| 摘 要： | 对浙江省临安市6种植物群落距地面1.5 m处的空气负离子浓度进行了研究。结果表明：不同群落模式的空气负离子浓度差异显著；除草坪外，各群落的负离子浓度显著高于相应的空地；6种参试群落模式的空气负离子浓度相对值由高到低依次为马尾松Pinus massoniana群落，无患子Sapindus mukorossi-广玉兰Magnolia grandiflora混交群落，雷竹Phyllostchys praecox群落，杉木Cunninghamia lanceolata群落，紫薇Lagerstroemia indica群落，草坪；就植物群落负离子昼间变化来看，从7 : 00到19 : 00呈双峰状，分别在9 : 00 － 10 : 00和15 : 00 － 16 : 00各出现1个峰值；对空气负离子与其他气象因子的相关分析显示，空气负离子与相对湿度极显著正相关（P＜0.01）、与气温显著负相关（P＜0.05）、与太阳辐射强度变化趋势相反。空气负离子浓度与户外紫外线强度呈显著正相关（P＜0.05）。图2表3参15

| Abstract: | A comparison of 1.5 m above ground aero-anion and positive air ion concentration for six plant communities,Pinus massoniana,Sapindus mukorossi,Magnolia grandiflora,Phyllostachys praecox,Cunninghamia lanceolata,Lagerstroemia indica,and turf grass,was conducted using a correlation analysis with relative humidity,temperature,solar radiation intensity,and ultraviolet radiation intensity. Results showed that compared to a corresponding open space,the aero-anion effect was better in each plant community,and their... |
