外文摘要：Ocean tide is the dynamic basis driving the hydrodynamic changes of groundwater. In order to explore the influence of ocean tide on the groundwater dynamics in Naozhou Island, Guangdong Province, the groundwater level and salinity were used as the main indicators, and the frequency characteristics of groundwater dynamics relative to tides were analyzed by power spectrum. Moreover, the amplitude and phase of groundwater dynamics were analyzed by combining wavelet transform and cross-correlation methods. The results show follows: (1) The response of groundwater to tidal loading has a certain spatial range. The horizontal influence of ocean tide on the groundwater level in Naozhou Island is about 400-500 m. (2) The distance from the sea and the aquifer properties are the main factors affecting the hydrodynamic response to the tide. (3) The channel connecting groundwater and seawater in Naozhou Island is distributed in the Quaternary medium sand layer. When the aquifer has a good hydrodynamic response to the tide and good connectivity with seawater, the seawater salt is more easily transmitted to the groundwater. The response analysis of groundwater dynamics to ocean tides can identify the influence range of ocean tides effectively, providing an important basis for the salinity phenomenon of groundwater in the island or nearshore areas. ? 2025 China University of Geosciences.
