ON THE PRINCIPLE, CONTENTS AND METHODS USED TO COMPILE THE CHINESE GEOMORPHOLOGICAL MAPS TAKING THE 1:4 000 000 CHINESE GEOMORPHOLOGICAL MAP AS AN EXAMPLE
1993, 48 (2):
In order to work out a new generation national geomorphological map conforming to the modern geomorphologic theory and the mapping principles and to apply them to the researches and teachings related to national geo-sciences a nd environmental administration, under the sup-port of the related geomorphologic organizations of IGU and in cooperation with nine institu-tions in this country, the autors have succeeded in completing the Geomorphologic Map of China and the Neighbouring Areas (1:4, 000, 000), which will be published formally at home and abroad in 1993. This complete geomorphologic map takes the landforms within the national territory and the neighbouring areas as a single entity and gives expressions specifically to the basic laws of exogenic and endogenic geomorphic geneses and the mophology and its development processes on the basis of morpho tectonic. In morphotectonic classification, we use for the first time the viewpoint of mobility, with the plate tectonic theory as its centre. Based on the new classification concept of "Plate Margins and Intraplates", the continental landforms are divi-ded into two great geomorphologic systems: the plate margin and the intraplate. Their seven sub-systems and nineteen major types are also divided. The submarine landforms are divi- ded into three subsystems and ten major types. In relief form classification, the relief is di-vided into five amplitude classes and seven basic types by using of the new state-built and the computer-aid analyses and by the mapping of the nationwide basis relief form factors. In terms of exogenic landforms. in addition in the traditional Genetic-form types, one attached map de-pitting the ancient and present morphoclimatic zonal differentiations since the Cenozoic Era has been compiled. This map provides the basis nessary for the analysis of the mutual relation- ships between endogenic and exogenic agents.
