摘　　要：分析福建省数字化水位、水温记录的日本9级地震的同震响应,发现:水位初始变化多为下降;水震波的最大双振幅随着水位日变化幅度的增大呈对数关系增大,还受到该井潮汐因子的影响;水温同震响应多表现为下降一上升恢复,水位异常幅度越大,水温的异常幅度越大,水温的异常持续时间越长。This paper analyzes the digital water level and temperature in Fujian Province which recor- ded coseismic response characteristics of magnitude 9.0 earthquake in Japan. The initial wa- ter level mostly goes down firstly. The maximum double amplitude of water waves reflects logarithmic increase not only with diurnal variation of water level, but also with the influence of the tidal factor. Most of the water temperature coseismic response shows down-up image in the Jiangdou well, Longtian well and Lianjiang well. The more abnormal water level is, the more abnomal water temperature. The abnormal of water temperature last longer time.
