摘　　要：归纳了华北地区的新构造特征,划分了4个基本新构造类型和16个次级类型.给出了在新构造类型划分基础上进行新构造分区的5条原则和华北新构造分区的两级划分方案,共划分11个一级区和37个二级区.从潜在震源的新构造背景、分区边界、分区步骤等方面讨论了潜在震源与新构造区的关系.提出了在新构造区的基础上直接划分潜在震源的可行性与合理性.The neotectonics in North China has been divided into 4 fundamental structural types and 13 second- order structural types based on the neotectonic features. The paper gave 5 principles and two-stage division program of the neotectonic regionalization and the North China area may be divided into 11 first -order areas and 37 second -order areas. There lations between the potential source areas and neotectonic regions have been discussed from the neotectonic setting, regionalization boundaries and regionalization procedures of the potential source areas. It is feasible and reasonable to direct divide the potential source areas based on the neotectonic regions.
