| 摘 要： | 以区域精密水准重复观测资料为依据，用定性与定量相结合的方法，研究了发生于我国大陆板内的１９９６年丽江７．０级等几次强震过程中区域垂直形变速率、剪切变形率、扩张变形率和体积变化率等形变场多种信息的动态演化特征。结果显示：强震蕴育过程中，区域垂直形变场在空间和时间上均会出现不同程度的非均匀态特征。在此基础上，结合区域构造，进一步研究了判定强震危险区的形变前兆场多种信息异常综合标志，得出了一些用大地形变进行强震预测的初步结论。

| Abstract: | Based on precision releveling data, dynamic evolution features of vertical deformation rate, shear deformation rate, extension deformation and body variation rate are studied qualitatively and quantitatively during the Lijiang earthquake(Ms=7.0) etc.process which happened in China plate in 1996.The results suggest that vertical deformation field appears non- homogeneous state in time and space domain in strong seismogenous, on the basis of processing of regional tectonic,multi-specimens of abnormal information, which determine strong seismic risk region, are studied and obtain some primary conclusion about strong earthquake prediction by geodetic deformation. |
