构违地貌是地壳构造运动的产物。构造地貌类型及其特征由各种形式的地壳构造活动所控制。沂沭断裂带是一条典型的构造地貌带。本文试将沂沭断裂带的构造地貌划分为地堑地垒式构造、蛇曲形水系、断陷盆地、断层三角面和断层陡崖、断褶山及玄武岩火山地貌等六种类型。构造地貌与地震的关系密切,研究这种关系,将对地震危险区段标志的寻找提供新途径。 Landslides are the product of crustal movement. Tectonic landform types and their characteristics are controlled by various forms of crustal tectonic activity. Yishu fault zone is a typical structural belt. In this paper, the tectonic geomorphology of the Yishu fault zone is divided into six types, namely, the graben-style structure, serpentine water system, fault basin, fault triangle and fault cliff, fault fold mountain and basalt volcanic landform. The relationship between tectonic landform and earthquake is closely related. Studying this kind of relationship will provide a new way to find the sign of danger zone in earthquake.
