福建沿海地壳运动与GPS测量结果初步分析

The primary analysis on crust movement and GPS survey results in Fujian inshor

为监测北东和北西向断裂带的活动性以及水口库区因蓄水所诱发的地壳形变,而在福建沿海建立的由12个测点组成的GPS监测网,迄今为止,进行了2次联测,一次在1995年,一次在1997年。本文对这2次的观测概况、数据处理以及精度分析作了较详细的介绍,并对福建沿海地壳水平位移场特征及其动力学机制进行了探讨。

For monitoring the activity of NE and NW seismic faults as well as the curst deform induced by the sluice in Suiko reservoir area, we set up a GPS monitoring network composed of 12 observation sites in Fujian inshor, Up to now, we carried out 2times connect observation. One time was in 1995, another time was in 1997. In this paper, it was introduced in detail that the general situation, date disposal and precision analysis of the two times observations. And we also probed into the characters of crust horizontal displacement field in Fujian inshor as well as its dynamic mechanism.
