In this paper,based on Thiele type continued fraction interpolation and barycentric rational inter-polation,we construct Bivariate Barycentric-Thiele type blending rational interpolation. The interpolation theo-rem and the error estimates are given. Through the discussion of the definition of inverse differences,numerical examples are presented to verify the correctness and validity of this method.
