摘要
该图以多层次表示法和表列式分解型图例,着重表现构造地貌为基础的内外力地貌成因、形态及其发展过程的基本规律。在内力方面,采用板块构造理论为指导,表现了构造地貌;外力方面,除表现传统的堆积成因形态类型外,辅以气候地貌的地带分异;而形态分类则利用DTM,对国土地形进行了基本形态要素的机助分析与制图,并引进地形起伏度概念,调整了传统的形态分类方案。通过项目研制,作者力求探讨一种符合现代地貌学理论,服务于科研、教学和国土整治的新型国家地貌图。
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 abioad 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-picting 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.
Moreover, in this map the tabulated legend of the analytical types follows the method of 'indirect combination between the low-level types and the high-level units', so as to make the mapframe and the legend area be in a ratio of 10 to 1.48, which is the most concise among the maps in the same category so far in the world.
