北方城市行道树电导率变化的研究

Study on the Change of Electrical Conductivity of Roadside Trees in the North of China

以北方城市常见行道树为试材,研究其不同部位电导率变化情况。结果表明:行道树的树皮和树叶电导率明显不同,在不同采样区也存在较大差异,多数行道树的树皮和树叶电导率在不同采样区间呈现PA>PB>PC的规律性变化;同一树种在不同路段的树皮电导率值与道路车流量变化呈正相关。

Taking roadside trees in the north of china as test material,it's electrical conductivity were measured.The results showed that there was significantly difference in trees along the bark and leaves on electrical conductivity,and tree leaves conductivity were mostly higher than bark,most bark and leaves conductivity showed the regularity of change was PA>PB>PC in different sampling interval;bark conductivity value and the road traffic changes were positively correlate on the same tree species in different sections.
