| 摘 要： | 岷山地区冰缘岩溶是处于岷山雪线下部冰缘环境的碳酸盐岩之溶蚀与冻融相互渗合、叠加的岩溶地质类型，具有碳酸盐岩溶场和冰缘岩屑与冰期、间冰期堆积物岩溶场的二元结构。岷山地区大多数碳酸盐岩处于较低的海拔区，在第四纪气温振荡回暖的影响下冰缘岩溶已经衰退，仅残留着早期冰缘岩溶形成的地貌和钙华体，现在的黄龙沟冰缘岩溶因其碳酸盐岩海拔高，仍处在第四纪末期冰川退缩后的冰缘环境，冰缘岩溶地貌和钙华体还在发育，不过现今全球性气温升高和人类的活动对冰缘岩溶都将产生负面影响，以钙华体为核心景观的黄龙、九寨沟风景区的管理部门应予加强监测和保护。

| Abstract: | Periglacial karst in the Minshan Mountains is characterized by binary texture of carbonate karst field and periglacial and glacial-interglacial karst field. The carbonate rock in the Minshan Mountains is characterized by low elevation which results in development of periglacial karst landform and travertine bodies in the Jiuzhai Valley-Huanglong Scenic Spots under condition of the Quaternary warm climate. Due to global warming people should strength monitoring and protection of environment in the Jiuzhai Valley-Huanglong Scenic Spots. |
