摘　　要：在收集和整理上海及邻近地区1904年至今所有资料的基础上,确定了不同仪器的放大倍数与有效监测距离的关系,从而给出了这一地区分7个时间段的地震监测能力分布图。根据1987年上海台网的观测能力,导出了估算震中定位误差的统计模型,计算了它的定位精度,结果显示网内的震中位置水平误差大约为2km。Earthquakes,occurred in Shanghai and the adjacent area from 1904 to 1987,have been collected and sorted out in this paper.The relationship between seismometry gain and monitoring range have been used to determine the distribution of the monitoring abili- ty in seven interva ls.According to the monitoring ability of Shanghai Telemetered Seis- mic Network in 1987,we calculated its location accuracy with statistical model,the result shows that the horizontal errors of the epicenter is about two kilometers.
