摘要: 以长江源区生态地质环境调查基础数据为契机,采用层次分析法(AHP)模型的方式,提出长江源区生态地质环境指标体系,最终划定本区域生态地质环境质量综合指数。在定性的基础上从一个崭新的角度定量化分析长江源头生态地质环境质量的变化,得出影响本区域生态环境的主要因素为动植物环境的改变,进而揭示长江源区生态地质环境发展的未来趋势,为今后研究长江源区生态地质环境质量及其合理发展做出了较为客观、准确的评价。Abstract: Using the opportunity of basic eco-geological environment survey data from the source region of Yangtze River,we propose an index system of eco-geological environment for this region by adopting the analytic hierarchy process(AHP)model and finally delineates the regional eco-geo-environmental quality indexes.These make a quantitative analysis of eco-geological environmental changes of this source region area from a brand new point on the qualita tive basis,indicating that the main factor affecting the ecological environment in this area is the change in environment of animals and plants,further more,this fact reveals the future development trend of the eco-geological environment of this area,resulting in a more objective and more accurate evaluation about environmental quality and rational development of the region.
