| 摘 要： | 采用分段线性速率动态平差法处理了关中地区７０年代以来的多期垂直形变资料，在此基础上，通过垂直形变场图像，数字特征量和曲面数字特征，定性、宣地分析了该区垂直形变场演化情况。指出，关中地区目前处于垂直形变差异较弱的继承性运动状态，并对这一现象作了探讨。

| Abstract: | Processing the polyphase vertical de formation data in Guanzhong area after 1970s by using the method of segmental linear rate dynamic adjustment, through vertical deformation field pattern, field numerical characteristic's quantity and curved surface numerical features, the authors analyse the evolutionary situation of vertical deformation field in this area qualitatively and quantitatively, and point out that Guanzhong area is situated in the state of inherited movement whose vertical deformation divergence is weaker. In addition,the authors also simply discuss this phenomenon. |
