| 摘 要： | 根据杨树光合营养器官的形态解剖特征、应用数学方法，推导出杨树扦插理论模型，再换算求解出造林密度模型。应用实例表明，两模型既有严格的理论基础、又容易取得模型参数，且计算简便，易于生产采纳。

| Abstract: | First, a theoretical model of density of cutting seedlings on poplars wasevaluated by using mathematical tools based on anatomy and morphologycharacters of photosynthesis organ. Then. according to this. an afforestationdensity of the trees was derived. The result shows that these density models havenot only rigorous theory base. but also widely applied prospect. And at the sametime. the model parameters can be gotten easily in forestry practice. |
