福建地区地壳形变特征研究

ON CRUSTAL DEFOMATION CHARACTERISTICS OF FUJIAN AERA

利用福建地壳运动观测网络和IGS发布的台湾桃园国际基准站的GPS连续观测资料的联合解算结果,分析福建内陆的地壳形变特征,以及海峡两岸最近5年的相对运动状况。研究结果表明:福建内陆的运动状态为南强北弱,东强西弱;海峡两岸由过去的拉张变为挤压状态,并且北部与南部存在差异性运动。

By use of the joint solution results of the GPS continuous observation data from the crustal movement observation network in Fujian and Taiwan Taoyuan IGS international fiducied station publicated by the crustal deformation features of Fujian inland, and the relative movements between the both sides of the Taiwan strait during the last five years, it is indicated that the movements of southern and easeeru Fujian inland are stronger than those of north and west Fujian ;the extensional state of the Taiwan strait becomes compressive state,and there is differential movement between the south and north Fujian.
