摘　　要：本文简要论述了应用最小二乘配置原理、利用GPS观测资料,建立基于不同参考基准和不同运动学与几何变形含义的地壳运动模型及不同空间分辨率应变场的方法。同时,结合中国地壳运动观测网络区域网和有关GPS连续站观测资料的处理与分析,从GPS观测能够直接获取地壳相对运动和反映研究区域几何变形时空分布状态,讨论了关于地壳运动动态与强震关系的问题。In this paper, the method of modeling crustal movement and obtaining different spatial strain field is briefly introduced. This method uses GPS data and least square collocation. It is based on different reference benchmark, different kinematics and geometry deformation. In the meantime, the data used include regional network and permanent station of Crustal Movement Observation Network of China. Finally, the relations between crustal movement and strong earthquake are discussed. The relations include the crustal movement obtained by GPS survey data and the timespatial distribution of geometry deformation in the investigated region.
