Currently, sustainable tourism is becoming more and more important in developing ecological economies. To achieve low-carbon development, some industries, such as logistics and municipal solid waste, have already taken action, but tourism has not attached sufficient importance to this issue. This paper designs an ecotourism system including tourism, carbon waste (solid waste and sewage), and ecology (water supply and green areas) to simulate low-carbon ecotourism through a quantitative approach. This paper explores the tourism system as well as some interactive factors and studies their quantitative relationship based on historical data. A feedback-loop dynamical system model is designed to simulate tourism, waste carbon, and ecology simultaneously. Finally, a case study applying the feedback-loop dynamical system model to Leshan City, a typical travel destination with colorful natural resources in western China, is conducted to indicate the development of ecotourism in an environmentally friendly economy, which verifies the positive effects of the model. Results show a coordinating upward tendency of tourism, solid waste carbon, and ecology from the dynamical model. When tourism increases, solid waste accumulation increases; however, the amount of sewage dumped directly into nature decreases sharply. After analysis of investment policy scenarios, the research indicates that more funds for sewage treatment will attract more tourists. To maintain the equilibrium of carbon waste, more funds shall be invested in solid waste treatment in the long term. Some discussions about local policy are included.
目前，可持续旅游在发展生态经济中变得越来越重要。为了实现低碳发展，一些行业，如物流和城市固体废物，已经采取了行动，但旅游业并没有对此问题给予足够的重视。本文设计了一个包括旅游、碳废物（固体废物和污水）和生态（供水和绿地）的生态旅游系统，通过定量方法模拟低碳生态旅游。本文探讨了旅游系统以及一些交互因素，并基于历史数据研究了它们的定量关系。设计了一个反馈环动力系统模型来同时模拟旅游、碳废物和生态。最后，通过将反馈环动力系统模型应用于中国西部拥有丰富多彩自然资源的典型旅游目的地乐山进行案例研究，展示了在环保经济中生态旅游的发展，验证了模型的积极效果。结果表明，从动力模型来看，旅游、固体废物碳和生态呈协调上升趋势。随着旅游业的增长，固体废物的积累增加；然而，直接排入自然的污水排放量急剧下降。通过对投资政策情景的分析，研究表明，增加污水处理资金将吸引更多的游客。为了保持碳废物的平衡，从长期来看，应投入更多资金用于固体废物处理。文中还包括了一些关于地方政策的讨论。
