典型旅游城市环境脆弱度评价与分析——以昆明市主城区为例

Evaluating and Analyzing the Environment Frangibility of Typical Tourist City——Take Kunming Urban Area for Example

昆明市作为旅游城市,自然、人文旅游资源丰富多样,但由于主城区受特殊的地质地貌、水文条件等自然因素和人文因素的影响,使昆明市成为典型的环境脆弱区.通过分析昆明市具体情况,结合Delph i法,确定了适合该区的环境脆弱性评价的关键指标.在此基础上,利用AHP法确定评价指标体系,借助综合指数法对昆明市主城区2007年的生态环境做了定性和定量的评价.结果显示,昆明市主城区2007年的生态环境为中度脆弱.最后,探讨了昆明市主城区环境脆弱性的成因,并提出一些建议.

Kunming, as a tourist city possesses of a variety of natural and cultural tourism resources, due to its special geological landforms, hydrological conditions and other natural and human factors is becoming a typical environmentally fragile city. By analyzing the specific circumstances of Kunming and combining with experts＇ advice, we find out the index system to evaluate the environment frangibility of Kunming. By means of AHP and the method of multi-indexes a qualitative and quantitative evaluation are made on the environment of Kunming in the year of 2007. The results indicate that the environment of the Kunming urban area is moderately fragile. Finally, the causes leading to the environmental frangibility are explored and suggestions are proposed.
