河西走廊灌丛植被的生态学研究

本文从生态学基本原理出发 ,对河西走廊灌丛植被以群落建群种为基础进行了分类研究 ,将灌丛植被划分为 8个类型 ,分别对灌丛群落的分布、生物学特性、生态学意义以及各类灌丛植被与土壤之间的关系 ,特别是对灌丛植被在改善河西走廊生态环境的作用、在干旱荒漠系统的防风固沙、建立荒漠草场以及防治荒漠化等方面进行了研究 ,并就河西走廊荒漠系统生态重建与可持续发展提出了对策

Ecology of Shrub Vegetation in the Hexi Corridor.

On the basis of the basic principles of ecology,the shrub vegetation in the Hexi Corridor was classified into eight types,of which distribution,ecological characters,ecological significance and relations with soil were studied,with emphasis on their roles in improving the eco environment of the Hexi Corridor,in breaking winds,fixing sands,establishing desert grasslands and controlling desertification in the arid desert system.On such a basis constructive strategies are put forward for rebuilding ecology in desert system and sustainable development of the Hexi Corridor.
