ON THE RELATIVE STAGES OF TOPOGRAPHY DEVELOPMENT

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.
