摘要
First, a theoretical model of density of cuttage seedlings on poplar was evaluated by using mathematical tools based on anatomy and morphology of photosynthesis organ, then,according to this, an afforestation density of the trces was put forward, finally, the importance,scope and method of the theoretic application wcre described through a concretc calculation. The result showed that these density models had not only rigorous theory base, including biology and mathematics, but also wide applying prospect. And at the same timc, the model parameters could be gotten easily in forestry practice.
