The earth's surface is the survival home for human beings, and especially the surface patterns can directly or indirectly affect human life, production, and social and economic activities. Both geomorphology and ecology are closely related to human beings. Natural and human entities are both attached to the earth's surface. Therefore, the subject is collectively called ecological geomorphology. No subject is more closely related to human beings than ecological geomorphology. It directly influences human survival location, survival guarantee, production direction, industrial layout, transportation, urban and rural construction, and so on. Therefore, the study of ecological geomorphology is a basic and applied subject, which is to ensure the sustainable and coordinated development of human survival and social economy, and to realize the strategy of ecological civilization. Ecological geomorphology is a subject that studies the relationship between ecology and geomorphology. The subject system includes geomorphological basic disciplines, ecological basic disciplines and ecological geomorphological disciplines formed by their interaction. The subject also contains ecological geomorphological regionalization, ecological geomorphological typology, ecological geomorphological resources, ecological geomorphological petrology, remote sensing and GIS technology for ecological geomorphology, and ecological geomorphological management and planning, which is still being explored. The ecological and geomorphological structure can be expressed as follows: geomorphologic and biological composition, types, regional combination, quantitative composition and its spatial arrangement and combination. Based on the theory of ecological and geomorphological structure, this paper systematically summarizes its function. To sum up, the eco-geomorphological structure includes regional structure, type structure, resource structure and rock state structure. Different sructural types have different functions, including improvement of the quality of China's physiographical regionalization and spatial positioning, ecological assessment and ecological design, land use assessment and utilization structure adjustment, geological and geomorphological disaster causes and disaster prevention and reduction countermeasures. In order to achieve the coordination between function and sustainable benefits, the authors have made a whole set of function, formed a functional system, and put forward a design path to improve functional capability from the perspective of regulation and management.
