| 摘 要： | 根据最近十年来三期复测精密水准资料，分析了辽宁地区近期地壳垂直运动的演化状况，结果表明辽宁地区在１９８４年－１９８９年期间表现为整体范围的隆升，且没有明显的原有继承性运动特征，这反映了应力应变在加强；１９８９年－１９９３年则显示出该区已处于应力应变的调整与恢复状态之中，其运动性质也体现为以继承性运动为主。辽宁地区的这一运动过程与华北北部地区的运动过程是相一致的。目前该区域内的差异运动量值偏大。

| Abstract: | The according recent development of vertical crustal movement in Liaoningarea is analysed to the preclse relevelling data in three time. The results show that Liaoningarea uplifts wholly during 1984-1989,and the eastern part and the western part of Liaoningarea uplift and the middle of liaoning area subsides from 1989 to 1993.These also showLiaoning area had been in strain accumulation before 1989 and has been in strain recovery af-ter 1989 simultaneously.The feature is possibly related to Datong earthquake. |
