Abstract：
The momentum distribution of multiparton system is derived from PQCD in Lund model, whileits color string configuration among parlous is assigned by phenomenological model. Using recursive formulation of matrix elements for e⁺e^－→m (qq)+ng, the effective Hamiltonian is found and some of its properties are given as the basis for the study of color interaction and color string configuration among partons.
