综合前人资料分析了川—滇构造带及其邻区地壳－上地幔速度结构与地震分布的关系。结果表明，川—滇构造带具有同青藏高原地壳－上地幔结构相似的某些特征；地震活动主要沿安宁河断裂带和小江断裂带分布。震源以永仁、渡口和会理三地所在区域最浅，向四周渐深
Based on the previous data, the relationship between the velocity structure and the distribution of the crust and upper mantle velocity in the Sichuan-Yunnan tectonic belt and its adjacent areas was analyzed. The results show that the Sichuan-Yunnan tectonic belt has some features similar to the crust-upper mantle structure of the Qinghai-Xizang Plateau. The seismic activity is mainly distributed along the Anninghe fault zone and the Xiaojiang fault zone. The source of Yong Ren, Ferry and Hoi Li three areas are the most shallow, gradually deepening around
