中巴地球资源卫星数据在地震活断层研究中的应用——以巴里坤断裂带为例
|
摘要
本文利用中国自主研发的中巴地球资源卫星CBERS-02的CCD数据,对新疆东天山巴里坤活动断裂带进行了研究。针对CBERS-02的CCD数据特点和地震应用的需求对遥感数据中有关洪积扇期次、断层和阶地的信息进行了增强,在对这些增强信息判读和分析的基础上将巴里坤断裂带分为东(东盐池-巴里坤断裂带)、西(西盐池-东盐池断裂带)两段,根据对每段断裂带微地貌的遥感解译划分了各段的次级断裂。结果表明,CBERS-02的CCD数据能够应用于地震活断层的研究中。
The China Brazil Earth Resources Satellite(CBERS) is a satellite that mainly developed by China.This paper discussed the application of CBERS-02 CCD data to the study of the Balikun active fault zone in Xinjiang.Based on the features of these data and the need of earthquake application,first we use apparent reflective technology and principle component analysis to enhance information of active fault,the periods of alluvial fans and terrace.Then we divided the fault zone into two parts(the east Yanchi-Balikun fault zone and the west Yanchi-east Yanchi fault zone) according to the above analysis,and further divided each fault zone into sub-faults according to micro-geomorphology.The results of this study shows that CBERS-02 CCD data can be used in the study of earthquake active faults.
