INTRODUCTION TO GEOMORPHOLOGIC MAP OF CHINA SEA AND ADJACENT REGIONS(1:8 600 000)AND GEOMORPHOLOGIC LASSIFICATION BASED ON PLATE TECTONICS

本文论述了新近出版的１：８６０万《中国海区及邻域地貌图》采用的板块构造地貌分类的总体思路及分类方案。

Scientists have developed tectonic geomorphologic classifications in different ways based on plate tectonic theory.This paper deals with the ideas and methods of the geomorphological classification based on plate tectonic thory in the Geomorphologic Map of China Sea and Adjacent Region(1:8600000).This classification has three characteristics:1.Plate tectonic theory was used In the first order classification,and the divisions of continental landforms and submarine landforms were not accepted as units of the first order classification.2.According to the modern plate environments,intraplate and plate margin geomorphologies were classified.The modern and the plaeo-plate margins were not considered as geomorphological types in the same order.3.The horizontal movement was emphasized and the intraplate organic classification was used for dividing mountain types.The 12 first-order global geomorphologic types were divided.The studing areas has three first order units:the intraplate continental landform,the continental margin trench-arc-basin and the oceanic-margin trench-arc-basin landforms.They were further divided into 11 second-order types and more than 20 third-order types.
