摘　　要：采用澜沧－耿马地震前后两期大地测量资料，结合发震区的地质资料和震后地表形变破坏带的调查资料，运用顾及参数先验信息的贝叶斯反演方法，联合求定了澜沧－耿马地震的两个发震断层的位错模型参数。In this paper, the Bayesian inversion method, which considers the prior information of parameters, is used to determine the parameters of the dislocation models of Lancang and Gengma earthquakes by using geodetic and geological data. The stress drop calculated by the obtained dislocation models is of the same magnitude as that calculated by the seismogram.
