摘要: 草地退化是长时间多方面原因形成的，生态修复治理是解决草地退化的正确方法。通过山西草地生态类型的分布、特点，山西省天然草地等级评定的分析，可知山西草地退化程度以及治理的效果。通过对山西退化草地的原因分析，从退化草地生态修复理论、方法、保障措施等方面对退化草地生态修复治理进行阐述、探讨。为山西退化草地生态修复治理提供方法，为山西缓解草地退化实现良性循环提供了科学理论依据、政策性支持和阶段性目标。Abstract: Grassland degradation is formed by multiple factors over a long period of time. Ecological restoration and management are the correct methods to solve grassland degradation. Based on the distribution and characteristics of grassland ecosystem types in Shanxi, as well as the analysis of grassland grades, it can be known that the degree of grassland degradation in Shanxi is moderate, with a small proportion of excellent grassland and severe degradation, and a large proportion of moderate degradation. This is related to the natural factors such as the range and soil, climate conditions, and main vegetation of the grassland in Shanxi, as well as human factors such as excessive grazing, rampant mining and excavation by industrial and mining enterprises, regional economic development, and other factors. It is also related to policies such as the emphasis and investment on grassland in Shanxi. Through the discussion of ecological restoration and management methods for degraded grassland and safeguard measures for ecological restoration and management in Shanxi, this paper provides a reference for ecological restoration and management of degraded grassland in Shanxi, and proposes policy support and phased goals for the benign circulation of grassland in Shanxi.
