世界遗产—四川黄龙钙华景观研究进展与展望

Progress and Future Prospect in Research on the Travertine Landscape at Huanglong,Sichuan——A World's Heritage Site

本文在分析了有关四川黄龙钙华景观研究的主要文献的基础上,综述了目前对黄龙钙华景观形成(钙、水、CO2来源;钙华沉积速率等)及退化方面(砂化、变黑等)的研究进展,以及这些研究中存在的问题,提出了下一步急需开展的研究工作(如旅游带入的磷酸盐污染对藻类的生长以及水藻本身对钙华的侵蚀和沉积作用等),这些研究工作旨在为黄龙钙华景观的保护、修复和可持续利用提供科学依据。

This paper summarized the achievements in research on the formation （e. g. the source of calcium, water and carbon dioxide） and degradation （such as travertine weathering and darkening） of the travertine deposits in the Huanglong Ravine, made by scientists both at home and abroad. At the same time, the remaining unresolved problems in these research work were raised. Then, future research needs to resolve these problems （ such as the influence of phosphate pollution brought by tourist activities on the growth of aerial and aquatic algae in the Ravine, and travertine deposition）, aiming at providing the scientific basis for the landscape protection, restoration and sustainable use of the world＇s natural heritage site.
