The quantum entanglement dynamics of a one-dimensional spin-1/2 anisotropicXXZ model is studied using the method of the adaptive time-dependentdensity-matrix renormalization-group when two cases of quenches are performedin the system. An anisotropic interaction quench and the maximum number ofdomain walls of staggered magnetization quench are considered. The dynamics ofpairwise entanglement between the nearest two qubits in the spin chain isinvestigated. The entanglement of the two-spin qubits can be created andoscillates in both cases of the quench. The anisotropic interaction has astrong influence on the oscillation frequency of entanglement.
