摘要
通过对青海天然草地牧草混合草群营养成分分析,总结了青海天然草地的几个营养类型。结果表明,青海天然草地主要营养类型为氮碳型草地面积最大,其次是氮碳—灰分型草地。两营养类型草地面积为3902.60×104hm2,占全省天然草地总面积的93.10%。从而构成了青海天然草地的主体。
By analyzing the nutrient of natural grassland, the nutritional types of natural grassland were classi- fied. The analysis results also indicate that the nitro- carbon grassland is the majority type, the next is nitro- carbon - ash grassland, the acreage of these two types is 3902.60 ×10^4hm2, comprising of 93.10% of entire natural grassland in Qinghai.
