| 摘 要： | 通过对南宁城区、城郊绿地及农田开发区进行负离子含量的测定，找出不同植被配置类型空气负离子效应的差别。结果表明，就空气负离子而言，城郊大规模绿地的空气质量〉农田开发区〉城区；植被配置的复层结构（乔灌草）〉简单植被配置结构（乔灌、乔草、灌草）〉单一配置结构（草坪、稀乔、稀灌草）。溪流和瀑布对增加负离子浓度的作用显著。随着海拔和郁闭度的增加，空气负离子含量有上升的趋势。空气负离子含量随季节有一定的波动。 |

| Abstract: | In this paper,the concentrations of air negative ions above urban area,suburb green space,and farmland in Nanning city were measured.The results indicated that from the viewpoint of air negative ions,the air quality was in order of large scale suburb green space > farmland > urban area.Vegetation with multi-structure was the best,followed by vegetation with simple structure,and single vegetation pattern.Creek and waterfall could raise the concentration of air negative ions effectively.The concentrations of air negative ions increased with ascending altitude and canopy density,and fluctuated with season. |
| Keywords: | city vegetation arrangement air negative ions effect evaluation. |
