摘要:在气候变化背景下，青海三江源地区游憩功能格局发生改变。综合运用PC （Pairwise Comparison）法、AHP （Analytic Hierarchy Process）、指标模型、相关分析等方法，构建三江源地区游憩功能评价框架，研究1978-2012年三江源地区3类游憩功能格局的演变，以及这种演变与气候变化之间的关联。研究表明：（1）气候条件、独特景观、植被条件、地表覆被与地形条件等要素影响着三江源地区游憩功能的形成，不同要素在美感、参与机会与适宜环境3类游憩功能形成过程中发挥的作用不同，且具有非线性贡献；（2）三江源地区的美感功能较强，其次是参与机会功能，而适宜环境功能较弱；（3）气候变化在不同程度上改变了三江源地区的3类游憩功能，其中，适宜环境功能的响应最强烈，主要表现为提升；参与机会功能的响应程度最弱。该研究完善了游憩功能的理论与应用，并为气候变化背景下三江源地区旅游可持续发展决策提供参考。



Abstract:In the context of climate change, the pattern of recreational functions in the Sanjiangyuan region has changed. This paper comprehensively uses the PC (Pairwise Comparison) method, AHP (Analytic Hierarchy Process) method, index model, correlation analysis, and other methods to construct a framework for evaluating recreational functions. On this basis, the change of the three types of recreational function patterns in the Sanjiangyuan region from 1978 to 2012 was traced, and the relationship between this evolution and climate change was examined. Results shows that: (1) factors such as climatic conditions, unique landscapes, vegetation conditions, surface cover, and terrain conditions affect the formation of the recreational function in the Sanjiangyuan region. The different factors play different roles in the procedure of such formation, and these factors have nonlinear contributions. (2) The aesthetic function of the Sanjiangyuan region is stronger, followed by the participation function, and the suitable environment function is the weakest. (3) Climate change has changed the three types of recreational functions in the Sanjiangyuan region to various degrees. Among them, the response of the suitable environment function is the strongest which has been improved, while the response of the participation function is the weakest. The study expands the theory and application of recreational functions, and can help tourism decision-makers of the Sanjiangyuan region towards a sustainable development under climate change.
