摘要:
 以湖南省武陵山区女儿寨小流域11种常见生态树种为研究对象,测定其单位叶面积对空气中PM2.5等颗粒物的滞留量,为筛选滞尘能力较强的生态树种提供依据。结果表明,不同树种单位叶面积吸附PM2.5的量各不相同,主要受其叶表微结构、枝叶密集度、叶质地、叶面倾角等因素的影响。各树种单位叶面积吸附PM2.5量大小排序为杉木(0.131 μg·cm-2)>马尾松(0.041 μg·cm-2)>青冈栎(0.032 μg·cm-2)>苦槠(0.023 μg·cm-2)>枫香(0.016 μg·cm-2)>刺槐(0.014 μg·cm-2)>木荷(0.013 μg·cm-2)>泡桐(0.007 μg·cm-2)>湿地松(0.006 μg·cm-2)=柏木(0.006 μg·cm-2)>桤木(0.005 μg·cm-2)。不同树种单位叶面积吸附TSP、PM1、PM10量的大小排序无规律。泡桐单位叶面积吸附TSP量最大,湿地松最小;马尾松单位叶面积吸附PM1量最大,柏木最小;杉木单位叶面积吸附PM10量最大,柏木最小。常绿树种单位叶面积吸附的TSP、PM1、PM10、PM2.5量远大于落叶树种。
Abstract:
 Taking 11 ecological tree species that are commonly occurring in Niuerzhai watershed in Wuling mountainous area,Hunan,as research objects,the amounts of PM2.5 and other particulates retained on the leaves of the trees studied were measured to select those with strong capabilities to retained atmospheric particulates.The results showed that the adsorption amounts of PM2.5 per unit leaf area were different among different tree species,which were mainly affected by foliage microstructure,branche and leaf density,leaf texture,and the leaf angle.The order of PM2.5 adsorption quantity per unit leaf area of the tree species studies was Cunninghamia lanceolata(0.131 μg·cm-2)>Pinus massoniana(0.041 μg·cm-2)>Cyclobalanopsis glauca(0.032 μg·cm-2)>Castanopsis sclerophylla(0.023 μg·cm-2)>Liquidambar formosana(0.016 μg·cm-2)>Robinia pseudoacacia(0.014 μg·cm-2)>Schima superba(0.013 μg·cm-2)>Paulownia(0.007 μg·cm-2)>Pinus elliottii(0.006 μg·cm-2)=Cupressus funebris(0.006 μg·cm-2)>Alnus cremastogyne(0.005 μg·cm-2).No regularities were found on the adsorption amounts of other particulates on the leaves of different tree species,such as TSP,PM1,and PM10.The TSP adsorption amount per unit leaf area of Paulownia was the largest while Pinus elliottii was the least.The PM1 adsorption amount per unit leaf area of Pinus massoniana was the largest ,Cupressus Funebris was the least.The PM10 adsorption amount per unit leaf area of Cunninghamia lanceolata was the largest,Cupressus funebris was the least.For different leaf habits,TSP,PM1,PM10 and PM2.5 amount per unit leaf area of evergreen tree species was greater than the deciduous species.
