摘要: 通过在宁波镇海区的三条生态隔离林带（海天生态隔离林带、镇骆生态隔离林带与雄镇生态隔离林带）中采集植物叶片样本，分析叶片中硫、氯、氟、锌和铁五个污染物含量，定量研究生态隔离林中的植物对污染物的吸收状况，为目前城市生态隔离林带生态效益的相关评价工作提供科学依据以及城市生态隔离林带建设树种选择提供参考.结果表明，不同林带间植物叶片污染物的含量具有显著差异性，林带距离化工区越近污染物的含量越高，表现出较高的净化大气的生态效益.海天生态林带镇骆生态林带雄镇生态林带.利用DPS软件对数据进行分析，八种植物中，综合生态效益在净化大气方面从高到低依次为杨树＞池杉＞珊瑚＞木槿＞女贞＞香樟＞杜英＞桂花.Abstract: Based on the quantitive analysis of five pollutant contents in the leaf samples which were collected from the three ecological forests in Zhenhai district, Ningbo,Zhejiang province, this research is expected to provide experimental data for the evaluation on the effective of ecological forest and species chosen. The results showed that, as the distance between the ecological forest and the industry areas become shorter, the content of pollutants in plants and the ecological benefits of purifying the air become higher; that is, Haitian ecological forest belt Zhenluo ecological forest beltXiongzhen ecological forest belt. The ecological benefits of the eight plants are ranked by DPS. From high to low, the sequence is populus sp,Taxodium ascendens,Viburnum odoratissimum, Hibiscus syriacus, Ligustrum lucidum, Cinnamonum camphora, Elaeocarpus balansae, Osmanthus fragrans.
