| 摘 要： | 本文以１９８２－１９９１年滇西实验场及外围地区跨断层短基线（水平）、短水准（垂直）的监测资料为窗口，讨论了场区现今构造活动是以水平位错为主，同时滇西北东构造带以北地区应力场方向自１９９０年以来发生了变化（近南北向），认为一趋势变化可能是未来地震形势的转移。

| Abstract: | Taking the data of fault-crossing short-base(horizontal) and shortlevelling(vetical) observed in WYEPSA 1982-1991 as a window, the modrn tectonic movements in the WYEPSA have been studied. The study showed that horizontal dislocation was dominant, the direction of stress field in north-east belt of West Yunnan had changed since 1990 which could be considered as the transition of the future seismic tendency. |
