乡村旅游地生态系统安全评估研究——以岷江上游干温河谷区为例

Evaluation on Ecosystem Security of Rural Tourism Destination——A Case of Arid and Warm Valley in Upper Min River Basin

以岷江上游干温河谷乡村旅游生态系统为研究对象,根据"压力-状态-响应"模型原理,运用构建的乡村旅游生态系统安全评估体系,在确定系统不安全指数和评价指标权重的基础上,评价乡村旅游生态系统的不安全度。研究表明,在羌族乡村旅游发展过程中,生态系统质量、生物物种质量、森林覆盖率等指标成为岷江上游干温河谷系统安全的重要限制因素,而生态建设能力和环境保护意识成为生态安全响应能力的主要限制因素。研究不仅为岷江干温河谷生态环境的人文治理途径提供借鉴,也将为震后羌族区域经济恢复与持续发展提供决策指导。

Taking the arid and warm valley in upper Min River Basin as research object, this paper constructed an ecological security evaluative system of rural tourism based on Pressure - State - Response model. After defining the insecurity index and e- valuation indices of the target ecosystem, it evaluated the insecurity degree of rural tourism. The results show that ecological sys- tem quality, life species quality and forest coverage are the most important limiting factors of ecosystem security. Ecological con- struetion ability and environmental protection eonsciousness play major limiting roles for ecological security response ability in the arid and warm valley in upper Min River Basin. This study is not only beneficial to the management for the target region, but also provides reference for decision -making in rapid recovery after Wenehuan Earthquake.
