【摘要】 考虑到既能使冰缘作用及形态类型地带性规律充分展示,又能反映出它们彼此之间的地域分异,对高亚洲冰缘作用类型区进行二级划分。首先,按气候条件分为3大类型区;其次,按构造运动性质、岩性不同,以及由此而引起的冰缘作用和形态垂直带诺结构特征的地域差异,将Ⅰ、Ⅱ类型区各划分为相应的3个亚类型区。更多还原

【Abstract】 Two hierarchic grades were introduced to classify the High-Asia Periglacial type zones in order to indicate not only the zonal characteristics of periglacial processes and their morphologic types, but also their regional differences. Firstly, three type zones were classified based on climatic conditions; secondly, based on the geological structure, petrologic composition, regional differences of periglacial processes and altitudinal morphologic characters caused by geological conditions, three sub-type zones were introduced in the first two great zones respectively.更多还原
