| 摘 要： | 利用Landsat 8、Google Earth等中高分辨率遥感影像以及ASTER GDEM资料并结合前人研究成果,在分析总结江西九江及邻区主要活动断裂带遥感影像解译标志的基础上,获取该区主要活动断裂空间展布情况,结合地震地质资料进一步探讨该区主要活动断裂的性质及其第四纪活动性。研究发现,该地区断裂构造空间展布复杂,以北东与北西走向为主,其中的主要活动断裂带可归并为4大断裂系统,分别为庐江—广济断裂系、黄冈—鄱阳断裂系、九江断裂系和东至—鄱阳断裂系。根据主要断裂带的地貌错位、三维地貌与地形信息及历史地震数据等对断裂活动性进行分析和分级,将该区主要断裂的现今活动性划分为显著、较显著和一般3个级别,并进一步讨论了区域断裂活动与地震的关系。

| Abstract: | This paper summarized interpretation marks of the main active fault zone in Jiujiang and its adjacent areas to obtain the spatial distribution of the main active faults using the Landsat 8, Google Earth and other moderate-high resolution remote sensing images and ASTER GDEM data combined with previous studies. At the same time, the nature of the main active faults in the area and the Quaternary activity were discussed on the basis of seismic geological data. It is found that the spatial distribution of fault structures in this area is complex, with NE and NW oriented, and the main development active fault zones are divided into 4 fault systems, including Lujiang-Guangji fault system Huanggang-Poyang fault system, Jiujiang fault system and the east Poyang fault system. According to the landform dislocation, 3-D landforms and terrain information and historical earthquake data of the main active fault zones, the activity of faults are analyzed and classified.The activity of the main faults in this area are divided into 3 different levels, which are remarkable, moderately remarkable and general, then further discusses the relationship between earthquake and the regional seismic activity. |
