用多源遥感数据解译深圳市主要活断层

Identification of Major Active faults in Shenzhen Using Multi-style Remote Sensing Data

利用SPOT-5、ETM^＋等多源遥感数据和DEM数据，通过遥感解译，结合现场调查验证，初步查明深圳市主要活断层主要有NE向，NW向两组，从属于东南沿海构造体系。其中NE向的深圳断裂带为主要构造。进一步分析了这些断层的空间展布及其分段性，断层的活动性特征等。研究表明，多源遥感数据可以有效应用于深圳市城市活断层探测的初勘阶段，为进一步的活断层危险性评价提供了参考依据。

Using multi-style satellite images including ETM^＋ ,SPOT-5,CBERS-01/02,Envisat-1 and DEM data, and based on previous studies and field investigation , this paper introduces the interpreting results from remote sensing data. It is found that there are two groups of active faults of extending in the directions of NE and NW respectively in the city of Shenzhen. The main tectonic zone is the Shenzhen fracture system including Jiuweiling fault, Henggang-Luohu fault and Liantang fault, which belongs to the Lianhuashan fault zone in southeast coast. The paper also discusses the spatial distribution and segmentation character and activities. It is concluded that using multi-style remote sensing images in preliminary investigation of Shenzhen city active faults is useful for next step detection work.
