几种我国北方绿化树种滞尘能力的研究

目的]随着城市环境污染问题的日益严重,树种的滞尘能力成为城市绿化树种选择的一个因子。方法]对中国北方10种主要绿化树种的滞尘能力进行了研究。结果]不同树种间滞尘能力存在很大差异,阔叶乔木树种中白玉兰、槐树的滞尘能力强,毛白杨和白蜡的滞尘能力弱;阔叶灌木树种中水木旬子、金银木和紫叶小檗滞尘能力强,连翘和女贞的滞尘能力弱。结论]在北方城市绿化树种的选择上,应优先考虑乔木树种白玉兰、槐树,灌木树种水木旬子、金银木和紫叶小檗。

Study on Dust Catching Property of Major Green Tree Species in Northern China

Objective] Dust catching property was a factor which should be considered in the choice of the green tree species when the environmental pollution of the city was becoming serious.Method] Dust catching properties of ten plant species were studied and analyzed in Northern China.Result] There were obvious differences among the plants tested.Magnolia denudate,Sophora japonica,Contoneaster multiflorus,Lonicera maackii and Berberis thunbergii var.atropurpurea were proved effectively in dust catching whereas Populus tomentosa,Fraxinus chinensis,Forsythia suspense and Ligustrum lucidum were not adaptive.Conclusion] Magnolia denudate,Sophora japonica,Contoneaster multiflorus,Lonicera maackii and Berberis thunbergii var.atropurpurea should be given prior consideration in the choice of the green tree species in Northern China.
