| 摘 要： | 本文以白榆（Ｕｌｍｕｓ ｐｕｍｉｌａ）为例，对无深裂痕阔叶树种叶面积的确定提出了一个较为适合的线性模型，并采用主成分回归的方法处理模型中的复共线性问题，认为该类叶片的叶面积主要受“叶面积综合因子”和“叶缘曲线与抛物线的偏离程度”的影响。

| Abstract: | This Paper, using Ulmus pumila as an example to survey the leaf area of broad-leaved trees leaf hasn't deep rift, raised a su itable linear model, using the method of principal component regression, dealt with the compound multi-collineriity questions of this model, indicated that the leaf area of thess leaves are mainly subjected to" comprehensive factors of the leaf area" and " leaf edge curve and the deviated level of parabola". |
