摘要
中国经向构造带以往大多强调其挤压性与张性特征，近年发现其扭性也具普遍性。在中国西部，作者选取川滇经向构造带中的西昌一元谋断裂、南澜沧江断裂为例，综合该区广泛发育的旋扭构造、反多字型等派生构造，提出了该区经向构造带总体上呈右型扭动；在中国东部作者以山西陆台东西侧的ＳＮ向构造为例，依据其派生的多字型、旋扭构造，结合出现在东部平原区的实际现象，指出其主要为左型扭动。作者将中国经向构造的东左西右扭动，名为“竖移运动”。这对于研究矿产、地震、地热的分布具有重要意义，也为认识中国大陆总体向南的滑移运动提供了新佐证。
In the past, meridional structural belts in China were mostly described as purely compressional and tensional, but in recent years there have been found evidence to show they have undergone some lateral slip. In west China, they are mostly dextral, and in east China, they are dominantly sinistral. The overall result of such a gliding regime points to a southward movement of the China.
