摘　　要：城市人为灾害灾变动力机制在认识上有两个层次：表征机制和内在机制。本文以研究内在机制为目标，阐明城市复合生态位位势、城市界面论、城市奇异吸引源、城市增熵等４个方面的人为灾害灾变动力机制，并指出了这些研究结论的意义。On dynamic mechanism of urban man-made hazards there are two cognitive levels: appearance mechanism and inherent mechanism. To study the inherent mechanism, this paper expounded the four dynamic mechanisms of man -made hazards,i. e. urban complex niche potential, limit theory, strange attractive source and added entropy, and pointed out the significance of these conclusions.
