    The PHOBOS’s limiting fragmentation etc. three empirical scaling rules for
    charged multiplicity in Au+Au collisions at RHIC are investigated by a
    hadron and string cascade model LUCIAE. Similar studies are performed for the meson exploring its production mechanism via comparing with the charged
    multiplicity. The LUCIAE results for charged multiplicity are compatible with
    PHOBOS observations. However, for the  meson the three empirical scaling
    rules are either kept only or kept better in the LUCIAE calculations without
    reduction mechanism of the s quark suppression extra introduced for the
    strangeness in LUCIAE model. These results seem indicating a universal
    production mechanism for charged particle and  meson in string
    fragmentation regime. It is discussed that the PHOBOS’s empirical scaling
    rules are model dependent indeed.
