and multiple linear regression analysis.Furthermore

for those selected factors

we proposed the prevention measures to control the degeneration of grassland in Northern Shaanxi Province.In addition

we suggested some concrete counter measures based on the moisture conditions and the severity of grassland degradation.Finally

we proposed a model of reconstructing the degradated ecosystem in Northern Shaanxi Province.
