本文利用ETM+、资源三号等多源遥感数据,经过镶嵌、增强及融合等一系列影像处理,对沂沭断裂带(郯庐断裂带山东带)的几何展布及构造地貌特征进行了详细的解译。研究表明,沂沭断裂带总体走向NNE,主要由5条主干断裂组成,分别是鄌郚-葛沟断裂(F_1)、沂水-汤头断裂(F_2)、白芬子-浮来山断裂(F_3)、昌邑-大店断裂(F_4)及安丘-莒县断裂(F_5),遥感影像上形成两堑一垒的构造地貌格局,而每条断裂均有明显的遥感构造地貌特征,表现为线性特征、色调差异、串珠状湖泊分布、断层陡坎、断层陡崖、断塞塘等现象,其中安丘-莒县断裂(F_5)在构造地貌上具有历史地震地表破裂、断层陡坎与冲沟同步右旋位错等较新的活动现象,表明该断裂为现今5条主干断裂中构造活动性最强的一条,对强震的发生具有明显的控制作用。
In this paper, the multi-source remote sensing data such as ETM + and Resource No.3 are used to describe the geometric distribution and tectonic features of the Yishu fault zone (Shandong belt of Tanlu fault zone) through a series of image processing such as mosaic, enhancement and fusion. Interpretation. The results show that the Yishu fault zone is generally NNE and consists of five main faults, namely Fuling Guogu fault (F_1), Yishui - Tangtou fault (F_2), Fenfenzi - ), The Changyi-Dadian fault (F_4) and the Anqiu-Juxian fault (F_5), and the remote sensing image formed a two-cutting first base tectonic geomorphology pattern. Each of the faults has obvious remote sensing tectonic geomorphology and is characterized by Linear characteristics, color differences, beaded lake distribution, fault scarps, fault cliffs and fault plug ponds. The Anqiu-Juxian fault (F_5) has the characteristics of historical earthquake surface rupture, fault scarp and fault Newer events such as ditch sync dextral dislocation indicate that this fault is the strongest tectonically active one in the five main faults and has a clear control over the occurrence of strong earthquakes.
