摘要
对北京地区多期精密水准资料进行同网形、同方法和同起算点的平差处理,采用曲面拟合的方法绘制了从60年代至90年代的地壳垂直形变速率图。系统地研究了北京地区30余年的趋势性形变特征和各地震活动时期不同时间段内的地形变特征。其研究成果不仅对地震预报研究而且对理论形变场等地学问题均具有一定的意义。
Theprecise Ieveling data for several perid in Beijing area have been adjusted by using samecalculated method for uniform leveling network and from the same initial point.The maps of ver-tical crustal deformation rate from 60's to 90's have been drown on microcomputer using curvefiting method. The features of crustal deformation,including its long-term tendency and featuresfor each seismic episod during more than 30 years have been also systematically studied in Beijingarea.These results offer some important clue to both seismic prediction study and the theoreticaldeformation field.
