| 摘 要： | 以青海省境内广泛分布的温性草原类草地为研究对象,初步探讨了该类草地区域分布规律及植被结构特点。认为温性草原类是青海省天然草地垂直带谱的基带草地,其分布范围东西跨越5个经度带,南北约跨越1个纬度带。分布地区海拔高度一般在1700~3500m,但在柴达木盆地及青南高原区海拔可上升至3900~4400m。草地植被组成每平方米牧草种类约为10~17种,以旱生丛生禾草西北针茅、疏花针茅、长芒草、芨芨草、青海固沙草等为优势种。由于受人类活动影响较强,在利用上要做到保护和利用、建设和发展并举,实现可持续发展。

| Abstract: | This paper preliminary investigated the spatial distribution pattern and community structure of the province wide distributed temperate, grassland. The conclusions drew from this study is ： Its east - west band is across five longitudes and north tribution of vegetation types in - south distribution This type steppe is the base - band grassland of vertical disnatural grassland. The distribution area is in commonly 1700 - 1700m altitude, but in the Chaidam basin and the southern of Qinghai plateau can rise to 3900 - 3900m above sea level. The vegetationcomposition of every square metre pasture species approximately 10 to 17 ,The dominant species of Qinghai temperate grassland mainly were Stipa krylovii, S. bungeana, S. penicillata. Achnatherum splendes, and Orinus kokonorica. Due to the effect of human activity is stronger, On the use to simultaneously protection and utilization, the construction and development, To achieve sustainable development. |
