我国气候地貌的基本特征与分区初探

本文简述了我国气候地貌的三个基本特征:1.我国自从第四纪初期以来,即分化出现代三个大的气候地貌区;2.气候地貌类型复杂多样;3.早第三纪我国盛行热带气候,因而造成热带地貌的遗迹在我国广泛存在的现象.我国三大气候地貌区,其界线与三大自然地理区吻合,其中东部季风湿润地貌区可再分为四个气候地貌地区(带).

A Preliminary Study on the Basic Characteristics of Morphoclimate and Its Regionalization in China

This paper deals with three basic characteristics of morphoclirnate in China: (1) Three major morphoclimatic regiems can be divided clearly in the Quarternary period; (2) There are various types of morphoclimate, such as glacial, periglacial, arid, semiarid, tropical, and especially subtropical monsoon; (3) During Early Tertiary period the development of landform was governed by climates resembling those of today' s seasonally tropical and subtropical areas, which created the wide etchplain in China.Three major morphociimatic regions are demarcated: (1) Eastern Monsoon China, (2) Northwest Arid China, (3)The Qinghai-Tibetan Arid-Frigid Plateau.East China may be divided into four morphociimatic zones: (1) N Northeast China in the permafrost region, (2) North China, Northeast China temperate zone with very cold winters, (3 ) Central China, subtropical zone with cool winters, (4 ) South China, humid tropical zone.
