The geological action and its evolution are important driving forces for the formation of regional ecological environment pattern. The surface geological constructions of lithosphere formed by geological action is the carrier of soil circle, water circle, atmosphere and biosphere. Geological construction restricts geological disasters and topography, hydrogeological conditions, soil physical and chemical properties, and thus plays an important role in the overall ecological balance. The ecological geology survey, which takes geological construction as the research unit, returns to the foundation, traces the origin, builds the bridge between ecological environment and geological conditions, and explores the mechanism of ecosystem operation and evolution from the perspective of geology. In the practice of ecological geological survey based on geological construction in the Daliangshan area, this paper explored a set of compilation methods of soil geological maps, ecological geological profile maps, and ecological geological maps, other ecological geology series maps based on the study of formations, which are suitable for southern mountainous areas. It is considered that the ecological geological series maps should be the reflection of the earths surface system with the integration of lithosphere, pedosphere and biosphere: one is to express the distribution and characteristics of the surface matrix layer (lithospheric surface and pedosphere) as the material basis of the ecological environment; the second is to express the current situation and distribution of the ecosystem and human activities covered by the surface; the third is to express the ecological function attributes of each ecological geological unit. The compilation of ecological geological series maps based on the study of geological formations can systematically reflect the current situation, characteristics, distribution and interaction of ecological geological elements in the earth surface system in the study area. It is an expansion 〖JP2〗of the service field of geological survey results, endows the existing geological survey results with new life, and provides a geoscience basis for ecological protection and restoration and land and space
