摘　　要：据分形理论，系统地研究了滑坡活动时空分布的信息维（Ｄ１）特征。从滑坡活动信息维的变化特征看，在信息维的急剧变化阶段，对应着一个滑坡活动的高潮期，分维的变化真实地反映了滑坡活动的动态演化过程，降维现象可作为滑坡时间预测的判据。The information dimesion(D1) characteristics of the temporal and spatial distribution of landslide activities are systematically studied based on fractal theory. The results show that a sudden variation stage of information dimensions coincides with the climax period of landslide activities. The variation feature of information dimensions reflects genuinely the evolutionary trends of landslide activities. The phenomenon of fractal dimension dropping can be taken as a criterion to the temporal prediction of landslide activity.
