基于AHP—模糊综合评判的旅游开发生态风险评价研究——以甘肃河西走廊为例

Study of Ecological Risk Assessment of Tourism Development Based on AHP-fuzzy Comprehensive Evaluation——Taking Hexi Corridor Area in Gansu Province as an Example

以甘肃河西走廊为研究对象,对其旅游开发生态风险源和风险终点进行识别。运用AHP法和专家咨询法构建了包括14个指标变量的生态风险评价指标体系,计算得出各风险指标的权重;利用模糊综合评判法,对河西走廊旅游开发生态风险进行综合评价。结果表明:河西走廊旅游开发生态风险最终评价得分属"较高风险"区间,指标层中的固体污染、植被覆盖率下降、土地不合理利用、土地沙漠化等风险比其他风险更高,是更加需要防范的生态问题。

This paper took Hexi Corridor of Gansu Province as the research object,and identified the ecological risk sources and risk end points of its tourism development,and constructed an ecological risk evaluation index system including 14 index variables by using the AHP and the expert consultation method,and calculated the index weight of each risk.The fuzzy comprehensive evaluation method was used in this paper to comprehensively evaluate the ecological risk of tourism development in the Hexi Corridor.The results showed that the final score of the ecological risk assessment of tourism development which belonged to the'higher risk'level.The risk of solid pollution,vegetation coverage decrease,land irrational use,as well as land desertification was higher than other risks,and the related ecological problems needed to be paid more precaution.
