| 摘 要： | 以北方常见的9种行道树为试材,研究了树皮和树叶pH值的变化规律和趋势。结果表明:行道树的不同树种间pH值存在较大差异;同一种行道树树皮和树叶的pH值在不同方位存在显著差异,但2个部位pH值变化规律不一致,且二者之间没有显著相关性;行道树的树皮pH值与道路机动车流量呈显著的负相关性。

| Abstract: | The pH value of nine urban roadside trees grew in the north of China were measured.The results showed that the pH value existed great variation among nine species of roadside trees in Handan downtown;Though the analysis of variance,bark and leaf's pH value were significant different among different position for the same roadside tree;the relationship between pH value of tree bark and urban automobiles flow quantity was remarkably negative correlation;nine species of roadside trees,no significant correlation... |
