| Abstract: | The method for calculation of crustal visual strain field using diversified deformation data (GPS, spanning fault, etc.) and combining fixed point strain data is studied. It contains that the homogeneous visual strain inside element is computed by the indirect adjustment and the continuous distribution of horizontal visual strain is calculated by the least squares collocation. Moreover, we compute and analyse the data of the GPS monitoring network in North China in 1992,1995 and 1996, and obtain the dynamic pictures of visual strain field. |
