Abstract：
The mean multiplicities of mesons π^±、π⁰、K^±、K⁰_s、ρ⁰.K^*0、K^*±、φ and baryons p、Ξ^±、Σ^±(1385) are measured for the first time in J/ψ region with 200,000 J/ψ events collected by the BES detector. The results are compatible with LUND and Shandong phenomenological models. Based on the experimental results, the strangeness suppression factor s/u and spin suppression factor V/(V+P) are calculated to be ～0.3 and ～0.3—0.5 respectively, in good agreement with those given by ARGUS Collaboration in region. This indicates that the SU(6) breaking is consistent in the energy region from J/ψ to .
