摘要
采用Logistic方程模拟，揭示了沙棘（Hippophae rhamnoides）、刺槐（Robinia Pseudoacecia）、山杏（Prumus armeniaca）等10个树种的生长发育特性．以试验数据分析了造林密度、施肥、平茬与灌木林产量的密切关系．
By using the Logistic simulation method, the results indicated the growing anddeveloping characteristics of ten kinds of trees such as Hippophae rhamnoides,Robinia pseudoacecia and Prumus armeniaca. The close relationship among afforested density,fertilizeramount,felling and shrubbery production was analyzed.
