| 摘 要： | 2008年3月21日和2014年2月12日在新疆和田地区于田县先后发生两次MS7.3地震，两次地震震中相距110 km. 根据大震现场考察的结果，两次地震的宏观异常表现有较大差异．本文从发震构造、 震源深度和震源机制的角度，结合发震时间和空间分布等，分析了两次于田地震宏观异常异同点的可能原因, 初步总结了新疆地区地震宏观异常的空间分布特征、 物理特征和时间特征, 并结合哈萨克斯坦地震生物观测的研究现状，对我国现阶段的地震宏观观测给出一些建议性意见．

| Abstract: | There were two MS7.3 earthquakes occurred in Yutian, Xinjiang,Chinaon 21 March, 2008 and 12 February, 2014, respectively. Seismic geologi-cal surveys were carried out after both earthquakes. The surveying results show that the seismic macro-anomalies are quite different in behavior from each other, although the epicenters of the two earthquakes are only 110 km in distance. The present paper analyzed the possible reasons for macro-anomalies of the two Yutian earthquakes in behavior from the aspect of seismogenic faults, focal depth, focal mechanism and the spatio-temporal distribution of the earthquakes. The seismic characteristics in spatial distribution, physical behavior and temporal regularity in Xinjiang region are concluded. In addition, some instructive suggestions were mentioned out for macroscopic observation of earthquake inChina, combined with the progress of biological precursors of earthquakes attained inKazakhstan. |
