| 摘 要： | 以1982－1995年云南中部地区跨主要断裂短基线（水平）、短水准（垂直）的监测资料为窗口，经数模计算和反演，讨论了该区现今构造活动性及构造形变应力场特征。其结果表明，该区现今构造活动是以水平位错为主；川滇菱块南部边界断裂扭运速率高于块内其它断裂，并显示了向南南东滑移兼抬升的活动趋势。

| Abstract: | The modern tectonic activity and deformation stress field in Mid-Yunnan region is discussed by the windows of data observed in short base line(horizontal)and short leveling(vertical)across the major fault in 1982-1995 through DA calculation and inversion.The results indicate that the horizontal dislocation takes the leader in the modern tectonic activity.The twisting speed of the bordering fault in the south of the Sichuan-Yunnan Diamond Block is higher than that of other faults.It indicates an active tendency slipping towards SSE and uplift. |
