Abstract: Through solving the Laplace equations about physics co ordinate to transform plane,a numerical method of determining the grid points had been successfully used to generate the orthogonal co ordinate system.the disposal means of the boundary condition & the numerical method for the two connexity area had been advanced .The means obtained the preferable effect for generation of the orthogonal co ordinate system in the Meizizhou reach.

Key words: Laplace equations, the orthogonal co ordinate system, the two connexity area
