摘　　要：笔者描述了1996年2月3日丽江7．0级地震的地震烈度、极震区房屋震害、地表破坏等地震灾害分布的不均匀性特征，并分析了震害分布不均匀性的主要原因是由发震构造破裂方式、活动断裂、巨厚的新沉积层、地形地貌、地基基础等多种因素的影响所造成。This paper interprets the uneven distribution of the earthquake damage of the 7.0 scale quake in Lijiang on Fed 3,1996, including earthquake intensity, earthquake damage of building in extreme seismic area and surface damage, etc. We regard the multi factor intiuence of broken form of earthquake origin istructure, active fault, thick new sediments, geomorphic feature and building base, etc as the main cause of the uneven distribution of the earthquake damage.
