Landform type classification and coding rules
1 Scope
This document proposes the classification principles of land and submarine landform types, and stipulates the classification system and landform types of land and submarine landforms.
Coding and naming schemes.
This document is applicable to information extraction, comprehensive classification, thematic mapping, data integration and database construction, and statistical analysis of land and seabed landforms.
application.
2 Normative references
This document has no normative references.
3 Terms and definitions
The following terms and definitions apply to this document.
3.1
Endogenic force
The power generated by the earth's internal thermal energy, chemical energy, gravitational energy and the earth's rotation energy.
3.2
Exogenic force
The power that acts on the earth's surface through solar radiation energy, gravitational energy, and the gravitational energy of the sun and the moon through the atmosphere, water, and organisms.
3.3
Main force
The main internal or external forces that shape the landform.
3.4
Landform
The various forms of the earth's surface (including the seabed) are formed by the interaction of internal and external forces.
3.5
geomorphological age
The relative geological period in which the landform was formed or the absolute number of years from now.
3.6
Geomorphic units are characterized by their geometrical features, surface contours created by internal forces, and intensity characteristics shaped by external forces.
It is composed of morphology, combined morphology, micro-morphology and slope morphology.
3.7
Geomorphological type
Based on the similarities and differences in landform genesis and morphology, it is divided into several different types, including genesis type, morphological type,
The morphogenetic combination type composition.
