The temperature and the doping concentration dependences of the equal time spin correlation, S(Q), are calculated by a quantum Monte Carlo method, and are analyzed by introducing a doping-dependent intrinsic correlation length and a thermal correlation length in a phenomenological way. This provides a unified picture of the spin correlation in the small-doping and low-temperature region.
