To serve the construction of ecological civilization and the management of natural resources, also to promote the coordination of mountains, rivers, forests, fields, lakes, grass and sand life community, China Geological Survey has organized the national hydrogeology and water resources survey at the catchment scale, and focused on the operation and maintenance of the National Groundwater Monitoring Project, the national annual simultaneous measurement of groundwater level, the national groundwater resources evaluation, the study of water balance in key areas, the construction of hydrogeology and water resources intelligent service system, and serving for the poverty alleviation and rural revitalization. Numerous achievements have been made in various aspects since 2019. First, the Overall Design of Geological Survey for Water Resources Management that was based on the concept of ecological priority, which covers atmospheric water, surface water, groundwater and marine water has been complied to lead the transformation and development of geological survey. Second, the National Groundwater Monitoring Project has been in efficient operation, and the monitoring data that being shared also have supported the groundwater management and study in the fields of natural resources, water conservancy, ecological environment and scientific research. Third, a complete national groundwater level unified measurement network with 56000 unified measurement points has been established to access annual change of groundwater flow field accurately. Fourth, a national annual groundwater investigation, monitoring and evaluation mechanism have been established and the evaluation results of the groundwater resource, the groundwater storage and its annual changes are obtained. Fifth, water balance research in key areas including Haihe River Basin has been carried out to understand the regional water balance, water resources evolution under the influence of human activities and its mutual feedback mechanism. Sixth, a national hydrogeology and water resources intelligent service platform has been constructed, a multi-element national hydrogeology and water resources database is initially established, and a groundwater resources online evaluation system has been developed. Seventh, the task of water seeking for poverty alleviation was completed with high quality, which provided strong support and services for poverty alleviation and rural revitalization.
