摘　　要：选取与油松蓄叶量相关的年平均高生长、冠幅、轮枝层数、危害龄4个因子,推导出多元非线性方程。利用微机,采用逐步回归的方法建立了数学回归模型,并在两个样本的实际应用中达到了较高的精度,此模型解决了松毛虫对油针枝叶危害达到任意水平时的蓄叶量计算问题。Annual average height growth (A), tree crown width (B), crown lager number (C), and the damaged needle age (D) are four factors relative to leaf storage capacity of Chinese pine. A multivariate non-linearformula was inferred by using cumputer. It reached high accuracy whenactually practised. The model solves the problem of leaf storage capacitycalculation no matter how the pine needle was harmed.
