| 摘 要： | 研究了1976年龙陵7．3、7．4级地震震区内的龙陵-瑞丽断裂、怒江断裂和腾冲断裂的第四纪构造环境和断裂活动性，得出腾冲火山断裂带具有新生火山、断裂构造作用，并对龙陵-瑞丽断裂、怒江断裂等的活动性产生影响和改造。提出了这一活动构造带内小型北西-北北西向断裂是龙陵强震发震构造的观点。

| Abstract: | There are three faults: the Longling-Ruili, Nujiang and Tengchong faults in the Longling area where the earthquakes with M7.3, 7.4 occurred in 1976. We studied their tectonic environment and activities in Quaternary Period. The result shows that the Tengchong-Longling volcanic-seismic belt has neogenic tectonization and it affects the activities of the Longling-Ruili and Nujiang faults. It is thought that the NW-or NNW-trending faults in the Tengchong volcanic-seismic belt should be the seismogenic structure of the 1976 Longling M7.3, 7.4 earthquakes. |
