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．
