青州市8种行道树夏季叶滞尘能力的研究

Study on Dust Retention Ability of Leaves of 8 Street Trees in Qingzhou City in Summer

为了加强生态园林城市建设,采用重量差值法、估算法、形态观察法,定量测定悬铃木、国槐、紫叶李、大叶黄杨、银杏、海棠、樱花、女贞等8种青州常见行道树植物的单位表面积滞尘能力。结果表明:同一种植物在不同环境条件下的单位面积滞尘量各不相同,甚至某些树种差异较大。从总体滞尘量分析得出,海岱路单位叶面积滞尘量最大,范公亭路单位叶面积滞尘量次之,云门山路单位叶面积滞尘量最小。相同环境下不同树种的单位叶面积滞尘能力差异明显。

In order to strengthen the construction of ecological garden city,the weight difference method,estimation method and morphological observation method were used to quantitatively determine the dust retention capacity per unit surface area of 8 common street trees in Qingzhou,such as Platanus,Sophora japonica,purple leaf plum,Euonymus japonicus,ginkgo,Begonia,cherry blossom and Ligustrum lucidum.The results show that the amount of dust retention per unit area of the same plant is different under different environmental conditions,and even some tree species are quite different.According to the analysis of the total dust retention,the dust retention per unit leaf area of Haidai road is the largest,the dust retention per unit leaf area of fangongting road is the second,and the dust retention per unit leaf area of Yunmen mountain road is the smallest.Under the same environment,the dust retention capacity of different tree species per unit leaf area was significantly different.
