摘　　要：估算台网监测能力的方法有多种,本文采用目前最常用的根据近震震级公式,通过确定振幅比,用量规函数反推单台控制距离的方法,依据4台以上定位原则,确定各台控制距离相交部分为数字遥测地震台网给定震级下限的监测范围,并绘制出赣南数字遥测地震台网的监测能力图,为江西省地震速报范围及速报震级的确定提供了理论依据。There are many ways to evaluate the earthquake-monitoring capability of digital seismological network. This paper uses the usual method based on the near earthquake magnitude formula to get the amplitude ratio and then inversely applies the calibration function to determine the distance controlled by a single station. Based on the location principle by four stations, the common part of the four circles, each of them determined by a single station, is called as the monitoring area of the digital seismological network at given lower limit of magnitude. In this paper we have drawn the monitoring capability map of South Jiangxi Seismological Network that can give the theoretical basis to get the range and the magnitude of earthquake rapid determination.
