中文摘要	由于自然条件的边缘性和过渡性，吉林省西部生态系统脆弱性和敏感性显著，其土地利用呈现农牧业交错的过渡特征，是全球和我国土地利用／覆被变化（LUCC）研究的典型区和首选区。基于GIS技术的空间分析功能，建立了基本评价因素的数字环境模型。应用主成分综合分析方法，提出了生态脆弱态势指数模型，获取了吉林省西部近15年生存环境脆弱性变化的空间分布规律，以期为区域生态环境的治理与建设提供依据
英文摘要	The west Jilon Province is located in the transition zone from semi humid climate to semi arid climate with many types of ecological landscapes and is a typical area between agriculture and husbandry.Since the 1980’s,the land use/cover in this are have undergone dramatic changes.Under the pressure of population growth and excessive land exploitation,such as over grazing and over reclamation,the ecological environments that have been fragile become more vulnerable and unstable.On the basis of systematical analysis in the natural and artificial factors and their relations influencing environment evolution,the leading factors of eco-envrionment degradation are extracted qualitatively in this area.Under the GIS technology,digital environmental model is established.Using 100m*100m real area as basic unit,the spatial principal components analysis method is applied to calculate the eco-environment synthesis exponet according to the weight of some indexes.The eco-environment vulnerability index(EVI)is produced to evaluate the eco-environment fragile status during 1986-2000.Results show that the eco-environment quality gradally declines from the central t peripheral.The fragile status of some areas in the south sand land region,the central alluvial plain region and the north floodplain region has been exacerbated remarkably in recent 15 years.
