厦门植物园空气负离子与 PM2．5浓度分布特征
为了探讨厦门植物园空气负离子浓度和PM2．5浓度在时间和空间上的分布特征，选取了厦门植物园15个观测点及园外1个对照点，在一年四季早、中、晚对他们进行现场实测并进行了分析，结果显示：四季植物园内空气负离子浓度均高于对照点；空气负离子浓度不同季节排序为夏季＞秋季＞春季＞冬季；园内植被与水边、广场之间四季空气负离子浓度均有显著差异，郁闭度高的植被样点空气负离子浓度也较高，不同植物专类园之间空气负离子浓度无显著差异；PM2．5浓度不同季节排序为夏季＜冬季＜秋季＜春季。植被与水边、广场之间四季PM2．5浓度均无显著差异，不同植物专类园之间PM2．5浓度无显著差异。...

College of Horticulture and Forestry, Huazhong Agricultural University, Wuhan 430070, China; 2. Xiamen Municipal Botanical Garden in Fujian Province, Xiamen 361003, China） Micro-environment field measurements were conducted to explore the temporal and spatial distributive characteris -tics of negative air ions （NAI） and PM2.5 concentration in Xiamen Botanical Garden in spring , summer, autumn and winter.Fifteen observation points in the botanical garden and a control observation point outside the botanical garden were set .The results were as follows：the NAI concentration at 5 points of the botanical garden was all higher than that at the control point in the four seasons ;the NAI concentration in different seasons showed the order of summer 〉autumn 〉spring 〉winter;there were significant differences in NAI concentration in the four seasons among different land types , such as |
