以闽南地区为研究区域，以ETM＋遥感影像数据为基础，通过广泛收集、分析研究区地质背景资料，分析区域内断层活动情况，进而提取研究区线性构造信息，结合地震地质资料对闽南地区主要断裂的分布情况及活动性做系统的分析研究。同时对闽南地区的新构造活动及构造应力场，线性构造和水系的分形分维，地震活动及其危险性和地热异常等主要影响因子做初步探讨。在确定影响断裂活动性的主要因素后，对研究区进行初步分区和定量化评价。最终判定研究区可圈定为：相对较不活动区、相对较活动区、相对活动区3个活动性级别。其中相对活动区面积占整个研究区3／5以上；相对较不活动区面积较小，造成相对活动的关键性因素是地震、活动断裂。

Taking Minnan area as a research area, based on ETM ＋ remote sensing image datas, through collecting and analyzing geological background information, analyzing the activities of the faults, extrac- ting linear structure information, and combining with earthquake geological datas, distribution and activi- ties of main fractures in Minnan region have been analyzed and studied. Genozoic and recent techonic activ- ities, the crustal surface, fractal dimension of linear structures and river system, seismic activities, risks and geothermal abnormity have been studied primarily. Based on active analysis and fuzzy comprehensive evaluation, the active grade of each subzone in Minnan area has been determined. The research area can be finally circled into the relative not activity region, comparative activity region and the activity region. The relative activity region of area is more than three of five of the whole research area. The relative not activi- ty region is smaller. The key factors which caused realive activity are earthquake and active faults.
