摘要:
在华北构造区划分出银川——河套地震带、汾渭地震带、河北平原地震带、东秦岭——大别地震带、郯庐地震带和长江下游——黄海地震带等6个地震带，并依据地震带构造特征和地震活动的差异性，将其中汾渭地震带划分为延庆——代县段、原平——襄汾段和侯马——渭河段；河北平原地震带划分为三河——涞水段、唐山——邢台段和安阳——成武段；郯庐地震带划分为开原——辽东湾段、渤海段、潍坊——嘉山段和嘉山——广济段；银川——河套地震带初步划分为银川段和河套段．同时，对河北平原地震带南界及其与东秦岭——大别地震带的关系，地震带不同区段存在的主震型和多震型特点，以及可能发生强震的危险区段进行了初步探讨．
Abstract:
In this paper, the North China tectonic region is divided into 6 seismic belts,i.e., Yinchuan-Hetao seismic belt, Fengwei belt, Hebei plain belt, East Qingling-Dabie belt, Tanlu belt and Downstream of Yangzi river-Yellow Sea seismic belt. Based on the difference in tectonic characteristics and seismic activity, the Fengwei seismic belt could be subdivided into Yanqing-Daixian segment, Yuanping-Xiangfen segment and Houma-Weihe segment; Hebei plain seismic belt into Sanhe-Laishui segment, Tangshan-Xingtai segment and Anyang-Chengwu segment; Tanlu seismic belt into Kaiyuan-Liaodong bay segment, Bohai segment, Weifang-Jiashan segment and Jiashan-Guangji segment; and Yinchuan-Hetao seismic belt is preliminarily subdivided into Yinchuan segment and Hetao segment. In addition, the problems such as the relation between southern border of Heibei Plain seimic belt and East Qinling-Dabie belt, the identification of seismic belt segments with different earthquake sequence type, e.g., single mainshock type or multimainshock type, and the possible segments with potential strong earthquake, are tentatively discussed.Key words：North China tectonic region；seismic belt; segmentation； mainshock type；multiple mainshock type；strong earthquakes
