吕梁山林区退化草原生态修复措施与效果

Ecological Restoration Measures and Effects of Forest Degraded Grassland in Lvliang Mountain

党的十八大以来,国家高度重视生态文明建设,草原生态保护被提升到重要位置。本文以山西省吕梁山国有林管理局关上林场134 hm2草原退化修复实施情况为例,详细分析了草地退化成因,修复措施及效果。项目实施后吕梁山林区退化草原的植被综合盖度提高10~15%,鲜草产量提高8~19%,草地退化势头基本得到遏制,但居高不下的载畜量依然存在,修复后的草地依然有再次退化的可能。

Since the 18th National Congress of the Communist Party of China,the state has attached great importance to the construction of ecological civilization,and the ecological protection of grassland has been promoted to an important position.In this paper,the causes of grassland degradation,restoration measures and effects of grassland degradation were analyzed in detail,taking the implementation of 2000 mu grassland degradation restoration in Guanshang Forest Farm of National Forest Administration Bureau of Lvliang Mountain in Shanxi Province as an example.After the implementation of the project,the comprehensive vegetation coverage of the degraded grassland in the Lvliang Mountain area increased by 10-15%,the yield of fresh grass increased by 8-19%,and the trend of grassland degradation was basically contained,but the high livestock carrying capacity still existed,and the restored grassland still had the possibility of degradation again.
