Abstract: Based on the national groundwater monitoring project groundwater monitoring and provincial groundwater monitoring, abundant monitoring data of water level, water temperature and water quality have been obtained.The monitoring data are analyzed and studied, and the dynamic characteristics of groundwater level, water temperature and typical ions in major basin areas of Shaanxi Province are summarized.In recent years, the water level in the main basins of the province has been basically stable and slightly increased, and the water level in some areas has risen and fallen. The diving water level in the Guanzhong Basin has basically increased steadily and slightly, and the confined water level has generally increased significantly. The confined water level in some areas such as the built-up area of Xi'an has increased significantly, and the diving water level in the main basins of southern Shaanxi has basically stabilized and decreased slightly.The change of diving water level in the main basin area is greatly affected by rainfall, and the change of pressure water level is greatly affected by groundwater exploitation. The groundwater temperature in the main basin area is basically stable and slightly increased. The ion concentration of submersible groundwater in Guanzhong and Hanzhong basins is basically stable. The typical ion content of confined water in Guanzhong Basin is basically stable, and some ion content has gradually decreased in recent years.
