摘　　要：数字遥测地震台网的测震能力图是衡量台网测震水平的一个重要标志,它既能反映一个台网的监测精度,更能反映一个台网的监测范围。要作出台网测震能力图,首先要获得台基振动数据,并对该数据作处理,然后根据相应的公式计算出起算函数R(△)、震中距△和台站监视半径r,最后作出测震能力图。The map of monitoring capability of digital telemetry seismic network is an important basis to evaluate monitoring Ievel of the network. It is not only reflecting the accuracy of a net work, but also reflecting the monitoring range of a network. If we want to draw a map of seismic observation of a network, firstly, we must acquire station ground micro tremor data and process them, then compute a calibration function of magnitude(R(△)), epicenter dis-tance(△) and observation radius of station. Finally work out a map of seismic observation.
