摘要
高寒草地分布在高海拔、低热量生态环境；植物组成多系低温生态类型，群落外貌低矮；草地具有一定的生产力和经济价值，且利用方式和改良途径有较大的一致性。它是一类特指的天然草地泛称，也是一类可更新的再生资源和人类经营畜牧业的生产资料。组成天山高寒草地的植物约６００～７００ 种，具有一系列适应高寒生态环境的生态生物学特点，依其划分８ 个生态生物学类群和６ 个群落学类型。从三个方面进行了饲用评价，指出了存在问题。
The alpine grassland is distributed in high altitude and low heat environment.The eco-type of its plant composition mainly is low temperature type with dwarf community appearance.Grassland has certain productivity and economic value,and the ways of its utilization and improvement are somewhat coherent.This conception is a common form for natural grassland,and also is a kind of renewable resources and productive material of animal husbandry. The alpine grassland in Tianshan Mts.consists of 600-700 species,which has a series of eco-biological adaptation characteristics to high-cold environment.Based on these characteristics ,it can be divided into 8 eco-biology groups and 6 community types. At the present,the fodder value of grassland was evaluated,some existing problems were revialed,and some rational suggestions were advised from three aspects.
