Abstract: This paper briefly introduces the GPS (Global Positioning System)field surveys for crustal deformation in North China in 1995 and 1996,the processing of the observation data with the Bernese software,results of the horizontal displacements,strain and the vertical displacements The implications of the tectonic movement are analysed seismogeologically and it is suggested that the horizontal crustal deformation observed by GPS may reveal some information of activities of upper crust blocks

Key words: GPS, Crustal deformation, North China

摘要: 简要介绍了华北地区GPS形变监测网1995~1996年两次观测概况,利用伯尔尼软件进行数据处理的主要过程、水平形变计算与应变分析的方法和结果及垂直形变的结果。分析了GPS成果的地震地质意义,认为GPS观测到的水平形变可能反映了上地壳层块构造活动的某些特征。
