【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。更多还原

【Abstract】 It showed unique form and distribution pattern in the growth of Qinghai grassland.Horizontal distribution was presented in north area being exclusive of Qilian Mountains.Natural grassland translated from temperate steppe to desert gradually,between the west of Huang River area lifting step by step,via the base of Qinghai lake-Gong He,and getting to Qaidam Basin.The succession occurred from meadow of Mountain forest,alpine irrigation meadow,Alpine meadow(Kobresia myosuroides),Alpine(Stipa capillata Linn) grassland in the general grass type.The distribution of natural grassland areas appeared to be discontinuous,and overlap between level and vertical distributions.更多还原
