土壤退化与草地退化关系的研究

内蒙古草原在畜牧业生产及环境生态上均占有重要的地位 ,但草地退化比较严重 ,土壤是草地生态系统的基础环境 ,土壤退化与草地退化关系十分密切 ,都受到自然因素与生产活动的影响 ,但土壤退化比草地上植被的退化缓慢 ,土壤具有较强的抗拒退化的能力 ,它是土壤性质的综合表现 ,可以称之为土壤稳定性 ,土壤的稳定性是支撑草地生产稳定和恢复的重要因素 ,在评价与改良退化草地时 ,要充分了解土壤的退化程度 ,引起退化的主导因子 ,因地制宜地采取措施才能收到良好的效果

Relationships Between Soil Degradation and Rangeland Degradation

Mongolia grassland plays an important role in animal husbandry and in ecosystem and environment.Soil is a part of the ecosystem.The degradation of soil closely relates with the degradation of vegetation of grassland.They both are affected by nature factors and human activity.But soil degradation is slower than the degradation of grassland vegetation.The soil is stronger than the vegetation in resisting degradation,which depends on the soil nature of stability.The soil stability is an important factor that keeps the of grassland stability production and recovery of degraded grassland.In order to evaluate and use suitable measure to ameliorate the degraded grassland,we need to understand the degraded degree of the soil and the main factors causing the degradation.
