Further improve the service ability of regional comprehensive geological survey techniques and methods,and provide solutions and schemes for rural sustainable revitalization.Methods:By literature review method，model-building method，case analysis method and inductive method to propose focus of regional comprehensive geological surveys in rural sustainable revitalization.Results:Based on the geological perspective,rural Revitalization mainly includes the foundation of rural human and land security,industrial revitalization (including water supply security,agricultural geology,tourism geology,etc.),cultural revitalization of geological culture promotion,ecological revitalization (including geological heritage and environmental protection),personnel revitalization (including rural geological personnel training),organization revitalization (environmental governance organization improvement).The key contents of regional comprehensive geological survey such as geological disaster survey,engineering geological evaluation,hydrogeological survey,agricultural geological survey,tourism geological heritage survey are proposed to help rural revitalization.In order to improve the efficiency of assistance,it is necessary to do a good job in the top-level design of the project,formulating technical standards for regional geological survey in rural areas,constructing the working mechanism of serving the local government and carrying out systematic personnel training.Conclusions:Regional comprehensive geological survey is the basic work and important technical support for rural revitalization.In the future,the problems should be solved such as regional overall planning and implementation of key development villages and towns according to local conditions,the spatial scale matching between comprehensive geological survey and rural planning and construction,combined use of comprehensive geological survey and longitudinal professional survey,the overall utilization of engineering geological evaluation and rural underground space,and the connection between geological culture village construction and rural planning and construction.
