| 摘 要： | 为了高效率、高精度地获取活动构造研究中的定量参数,引入数字航空摄影测量学方法十分必要.在川西地势陡峻的鲜水河断裂带上进行了试验性研究,探讨了测量精度和效率,总结了工作流程与操作方法.利用空间信息增强的正射纠正影像、大比例尺地形图和地形剖面图,获得康定南团结乡附近鲜水河断裂带康定段断层迹线的空间分布,量测得到该断裂在T1洪积扇形成以来左旋水平位移量为43m,垂直位移量为5.8m.结果表明,利用数字航空摄影测量学方法进行活动构造地貌研究中水平累积位移量、垂直累积位移量、断层长度等定量参数的测量以及构造几何学精细解析与构造地貌成图完全能满足精度要求,大大提高了野外工作效率,是活动构造定量研究的一种有效的技术方法.

| Abstract: | In order to efficiently obtain high-quality quantitative parameters in active tectonics research, it is necessary to introduce digital aerophotogrammetry as a surveying and mapping tool. Testing research was performed along the Xianshuihe fault zone, which is located in the mountain area of western Sichuan Province. Using spatially enhanced, orthorectified images, large scale topography and ground surface profiles, we obtained a series of data of the active Xianshuihe fault zone near Tuanjie in the south of Kangding county. Left lateral horizontal deformation of the fault is about 43 m and vertical deformation is about 5.8 m since the T1 proluvial fan was formed. Digital aerophotogrammetry provides high precision when measuring quantitative parameters in the study of active tectonics such as accumulative horizontal and vertical deformations and fault length, detailed geometric structure resolution and geomorphological mapping, thus greatly improving field work efficiency. |
