新疆高寒草原植被类型及分布特征

Vegetation Types and Distribution Characteristics of Alpine Steppe in Xinjiang

高寒草原是指在海拔较高、气候环境寒冷且干燥的情况下生长成的一种植被形态,在草原种类中是最能耐寒的一类,是草原群落的一个独特的植被类型。在新疆面积较大,分布广,类型多样。从昆仑山、阿尔金山、帕米尔高原到天山、阿尔泰山均有分布。对于保持水土、涵养水源以及畜牧业生产和草原生态保护建设都具有十分重要的地位。本文根据新疆高寒草原的植物生长特点对主要植被类型进行了划分,并对其分布特征进行了描述,这对新疆植物资源的合理开发利用、保护和增值具有十分重要的指导意义。

The alpine steppe refers to the grassland where the terrain is steep and the climate is dry and cold. The alpine grassland is the most hardy in all grassland types, and is a unique type of vegetation in grassland community. The alpine steppe is distributed in xinjiang from Kunlun mountain, Aljinshan, Pamir plateau to Tianshan and. It has large area, wide distribution and diverse types. It has a very prominent position in the maintenance of water and soil, water conservation, animal husbandry production and grassland ecological protection. In this paper, based on xinjiang plant growth characteristics of main vegetation types of alpine grassland has carried on the classification, and its distribution features are described, for the rational development and utilization of plant resources in xinjiang, protection and appreciation has important guiding significance.
