| 摘 要： | 在以山地高原为主、缺乏大平原的云南省,人口、耕地.经济、文化活动的中心主要分布和集中在“坝子”中,“坝子”是云南经济发展的基础,其在国民经济发展中的地位远较其他地貌类型重要. “坝子”常被等同于“山间中小盆地”,但在现实中,“坝子”已远远超出了“山间中小盆地”的范畴,包括成因各异的多种小地貌类型,是对云南省一类较为特殊的小地貌的统称.云南“坝子”一般由地球内力作用形成雏形,再经各种外营力改造而成,其中流水作用和人为地质作用最为重要.因成因不同,“坝子”的形态及特征各异,据此可划分出构造坝、水成坝、冰成坝、火山坝四大成因类型.

| Abstract: | As Yunnan, a border province at southwestern part in China, takes mountainland and plateau as its main dominant feature, and lacks grand plain, inevitably, the center of population, arable land, economy, and cultural activities principally contributes or focuses on Bazi （a word in Yunna dialect for flatland） , As a result, Bazi or flatland in Yunna serves as the base for the development of economy, and plays as the leading part in the de- velopment of national economy better than other kinds of landform and terrain. Unfortunately, Bazi or flatland is often regarded as a piece of land equivalent to a small piece of basin-land among mountanous valleys. However, inreality, Bazi or flatland shows people features far beyond a small piece of basin-land among mountanous valleys, as it consists of not only various microtopographies formed from different causes, but is also a general name for a special kind of microtopographies in Yunnan. Generally, flatland or Bazi in Yunnan gets its embryonic form by the internal force of the earth, and gets into its shape under various exogennetic forces. Among these forces, the force of drainage and human-made geological forces are the most workable factors. Since causes of flatland are so different from each other, the patterns and features vary one the other greatly. Hence, an effecitve division of pattern and feature of flatland in Yunnan into tectonic, draining, ice-forced, and volcanic flatland will be of great practical ValUe. |
