摘　　要：对长株潭生态绿心区内不同类型林分和不同植物配置模式下的PM_(2.5)和O_(3)质量浓度进行了测定,比较了不同类型林分之间PM_(2.5)和O_(3)质量浓度的差异性,以期筛选出对复合污染物具有较强抗性的树种和植物配置模式。结果表明:PM_(2.5)质量浓度的日变化为“单峰单谷”型,而O_(3)质量浓度的日变化则呈“单峰”型。不同类型林分的PM_(2.5)质量浓度呈现出混交林高于纯林、针叶林高于阔叶林的变化趋势,其中阔叶混交林的最低;不同类型林分的O_(3)质量浓度则表现出落叶阔叶纯林的最高,其次是针叶混交林和阔叶混交林。不同类型林分的PM_(2.5)与O_(3)质量浓度主要呈负相关关系,平均相关系数为-0.247(P<0.05),这表明各类型林分的PM_(2.5)质量浓度和O_(3)质量浓度之间呈相反的变化趋势。不同植物配置模式的PM_(2.5)和O_(3)质量浓度的交互效应强度具有显著差异(P<0.05)。基于上述分析,筛选出11种对PM_(2.5)与O_(3)复合污染具有较强综合抗性能力的植物配置模式,分别为:杉木+香樟(5∶5)、毛竹+杉木+香樟(2∶4∶4)、马尾松+杉木(7∶3)、杉木、石栎、杜英、白花泡桐、青冈+枫香树(6∶4)、香樟+盐肤木(7∶3)、香樟、石楠。这些树种和配置模式的PM_(2.5)与O_(3)质量浓度之间的交互效应较强,因此也可作为湖南省PM_(2.5)与O_(3)复合污染协同控制的森林植物选择及森林优化配置的优选树种和类型。The concentrations of PM_(2.5) and O_(3) were measured in different forest types and plant configurations in the green heart area of Changsha-Zhuzhou-Xiangtan.The concentrations of PM_(2.5) and O_(3) were compared in different forest types.The results indicated that:The daily variation of PM_(2.5) concentration followed a“single peak and single valley”pattern,while the daily variation of O_(3) concentration showed a“single peak”pattern.In terms of PM_(2.5) concentration,mixed forests tended to have higher levels than pure forests,coniferous forests higher than broad-leaved forests,with broad-leaved mixed forests being the lowest.Regarding O_(3) concentration,the highest levels were observed in deciduous broad-leaved pure forests,followed by coniferous mixed forests and broad-leaved mixed forests.There was a negative correlation between PM_(2.5) and O_(3) concentrations in different forest types,with an average correlation coefficient of-0.247(P<0.05),indicating that there was an opposite trend in PM_(2.5) and O_(3) concentrations among different forest types.There were significant differences(P<0.05)in the intensity of PM_(2.5) and O_(3) concentration effects among different plant configurations.Eleven plant species and configuration types with strong comprehensive resistance to PM_(2.5) and O_(3) combined pollution were selected,including Cunninghamia lanceolata+Cinnamomum camphora(5/5),Phyllostachys edulis+Cunninghamia lanceolata+Cinn a momumc a mphor a(2/4/4),Pinus mas soni a n a+Cunningha mi a la mold t a(7/3),Cuuningh h mia la mold t a,Lithocarpus glabra,Elaeocarpus decipiens,Paulownia fortune,Quercus glaaca+Liquidambar formosaaa(6/4),Cinnamomumcamphora+Rhus chinensis(7/3),Cinnamomum camphorr,Photinii serratifolii.These tree species and configuration modes exhibited strong interaction effects between PMz 5 and O_(3) concentrations and could be used as forest plant selection and forest optimization configuration for the synergistic control of PMz 5 and O_(3) compound pollution in Hunan Province.
