摘　　要：结合川滇菱形块体的活动特征 ,应用图型动力学的损伤演化诱致突变分析方法 ,研究了川滇地区两条地震带中强地震的损伤演化过程 ,并给出各地震带演化到破坏态的所有可能的各单元初始状态的组合形式图。研究结果对指导该区地震预测实践有一定的积极作用。Using the earthquake activity characters of the diamond block in Sichuan-Yunnan area and the method of the meso-scope damage dynamics and damage evolution, we studied the damage evolution process for mezzo forte earthquakes in two seismic belts. The original combination patterns of all the units which illuminates the postural changes from stability states to catastrophe states were given. All these patterns can direct the earthquake prediction practices in the areas.
