Two-particle distributions are investigated in the multi-peripheral model which has succeeded in fitting single-particle distributions. In this article the two particle distribution functions in the pionization region are investigated. Our results show that there is a cutoff with respect to k_<1bottom>^2,k_<2bottom^2 and (k_<1bottom>^2,k_<2bottom)^2, where k_1 and K_2 are four momenta of produced particles. Our results indicate that the correlations are stronger in ππ than in KK^^--channel and the correlation has the k_bottom^2 dependence. In other words the stronger correlations are seen in the small k_bottom^2 region than in the large k_bottom^2 region. Comparison with the experimental data on longitudinal rapidity distributions and rapidity correlations are also discussed. The qualitative features agree with our result.
