青藏高原东缘九寨沟高寒钙华分类与命名

九寨沟钙华景观不仅有着独特的旅游与美学价值，在古气候、古灾害、古地震/活动构造、高原隆升以及人类世等研究中也能提供重要的地质档案。无论从旅游与科普的角度，还是从科学研究出发，开展钙华分类研究必然是前提、也是基础。基于地球系统科学理论，从物质来源到沉积环境，分析了无机和有机对钙华沉积的控制因素，按照相（分为亚相、微相）、类（分为大类、亚类）的沉积特征对钙华进行了分类，划分依据是:沉积环境决定了水动力条件与生物参与度，进而形成了千变万化的钙华沉积形态，最终架构了丰富多彩的钙华景观。所划分的结构—成因类型对“九寨沟式钙华”的科学研究有重要指导意义；从旅游与科普角度开展的钙华地貌—形态分类，可为大众旅游、科普以及管理部门提供更高的辨识度及生态保育参考。 

Classification of Alpine-type travertine in Jiuzhaigou valley on the eastern margin of the Qinghai-Tibet Plateau

The travertine in Jiuzhaigou valley not only has unique tourism and aesthetic values，but also plays an important role in geological archives for the study of paleo-climate，paleo-hazards，paleo-earthquake/active structures，plateau uplift and the Anthropocene. Whether from the perspective of tourism，science popularization，or scientific research，classification research on tufa is the premise and foundation. In this article，based on the theory of earth system science，we analyze the controlling factors of inorganic and organic from the source of travertine material to the depositional environment，and classify it according to facies，classes and subclasses of sedimentary morphology. The criterion for the classification is that the depositional environment determines the hydrodynamic conditions and the degree of biological participation，which in turn forms the ever-changing tufa deposition geomorphology， and finally constitutes a colorful travertine landscape. The structure-genesis types of tufa divided herein have important guiding significance for the genetic research of "Jiuzhaigou-type travertine". Meanwhile，this article also makes a landscape-morphological classification of tufa from the perspective of tourism and science popularization，which provides a higher degree of identification and ecological conservation data for mass tourism，science popularization and management departments.
