翻译草地资源是陆地上重要的生物群落类型之一。全球草地资源非常丰富总面积达671700hm2占世界陆地总面积的5217生物量占全球绿色植物的36~64。草地资源不仅为人类提供了大量的生物资源而且对维持整个陆地生态平衡、保护人类生存环境具有重要地位和作用这是其它自然资源所不能替代的。我国不同类型的草地总面积约为3928万hm2约占陆地总面积的近一半为现有农田面积的4倍左右。其中北方天然草原约占我国草地

Grassland resources are one of the important types of biotic communities on land. The global grassland resources are very rich, with a total area of 671,700 hectares, accounting for 52.17% of the total land area in the world, and the biomass accounts for 36% to 64% of the total green plants in the world. Grassland resources not only provide a large number of biological resources for humans, but also play an important role in maintaining the ecological balance of the entire land and protecting the human survival environment, which cannot be replaced by other natural resources. The total area of grasslands of different types in China is about 39,280 hectares, accounting for nearly half of the total land area and about four times the existing farmland area. Among them, the natural grasslands in the northern region account for about 78% of the grassland area in China and are the main body of grasslands in China. The grasslands in the semi-arid areas of the northern region not only provide an important production base for grassland animal husbandry in China, but also play an important role in wind and sand control, climate regulation, water conservation, environmental beautification, and air purification.
