| 摘 要： | 本文利用动态拟稳平差方法及经典平差方法分别处理了1956-1961年～1978—1983年、1982—1983年～1988年两组垂直形变资料,并绘出垂直形变图,用以分析、说明辽宁地区长趋势垂直形变场及辽南地区近期垂直形变场特征.得出:1.辽宁地区长趋势垂直形变场明显受区域地质构造单元控制.辽东台隆、燕山台褶带相对缓慢上升,下辽河断陷下降,三块主体构造单元均呈向渤海沿岸倾斜的趋势.2.海城地震发生在形变等直线发生转折,不同构造单元差异运动交界地带.3.辽南地区近期垂直形变场出现反向运动,并在岫岩县附近形成一条北北西向强烈挤压带.

| Abstract: | In this paper, a vertical deformation map has been drawn by processing two groups vertical deformation data (1956-1961- - - 1978- 1983), (1982-1983- - - 1988) respectively by means of dynamic imitative stable adjustment and classic adjustment method The analysis shows the long-term vertical deformation field in Liaoning area and the characteristics of recent vertical deformation field in Southern Liaoning region. |
