摘　　要：以峨眉山风景区旅游生态系统为对象,运用能值理论和分析方法对其进行研究,构建了旅游生态系统能值分析模型和指标体系。并对系统内自然、社区、经济三个亚系统进行分析,评价峨眉山旅游生态系统系统可持续发展能力。研究表明:(1)2017年峨眉山风景区旅游生态系统能值总量为6.60×10^20 sej,其中可更新资源投入为6.68×10^19 sej,社区居民生活投入为3.16×10^19 sej,投入为4.95×10^20 sej,旅游投入占能值总使用量的75.00%。(2)峨眉山旅游生态系统能值可持续发展指数较低,系统资源负载率较高,为消费性经济,对系统外部资源投入需求较高,较为依赖外界大量的不可更新资源投入。峨眉山风景区旅游生态系统整体可持续发展能力处于中等水平。In this paper,the tourism system of Emei Mountain Scenic Area is studied by using emergy theory and analysis methods,and the emergy analysis model and index system of tourism system are constructed.The three subsystems about nature,community and economy in the tourism system of Emei Mountain Scenic Area are analyzed to evaluate the sustainable development ability of the tourism system of Emei Mountain.The results show that:(1)In 2017,the overall emergy value of the tourism system of Emei Mountain Scenic Area is 6.60×10^20 sej,of which renewable resources input is 6.68×10^19 sej.Community residents’life input is 3.16×10^19 sej.And emergy input is 4.95×10^20 sej.Tourism input accounts for 75.00% of the overall emergy usage.(2)The tourism system of Emei Mountain Scenic Area has a low emergy sustainable development index and a high load rate of system resources.It is a consumptive economy.It has a high demand for external resources input and relies on a large amount of non-renewable resources input from the outside world.The overall sustainable development ability of the tourism system of Emei Mountain Scenic Area maintains at a medium level.
