【摘要】 根据华北地区东南部的地震活动、地质构造和地球物理等资料，对介休－新乡－溧阳北西向地震带的地震地质条件作了分析。此地震带具有统一的现代区域构造应力背景，是华北东南部的一条现代地壳剪切破裂带；沿此带发育由一系列晚第三纪以来继承性活动的和新产生的北西向断裂组成的活动断裂带，它斜穿不同的构造单元是一条新生地震构造带更多还原

【Abstract】 On the basis of the data of seismicity, geological structures and geophsics, we have done an analysis on the seismogeological chracteristics of the Jiexiu Xinxiang Liyang northwest trending seismic zone located in the southeast area of North China. This seismic zone is a recent crust shear rupture zone under the uniform modern tectonic stress field in a large scale; and along it there are a series of newly generating northwest trending faults which continued or began to develop since the Neogene period. They make up an active fault zone which extends through different tectonic units. Therefore, it is a newly formed seismic zone.更多还原
