摘要: 利用长江三角洲区域内19个GPS连续运行参考站2007～2013年间的观测数据,计算得到了该区域ITRF2005参考框架下的三维速度场、应变参数及区域参考框架下的速度场。结果表明,在ITRF2005框架下,水平方向平均速率为33.97 mm/a,优势方向为NE 111.5°;相对于欧亚板块的水平方向平均速率为9.36 mm/a,优势方向为NE 85.6°;高程方向以沉降为主,最大沉降速率为15.22 mm/a,平均沉降速率为4.7 mm/a;该区域块体以N 29.4° E的拉张为主,达到2.4×10-9/a,同时兼有N 119.4° E的挤压,达到1.3×10-9/a。Abstract: The GPS observations from 19 continuously operating reference stations distributed in the Yangtze River delta area from 2007 to 2013 were processed using the GAMIT/GLOBK software package, and the estimated coordinate time series were used to determine the velocities of reference stations in the ITRF2005 frame. Strain parameters and velocities relative to the Eura-Plate were also estimated. These results show that Yangtze River delta area moves at 33.97 mm·a-1 in the NE 111.5° direction in the ITRF2005 frame, while the average horizontal velocity relative to the Eura-Plate is 9.36 mm·a-1 in the direction of NE 85.6°. In the vertical direction, the maximum subsidence rate is 15.22 mm·a-1, and the average rate of subsidence is 4.7 mm·a-1. The maximum extension rate is 2.4×10-9/a and with the compressing rate of 1.3×10-9/a in the direction of N 119.4° E.
