中文摘要	西气东输管道工程对沿线生态系统形成干扰,导致土壤质量下降,植被退化,生物多样性降低,风沙危害加剧等环境灾害,影响区域的生态安全,威胁到输气管道的安全运行.稳定性不同的生态系统对管道工程干扰有的反应不同,评价工程沿线生态系统的稳定性,有利于合理制定施工规范和开展工程后的生态恢复,对于保障区域生态系统和管道的双重安全具有重要意义.从生态系统受干扰后恢复能力的角度,在地理信息系统(GIS)平台支持下,采用图层权重-级别打分叠加模型,对管道沿线生态系统做稳定性评价.把生态系统稳定性按稳定性从低到高依次分为不稳定、欠稳定、稍稳定和稳定四个等级,结果发现沿线区域面积占15%的生态系统不稳定,52%区域欠稳定.针对稳定性低的盐土荒漠地区,沙质荒漠地区和棕漠土灌木荒漠三类地区,设计有利于促进生态系统恢复的友好环境构建对策.
英文摘要	The West-East Gas Pipeline Project (WEPP)starts from Lunnan Town of Luntai County Xinjiang, and then crosses arid desert region from west to east part of China, The project disturb the ecosystems along the pipeline, and lead to many environmental calamities such as, soil quality decline, vegetation degradation, biodi-versity decline and so on. It also imperils regional eco-safety and the safety of the pipeline. The ecosystems in different stable levels perform different responsibilities to the disturbance. Ecosystem stability assessment will be in favor of designing proper measures to promote the ecosystem resilience and help to protect the safety of pipeline. This paper focuses on ecosystems resilience, and values the ecosystems stability by Weight-degree mod-el with the help of GIS, The stability is classified into four levels, namely, unstable, under stable, sub-stable and stable. Soil and vegetation are selected as the assessment factors. Stability levels are calculated out based on the evaluations that are given by experts according the resilience ability. It is found that Saline desert and sandy desert both belong to unstable ecosystems; meadow and shrub desert belong to under stable ecosystems, these kinds of ecosystems occupy 53% of research region area; oasis are sub-stable; and stone deserts are stable. In order to promote ecosystems restoration in lho.se unstable areas, such as salinized soil area, sandy soil area and brown desert soil area, corresponding rehabilitation measures are de-signed. In saline desert area, it is important to create favorable condition for vegetation restoration and sail shells recovering al ground surface. The dug ottt soil should be stacked and filled back respectively according lo primary soil layers order. Further more, man-made ridge due to pipeline can be use to collect runoff, which will promote surface vegetation recovering. For sandy desert area, it is necessary to protect the roots of plants. Grass lattice technology should be used to fix sands. Moreover, some human activities, such as grazing, that will destroy vegetation along the pipeline should be forbidden. In shrub desert area, the key point is to protect gravel layers at the ground surface. Gravel layers destroyed should be paved artificially, in order to conserve the soil. Man-made ridge due to pipeline can also be use to collect runoff, which will promote surface vegetation recovering.
