| 摘 要： | 在收集、分析前人研究成果的基础上,参考近年来多次工程场地地震安全性评价的野外调查与分析结果,确定了滇西北及其邻区的地震构造标志,进而在该地区重新划分潜在震源区。在有强震发生的地区依地震重复原则划分潜在震源区并确定其震级上限;对于发震构造明显但没有强震记录的地区,根据发震构造规模和活动性特征,依构造类比原则划分潜在震源区;对于活动断裂分段性研究较为清楚的地方,潜在震源区被划分得更细一些;而在断裂隐伏区,则依据地震活动图像及地球物理异常判断潜在源震区的长轴方向

| Abstract: | Lying on the eastern margin of the Tibetan Plateau, the northwestern Yunnan Province has attracted many tourists all over the world for its beautiful scenery and maltinational cultures. At the same time, however, it is also famous for frequent destructive earthquakes that have caused serious loss of life and properties. With rapid economic development, deficiency of electric power in China has become very serious. Therefore, it is inevitable to build a lot of hydropower stations in southwestern China, where |
