In this paper, we study the weak convergence of the multifractional Brownian sheet of Riemann-Liouville type in Besov space. By using a Poisson process in the plane and the partial sums of two sequences of real independent multifractional Brownian motion of Riemann-Liouville type, respectively, we obtain limit theorems of the multifractional Brownian sheet of Riemann-Liouville type.
