“十五”数字化网络项目完成后，我国地震井水位观测网已颇具规模。为了摸清其监测现状，为未来台网优化改造、仪器更新提供依据，开展了观测网的清理和监测效能评估。评估结果显示，总体上，观测网中有61． 8% 的水位观测站监测效能良好。有73． 5% 的观测站的观测环境符合地震井水位观测要求;观测网的运维状态总体趋好，有75% 的观测仪器的运行率在95% 以上;大部分的水位观测站监测地壳应力变化、地震活动的能力较强。但仍然有些观测站，因观测井先天不足、环境干扰、仪器老化、运维水平低等问题，亟待通过观测环境改造、仪器更新、运维管理培训等措施来提高监测效能。大约有6． 5% 的观测站因观测环境不合格需要停测。

In order to understand monitoring efficiency status of well-water-level observation network in China after the completion of the digital seismic network project for the tenth“Fire-year Plan”，and to Provide a basis for the future network optimization and equipment updating，wellwater- level observation network was evaluated． On the whole，61. 8% observing stations with good monitoring effectiveness． Observation environment of 73. 5% observing stations meets the monitoring requirements of well-water-level． The operation state of the observation network is getting better，operation rates of 75% observing instruments are upwards of 95% ． Most well water levels can monitor crustal stress changes and seismic activities． But，there are some observation stations with well its problem，environmental disturbance，instrument aging，and operation and maintenance of low level，which need to improve monitoring efficiency level by taking the observation environment improvement， equipment update， management training and other measures． About 6． 5% of the observation stations for observational environment unqualified needs to stop stop observing stop observing observingobserving．
