摘要
通过对那曲地区主要牧区不同退化程度草地土壤的理化性质的测定，采用灰色系统的关联度理论和相关分析方法，分析了坡度、草地盖度、产草量与土壤退化的关系，以及土壤退化的原因。
By analysis on the physical and chemical properties of degraded grassland, adopting the analytical methods of grey relation and correlation analysis in main meadow of Naqu area, the relationship between soil degradation and slope gradient, grass cover degree, and grass yield was studied, the soil degradation reason was further discussed.
