摘　　要：掌握低纬度沿海地区海潮、理论固体潮、观测井水位观测曲线的日变特征及表现形式,使用快速傅里叶变换分离各谐波,提取优势频率,分析海潮对海南地区观测井水位观测数据的影响,发现距海岸线较近的向荣村井受海潮影响较大,水位观测曲线与海潮均表现为单峰单谷的日变特征。It is introduced, the tide tidal theory and the characteristics of water level observation, in the coastal areas of low latitudes. Using fast Fourier transform spectral analysis on the data of the harmonic value and dominant frequencies. Influence of water level observation data from the tide has been analyzed in Hainan. It is found that the Xiangrong village well near the coastline is greatly affected by the sea tide The water level curve and the tide show the diurnal characteristics of single peak and single valley.
