摘要: 依据干旱区绿洲生态环境特点，建立了完整的生态脆弱性评价指标体系。结合GIS和遥感技术，分别从生态压力、生态敏感度和生态稳定度3方面对研究区生态脆弱性进行分析，并运用综合指数法、层次分析法得出综合评价结果。结果表明，研究区80%以上的区域已达到中度脆弱级别，近1/6的区域为重度脆弱区，在分布上呈现从东向西明显增加的特点。生态脆弱性表现出了显著的土地利用效应，随着脆弱度等级的增加，荒漠化面积所占比例大幅度提高。进行荒漠化治理、保证生态用水是吐鲁番绿洲生态建设的关键。

Abstract: The Turpan Oasis, located on arid and semi arid area in the east of Xinjiang, is affected by land degradation and desertification due to interaction of a set of natural and anthropogenic factors. It is a typical and key agricultural area with apparent oasis ecosystem vulnerability and sensitivity. Carrying out ecological environment vulnerability research in Turpan region has a great strategic meaning to eco environment restoration and eco environment long lasting development. In this study, the theory and method of ecological environment vulnerability were studied, and the concept of ecological environment vulnerability was put forward. From the characteristics and the causes of ecological vulnerability, we built multiobjective and multilayer ecological vulnerability evaluation index system framework, and a Pressure state respond (PSR) model was built to evaluate the ecosystem vulnerability. The results showed that: ① more than 80% of the total area has reached the moderate degree of ecological vulnerability, and nearly 1/6 of the total area is up to the serious level. ② There is a visible spatial distribution of the vulnerability degree in the whole study area, which is obviously increasing from the east to the west; meanwhile, the ecological vulnerability degree of inner oasis is significantly lower than the outward parts. ③ The results of the ecological vulnerability degree have a significant relationship with the land cover and land use, the vulnerability degree is increasing synchronous with the rise of the ratio of desertification land. ④ Desertification control and ecological water use guarantee are key points of the ecological restoration and reconstruction in the Turpan Oasis.
