Abstract: Ecological geology is an interdisciplinary subject to study the relationship between ecosystem and geological environment. which plays an important theoretical support role in the ecological protection and restoration of land and space. The ecogeology in China is still in the exploratory stage after years of development and sedi-mentierung. The authors in this paper summarize the relevant research progress of ecogeology at home and abroad, based on a large number of previous studies. Internationally, Russia has established an ecogeological survey and research system, and the United States has conducted the research on the earth’s critical zone, which is a theme very consistent with the ecogeological research. In China, ecogeological researches mainly focus on the process and mechanism of ecology-geology interaction and systematic ecological restoration under the influence of geological environment. On this basis, the authors in this study put forward the understanding of the meaning of ecogeology and the understanding and thinking of the research content, method and technology innovation of ecogeology and the construction of discipline system, which would provide reference for serving the overall protection of mountains, rivers, forests, farmlands, lakes, and grasslands, system restoration, comprehensive management and deepening research of ecogeological system.
