摘要
介绍了福建省地壳形变观测网络的建设。福建省地壳形变观测网络 ,以GPS观测技术为主 ,结合精密水准、精密重力和流动地磁测量 ,将 3者重合到GPS观测基准站上获取观测信息 ,初步构成一个时空相结合 ,点线面与长中短兼顾的高精度、高时空分辨率的地壳形变观测网络。该网络可动态监测福建省东南沿海地区地壳运动变化 ,为地震预测预报提供背景信息 ,将取得显著的社会效益和经济效益。
In the crustal deformation observation network of Fujian province,whose building is reported in this paper, the observational information is measured with the GPS technique as the principal means and combining with precise leveling,precise gravimetry and geomagnetic survey.Thus this network is of a temporal and spacial combination,high accuracy and high resolution,it is integrated by dot,line and plane in space domain and it takes the all precursors monitoring in long,medium,short and impending term into account.This network can dynamically monitor the crust movement along coast of Fujian province and provide the background information for earthquake prediction and can consequently bring us enormous benefit in the economic and social field.
