塔里木沙漠公路防护林横穿塔克拉玛干沙漠,利用3-30 g·L-1地下咸水灌溉,风沙、高温、盐分等多种胁迫因子影响人工生态系统的持续和稳定．通过对多种胁迫下人工防护林的结构特征(包括生产力、更新能力、生物多样性等)和功能特征(生物地化循环,如:防护林土壤生理生化特性、地下水)的变化研究,探讨防护林与环境之间的相互关系．在此基础上,将决策分析引入塔里木沙漠公路防护林稳定性研究,筛选出影响防护林系统稳定性的障碍因子,建立沙漠公路防护林稳定性的综合指标体系,评价防护林稳定性,并将生态稳定性概念应用于生态系统管理．研究表明:现阶段防护林塔里木沙漠公路防护林系统处于相对脆弱状态,气候条件是系统稳定的主要干扰因素,但能够通过人工措施改善沙漠公路防护林系统的环境质量,增加了系统的稳定性．
The Tarim Desert Highway Shelterbelt crosses the Taklamakan Desert and affects the sustainability and stability of artificial ecosystems by using three to 30 g · L-1 saline water irrigation, wind-blown sand, high temperature and salt stress factors. Through the research on the structural characteristics of artificial shelterbelts (including productivity, renewal ability, biodiversity, etc.) and the changes of functional characteristics (such as biochemical cycle, such as the physiological and biochemical characteristics of shelterbelts, groundwater) The relationship between. Based on this, the policy analysis is introduced into the stability research of Tarim Desert Highway Shelterbelt, the factors that affect the stability of Shelterbelt are screened, the comprehensive index system of desert shelterbelt stability is established, the stability of shelterbelt is evaluated, and the concept of ecological stability Applied to ecosystem management. The research shows that the Tarim Desert Highway Shelterbelt system is in a relatively fragile state at present stage, and the climatic conditions are the main disturbing factors of the system stability. However, the environmental quality of Shelterbelt system of Desert Highway can be improved by manual measures and the stability of the system is increased.
