  In this paper, we investigate the global regularity of 2D generalized MHD
equations, in which the dissipation term and magnetic diffusion term are
$\nu(-\Delta)^\alpha u$ and $\eta (-\Delta)^\beta b$ respectively. Let $(u_{0},
b_{0})\in H^{s}$ with $s\geq2$, it is showed that the smooth solution
$(u(x,t),b(x,t))$ is globally regular for the case $ 0\leq\alpha\leq\{1}{2},
\alpha+\beta > \{3}{2}$.
