厦门植物园空气负离子与 PM2.5浓度分布特征
Distributive Characteristics of Negative Air Ions and PM2.5 Concentration in Xiamen Botanical Garden
摘要
Abstract
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 the vegetation , the waterside and the square , and the NAI concentration at the vegetation point with high canopy density was also higher , but there was no significant difference in NAI concentration among various special plant zones in the botanical garden ;the PM2.5 concentration in different seasons changed in the order of summer <winter <autumn <spring;there were no significant differences in PM 2.5 concentration in the four seasons a-mong different land types and among various special plant zones .关键词
