### Abstract

We study the topological feature in the QCD vacuum based on the hypothesis of abelian dominance. The topological charge Q_{SU(2)} can be explicitly represented in terms of the monopole current in the abelian dominated system. To appreciate its justification, we directly measure the corresponding topological charge Q_{Mono}, which is reconstructed only from the monopole current and the abelian component of gauge fields, by using the Monte Carlo simulation on SU(2) lattice. We find that there exists a one-to-one correspondence between Q_{SU(2)} and Q_{Mono} in the maximally abelian gauge. Furthermore, Q_{Mono} is classified by approximately discrete values.
