MENG Xiao, LI Jing, REN Zhi-yuan, et al. Ecosystem Reconstruction Model of Degraded Grasslands in Mixed Cropland一Grassland Zone in Northern Shaanxi Province[J]. Bulletin of Soiland Water Conservation, 2011, 30(3): 140-144.DOI:
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.
