摘要: 通过建立西藏生态环境稳定性评价指标体系和利用AHP 法确定评价因子权重,构建西藏生态环境稳定性综合评价模型,采用栅格GIS 的叠加分析功能生成评价结果图,根据结果对西藏生态环境稳定性的空间分布特点做出分析,并提出相应对策。研究表明,西藏生态环境稳定性的总体状况良好,稳定性差的区域主要分布在雅鲁藏布江中下游地区,约占全区面积的9.78%,因此,对该地区要加大生态环境建设力度,防止生态环境的进一步退化。

Abstract: By making a evaluation index system and using AHP to determine the evaluation factor's weights, this paper builds the valuation model of eco-environmental stability of Tibet and uses the overlay function of raster-GIS to make a result map, and finds the distribution characteristics of eco-environmental stability of Tibet based on the analysis of result map. The study shows that the eco-environmental stability of Tibet is almost good and the unstable area that is only 9.78% of the total area of Tibet is distributed in the middle and low reaches of the Yarlung Zangbo river. To protect the eco-environmental of the unstable area from farther degenerating, the government should pay more attention on the eco-environmental construction work on this area.
