| 摘 要： | 为研究城市绿地对空气负离子的影响,在南昌市选择有典型特征的城市绿地,对其在不同环境状况下的空气正、负离子浓度进行监测.结果表明:1)城市绿地能有效的提高空气负离子数量;2)乔、灌、草3种不同类型的绿地中,乔木林片对提高空气负离子浓度和改善空气质量的作用最为显著;3)在城市环境下,不同林分结构类型的乔木片林对空气负离子水平以及空气质量评价指数的影响差异不显著;4)天气条件对绿地的空气负离子水平存在显著的影响;5)喷泉对空气负离子有显著的影响.

| Abstract: | The influence of urban green land on air negative ions is studied.The monitoring of the concentration of positive and negative ions of urban green land indicates:1) Urban green land can effectively increase the amount of air negative ions;2) Among arbor,bushes and grass,arbor plays the most vital role in raising the concentration of air negative ions and C_I(air clean index);3) In the city ecology environment,the influence of various arbors from different stand structure on air negative ions and C_I is insignificant;4) Weather influences significantly the concentration of air negative ions;5) Fountain has great impact on air negative ions concentration. |
