摘　　要：提出了孤立中强地震的潜在震源区划分及其参数确定的思路和方法，即在综合考虑孤立中强地震所在地震区（带）的总体地震构造特征与地震活动水平的基础上，利用历史地震等震线、余震分布、区域应力场及震源机制解等资料，确定其潜在震源区的参数。另外，还对孤立中强地震的潜在震源区的可靠性作了初步分析。In this paper,the approaches are developed to delineate the potential seismic sources of moderately strong earthquakes that do not have clear seismogenic tectonical settings.That is,on the basis of comprehensive analysis on the general characteristics of seismogenic background and seismicity in the related seismic zone(belt),data such as isoseismals,spatial distribution of after shocks,regional tectonic stress field and focal mechanisms are employed to the delineation of the potential seismic sources.Finally,the reliabilty of such potential seismic sources has been discussed.
