四川康定县玉农希钙华景观及其水循环系统

The Yulongxi travertine landscape in west Gongga Mountain of Kangding County may be regarded as another subnival belt karst landscape with the worldwide heritage potential value following Jiuzhaigou and Huanglong. The survey is the second batch of projects for important geological heritage protection feasibility planning in Sichuan arranged by Bureau of Land and Resources of Sichuan Province. The authors investigated for the first time the Yulongxi travertine landscape and studied geological heritage landscape characteristics and hydrological cycle systems. On such a basis, a regional comparative analysis was made, and the formation mechanism and evolutionary regularity of the landscape were tentatively discussed. The Yulongxi travertine landscape has con-siderable scientific, aesthetic and visual values and can compare well with Jiuzhaigou and Huanglong. It is hence very necessary to protect this landscape with scientific and rational measures.
