岩溶系统是地球表层系统的重要组成部分,其对环境的敏感性和自身的脆弱性值得关注与研究。世界自然遗产-黄龙的岩溶资源主要有钙华景观资源、水资源和生物资源。本文在对黄龙生物资源(钙华藻类)的调查研究中发现,藻类不仅会影响钙华景观的颜色,而且在钙华景观的形成中起到重要的生物岩溶作用。岩溶水资源为黄龙钙华景观的形成提供物质来源,岩溶水补给不足影响了钙华的发育,同时加剧藻类对钙华的侵蚀作用,严重破坏黄龙钙华景观的观赏性,导致整个岩溶系统失衡。另外,在调查中发现旅游活动引起的人为破坏及污染也对黄龙岩溶系统产生影响。在对黄龙景观、水和生物的研究基础上,提出了几点保护建议。本文希望可以对黄龙岩溶资源的了解与保护提供科学基础。
Karst system is an important part of the Earth’s surface system, its sensitivity to the environment and its own vulnerability deserve attention and research. World Natural Heritage - Huanglong karst resources are travertine landscape resources, water resources and biological resources. In this study, we found that algae not only affect the color of travertine landscape, but also play important biological karstification in the formation of travertine landscape. Karst water resources provide the material source for the formation of the Huanglong Travertine landscape. The shortage of karst water affects the development of travertine and aggravates the erosion of algae to travertine, which seriously damages the ornamental of Huanglong travertine landscape and causes the imbalance of the whole karst system . In addition, it was found during the investigation that man-made damage and pollution caused by tourism activities also had an impact on the Huanglong karst system. Based on the study of Huanglong landscape, water and biology, several suggestions for protection are put forward. This paper hopes to provide a scientific basis for the understanding and protection of Huanglong karst resources.
