摘要
重庆市武隆县芙蓉洞是世界自然遗产,但随着旅游经济的快速发展,芙蓉洞的洞穴景观发生退化,影响了旅游业的可持续发展。本研究分析了温度、湿度、CO2浓度及洞穴通风等主要环境因子变化特征和规律,研究了洞穴景观退化机理,并提出其保护对策。游人和洞穴灯光释放的能量导致芙蓉洞内气温升高。由于洞内外的温度差和空气流通,洞穴内表现出“夏季高温、冬季干燥”的特征。洞穴CO2浓度会随游人进入的数量增加而明显升高。洞穴升温、灯光热量释放,及空气对流导致洞穴湿度降低,使景观产生干裂和风化等现象。气流带入的洞外气体及高浓度CO2溶解于水汽,溶蚀洞穴景观。洞穴灯光为苔藓类植物生长提供了条件,附着于洞穴景观的表面;以及洞穴大气粉尘的进入,致使洞穴景观暗沉发黑。洞穴内部环境保护能有效防止洞穴景观退化,保证游客健康旅游,实现旅游资源的可持续开发利用。Furong Cave in Wulong County of Chongqing is a world natural heritage, but with the rapid development of the tourism economy, the cave landscape of Furong Cave has been degraded, which has affected the sustainable development of tourism. In this study, the characteristics and rules of major environmental factors such as temperature, humidity, CO2 concentration and cave ventilation were analyzed, the mechanism of cave landscape degradation was studied, and the protection measures were proposed. The energy released by visitors and cave lights causes the temperature inside Furong Cave to rise. Due to the temperature difference and air circulation inside and outside the cave, the cave shows the characteristics of “high temperature in summer and dry in winter”. The CO2 concentration of the cave will increase significantly with the increase in the number of visitors entering the cave. The warming of the cave, the release of heat from lighting, and air convection lead to a decrease in humidity wi
