关於中国地理区域的划分,事实上有种种困难:(1)精密的地质,地形,气候,土壤,天然植物,及人口分布之研究尚未普遍於全国各地,综合的地理研究殊难着手。(2)地理的要素既不止一端,难免顾此失彼。(3)地理区域之范围必须大小适宜,(艹盍)太大则失於笼统空泛,太小则失於零碎淆乱,然何地应合称一自然区域,何地应分作数个单位,实无简单一定之标准。

The major division of China is into two regions with marked contrasts in their geographical environment: the Eastern Monsoon Regions and the Central Asiatic Plateaus, the physiographic boundary of which follows approximately the Kbingan Mountains, the In Shan, the Szech-wanese Alps and the edge of Yunnan Plateau.
