In order to clearly understand the dynamics mechanism about broad-leaved Korean pine forest and simulate its dynamics mechanically, a simulation model is demanded through which we can simulate the long-term dynamics of BKPF under different pine cones picking intensity and hunting for grey squirrels in different intervals. By considering the effective dispersal of seeds by animals, the human disturbance and the masting behavior of Korean pine, a new gap model integrated seed-bank and regeneration dynamic model, based on the classical gap model, is established.
