| 摘 要： | 西北干旱、半干旱荒漠区是我国典型的荒漠生态系统.灌木是荒漠植被的主要组分,它在维持荒漠生态系统生物多样性、生态服务功能及其稳定性方面具有重要作用.20世纪下半叶,人口和经济快速增长导致的高强度人类活动,深刻地改变了荒漠生态系统的结构及水分和能量循环过程,致使灌木植物严重退化.为了保育灌木资源,提高人们对灌木在草地恢复中重要作用的认识,从改良土壤、物种多样性、防风固沙等方面论述了灌木在草地恢复过程中的特殊作用.建议在草业方面开展深入研究,以便使灌木在草地恢复中发挥更大的效能.

| Abstract: | Arid and semi-arid desert region in northwest is the typical desert ecosystem in China,and plays a vital role in maintaining bio-diversity eco-service function and stability of desert ecosystem.During the second half of the 20 th century,with the rapid development of population and economy,human activities changed structure and process of water and energy cycle in desert ecosystem,which caused severe shrub deterioration.In order to conserve shrub resources and enhance the recognition of the importance of shrub grassland restoration process,the paper dissertated its special effects on soil improvement,plant diversity,wind breaking and sand fixation.It was suggested that shrub be studied further to exert its greater efficiency in grassland restoration. |
