摘　　要：通过对银川盆地1970年以来中小有感地震活动特征的研究,认识到有感地震的优势分布空间、时间和震级范围。再研究中小有感地震地质构造背景和震源深度,分析银川盆地的沉积地层厚度,来解释中小地震震感强烈的原因。其结果可对有感地震突发后民众和政府采取正确应对措提供依据。This article research the characteristics of seismic activity in Yinchuan basin since 1970, me results show that felt earthquake advantages of distributed space, time and magnitude range. Further research and a felt earthquake geological background and focal depth, analysis of Yinchuan basin sedimentary strata thickness, to explain the small earthquake was felt strongly the reason. The result is a felt earthquake burst after the people and the government to adopt a correct answer measure provide a basis.
