摘　　要：利用西安数字地震遥测台网记录的宽频带数字地震资料 ,测定了陕西地区环境剪应力值τ0 的分布 ,结果显示陕西地区存在着环境剪应力值τ0 的高值区。In this paper, using the broad band digital data recorded by Xi'an telemetry seismic network,the distribution of ambient stress τ 0 is determined.The results show that there exist several areas with high abnormal ambient shear stress τ 0 in Shaanxi Province.The relationship between these areas with geological structures and seismic activity is then discussed.
