20世纪云南地区地震活动以极高的频度、强度和成灾率而位居我国大陆之前列。本文通过对过去百年地震活动所做的研究作一总结 ,归纳出一系列关于云南地区地震活动规律及其控制地震孕育发展的地球动力过程的基本认识 ,以期对将要进入的 2 1世纪的地震监测布局、成因研究、预测预报工作有一定的指导作用 In the 20th century, the seismic activity in Yunnan Province was at the forefront of China’s mainland with its high frequency, intensity and disaster-hit rate. This paper summarizes the researches on earthquakes in the past century and summarizes a series of basic knowledge about the laws of earthquakes in Yunnan and the geodynamic processes that control the development of earthquakes in order to monitor the earthquakes in the 21st century to be entered Layout, cause of research, forecasting and forecasting have a certain guiding role
