摘　　要：本文基于上海及其邻区活动断裂构造及有关地区潜在地质灾害特点的研究,论证了上海及其邻区潜在地质灾害的三种基本类型及其构造背景与成因机理;指出:上海及其邻区楔形断裂系统的存在与活动是诱发有关地区潜在地质灾害的主导因素。文中明确指出了上海及其邻区楔形断裂系统的研究在相关地区进行潜在地质灾害评价与预测方面的应用前景与发展方向。On the basis of studies on the active faults and the features of the latent geological calamity in Shanghai and its neighdourhood, the authors demonstrated the three basic kinds of latent geological calamity and their tectonic background and genetical mechanism, pointing out that the existence and movement of the wedge- shaped fracture system in Shanghai and its neighbourhood are the major factor inducing the latent geological calamity in the area concerned; the paper also defines the application foreground and research direction of the studies on the wedgeshaped fracture system in the field of appraisal and prediction for the latent geological calamity in Shanghai and its neighbourhood.
