| 摘 要： | 探究两种计算叶面积的方法,用数理统计的方法,以叶长、叶宽、长×宽、面积等作为指标,求出叶面积和长×宽的回归方程;利用叶片形状系数计算叶面积。通过计算结果比较,指出用回归方程计算更精确、更合理。

| Abstract: | Two method of calculate leaf area were used by statistics,a study was conducted to estimate leaf area of garden kinds of trees using regressive equation.The leaf area estimation were found to be signficantly correlate with figure coefficient,There were most significant positive correlations between the the leaf area and lenth times width;was leaf area estimated by figure coefficient,calculate result showed that the calculate method of regressive equation is more suitable and more accurate. |
