本文主要是利用水准复测资料来阐述某地区的现代升降运动。文中将复、初测高程进行比较,作出了现代地壳运动幅度图,图中看出东都上升幅度小,速度梯度变化也小;西部上升幅度大,速度梯度变化也大。在整个剖面中更可以看出,在较短距离内出现大幅度的隆起,隆起中又有相对凹陷。由实际资料得出,本区现代地壳运动有继承性,并出现三种类型的上升运动:(1)平稳的上升运动;(2)掀斜的上升运动;(3)强烈隆起。
This article is mainly the use of level retest data to illustrate a region of the modern movements. In the paper, comparing the complex initial test with that of the initial test, the amplitude of the modern crustal movement is made. The figure shows that the increase of the east is small and the change of the velocity gradient is also small. The increase of the west is large and the change of the velocity gradient is also large. It can also be seen in the whole section that there is a large uplift in a short distance and a relative depression in the uplift. According to the actual data, the modern crustal movement in this area has inheritance and three types of ascending movements appear: (1) steady ascending movement; (2) ascending ascending movement; and (3) strong uplift.
