中文摘要：

自然灾害不仅会给人的生命财产带来巨大损失，而且还易衍生各种群体性事件。研究灾害衍生型群体性事件，探讨特定的灾害情境及群体性事件要素的异化，构建灾害衍生型群体性事件的演化模型，明晰事件的演化特征，可以从动态角度分析自然灾害与群体性事件之间的衍生关系，实现对灾害衍生型群体性事件的全景式展现，拓展我国群体性事件的研究思路，为灾害衍生型群体性事件的有效处置提供针对性策略。

英文摘要：

Natural disasters will result in heavy losses of life and property as well as various mass inci-dents.We can analyze the derivative relationship between natural disasters and mass incidents from a dynamic perspective：i.e.to discuss certain disaster situations and the alienation of elements in mass incidents;to build the evolutionary model of mass incidents derived from natural disasters;and to de-fine their evolutionary characteristics.On this basis, we will get a panoramic view of how mass inci-dents derive from natural disasters, and enrich our ideas for studying mass incidents in China, thus of-fering pertinent strategies to effectively deal with those incidents.
