摘要： 空间定位技术GPS 可以达到很高的相对定位精度(10~(-6)～10~(-8)),是监测地壳运动、进行地震预报的一种新手段。中国华北是一个地震活跃地区。应用GPS 技术在华北布设了一个地震监测网,经过精心观测、优化设计和严密平差,获得了高精度的第一期成果。华北GPS 网的建立将为大震预测和地球科学各领域的研究提供重要的科学依据。

Abstract: Space positioning techniques by using GPS can give high re-lative positioning precision(10~(-6)～10~(-8)),and is a new method to monitorcrustal movement and forecast the earthquake.North China is an activeseismic region where earthquake frequency and its intensity are high.Byusing GPS,an earthquake monitoring network is established in NorthChina.Based on meticulous observation,optimum design and close adjust-ment,a first group of results with high precision are obtained.Establi-shing of GPS network in North China will form an important scientificbasis forecasting of heavy earthquake and studing of the earth.
