摘　　要：青海天然草地在发育形成上表现出其特殊的类型和分布规律。在北半部(不包括祁连山地)表现为径向的水平分布规律。从湟水流域向西,地势逐步抬升,经青海湖盆地、共和盆地,到柴达木盆地,天然草地由温性草原逐渐向温性荒漠过渡。在青南高原面上由东南向西北,草地类型大体出现山地疏林草甸→高寒疏灌草甸→高寒(嵩草)草甸→高寒(针茅)草原的演替序列。且天然草地的水平地带分布呈不连续性,以及水平分布和垂直分布的叠加性。It showed unique form and distribution pattern in the growth of Qinghai grassland. Horizontal distri- bution was presented in north area being exclusive of Qilian Mountains. Natural perate steppe to desert gradually, between the west of Huang River area lifting Qinghai lake - Gong He, and getting to Qaidam Basin. The succession occurred est, alpine irrigation meadow, Alpine meadow （Kobresia myosuroides）, Alpine grassland translated from tem- step by step, via the base of from meadow of Mountain for- （ Stipa capillata Linn） grass- land in the general grass type. The distribution of natural grassland areas appeared to be discontinuous, and overlap between level and vertical distributions.
