The Hermite-Hadamard type inequalities for （ h - m）- convex functions on the bi-dimensional co-ordinates is established in this paper, which are generalizations of the Hermite-Hadamard type inequali- ties for concex functions,s-convex fucntions（in the second senee） , m-convex functions and h-convex func- tions on the bi-dimensional co-ordinates.%建立了二维依坐标（h-m）-凸函数的Hermite-Hadamard型不等式，推广了二维依坐标凸函数、二维依坐标s-凸函数（第二种意义下）、二维依坐标m-凸函数与二维依坐标h-凸函数情形下的Hermite．Hadamard型不等式．
