云栖竹径公园空气负离子生态效益评价

摘要

以杭州市云栖竹径公园典型植物群落毛竹纯林、常绿阔叶林及毛竹、枫香混交林为研究对象，研究3种不同植物群落空气负离子变化及其与气象因子之间的关系。研究结果表明，不同植物群落空气负离子浓度大小排序为毛竹林＞毛竹+枫香混交林＞常绿阔叶林，毛竹纯林具有更加强的环境气候调节效应，在改善城市气候方面发挥着重要的作用。%　　Taking the typical plant communities of bamboo forest, evergreen broad-leaved forest, and bamboo and Liquidamba formosana forest as an example, this paper studied the change of air negative ions and its relation with environmental factors. The result showed that the order of air negative ions concentration of different plant communities was bamboo forest>bamboo and Liquidamba formosana forest>evergreen broad-leaved forest, further more bamboo forest showed strong regulating efficiency of environment in order to play an important role on improving urban environment quality.
