摘　　要：We have studied the centrality dependence of charged-particle forward-backward multiplicity correlation strength in Au+Au collisions at sNN1/2=200 GeV with a parton and hadron cascade model, PACIAE, based on PYTHIA. The calculated results are compared with the STAR data.We have studied the centrality dependence of charged-particle forward-backward multiplicity correlation strength in Au＋Au collisions at SyN1/2=200 GeV with a parton and hadron cascade model, PACIAE, based on PYTHIA. The calculated results are compared with the STAR data. Theexperimentally observed correlation strength characteristics, （1） the approximately flat pseudorapidity dependence in central collisions and （2） the monotonous decrease with increasing centrality,
