论地貌发育的相关阶段

ON THE RELATIVE STAGES OF TOPOGRAPHY DEVELOPMENT

本文认为,各种地貌形态均是由古今各种内、外动力长期相互作用所形成的不同类型地貌叠加构成的。以第四纪时期300万年以来的地貌发育过程来看,表现出若干因素相互关联的相关阶段的相互更替。其中最具有代表性的,如具有活动性与相对稳定性相互交替的新构造运动的阶段性,和一般以干冷气候条件为特点的冰期与一般以湿热气候条件为特点的间冰期气候相互交替的第四纪气候变化的阶段性。就是和地貌发育的相关阶段最相关联的,它们二者是构成地貌发育的相关阶段的主要因素,形成不同类型地貌互相叠加。

Topography is erally composed of various overlapping landforms resulting from diffirent geological processes, ancient and present, endogenic and exogenic. In Quternary of 300 million years, there are some factors of relative stages influencing topography development. For example,active and stable periods of neotectonic movement change in succession; interglacial and glacial stages substitute each other, the former is warm and moist,the latter is cold and dry. Neotectonic movement and climate change are close relative to the stages of topography development and key factors bring about dfffirent types of overlapping landforms.
