【 摘 要 】

Based on the atmospheric turbulence diffusion model, a three-dimensional numerical model was applied for predicting the cross-pollination rate distribution in leeward area of windbreaks by considering actual weather observation data, daily fluctuation parameter of pollen release rate, pollen life during flowering period, etc. Several cases of cross-pollination effect of windbreak distributions in the field were simulated. It is demonstrated that windbreak nets and windbreaks plant or forest are effective in suppressing pollen dispersal and cross-pollination. By simulating pollen diffusion under actual weather conditions using this model, it is possible to evaluate the effect of cross-pollination by the windbreak facilities and give advises of how to set windbreaks for suppressing crossing.
