青山湖不同植物群落空气负离子效应评价

Study on Air Negative Ions Ecological Efficacy of Different Plant Community in Qingshan Lake

以临安市青山湖湿地公园典型植物群落常绿阔叶林、香樟林、池杉林及人工林为研究对象,研究4种不同植物群落空气负离子效应及其空气清洁度的比较。研究结果表明,不同植物群落空气负离子浓度大小排序为常绿阔叶林>人工林>香樟林>池杉林,常绿阔叶林空气负离子浓度最高,环境调节功能最强,其对改善湿地公园环境质量发挥着重要的作用。

Taking the typical plant communities of evergreen broad leaved forest and Cinnamomum camphora, Taxodium ascendens and artificial forest as an example, this paper studied the ecological efficacy of air negative ions and the compare of air cleanness among four different plant communities. The result showed that the order of air negative ions concentration of different plant communities was evergreen broad leaved forest 〉 artificial forest 〉 Cinnamomum camphora ~ Taxodium ascendens, further more evergreen broad leaved forest had the highest air negative ions concentration and strong regulating efficiency of environment and would play an important role to improve the environmental quality of urban wet land park.
