对浙江省临安市6种植物群落距地面1.5m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 masoniana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).

A comparison of 1.5m above ground aero-anion and positive air ion concentration for six plant communities,Pinus massoniana,Sapindus mukorossi,Magnolia grandiflora,Phyllostachys praecox,Cun-ninghamia 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 individual aero-anion concentration Was in the order of P.massoniana>S.mukorossi and M.grandiflora>P.praecox>C.lanceolata>L.indica>turf grass.According to the diurnal variation curve between 7:00 and 19:00,the aero-anion concentration tended to double peak from 9:00-10:00 and15:00-16:00.A correlation analysis showed a significant(P<0.01)positive correlation(r=0.702)be-tween aero-anion concentration and relative humidity,a significant(P<0.05)negative correlation(r=-0.637)between aero-anion concentration and temperature,a negative correlation(r=-0.191)between aeroanion concentration and solar radiation intensity,and a significant(P<0.05)positive correlation(r=0.580)between aero-anion concentration and ultraviolet radiation intensity(UVB).
