厦门市常见园林树种滞尘效应及生态特性研究

连续2年以厦门市区腊肠树、樟树和菩提树3种园林树种为试材。研究比较了滞尘量的差异及其生态特性。结果表明:不同园林树种滞尘能力差异显著(P〈0.05)。滞尘量基本表现为腊肠树〉樟树〉菩提树,腊肠树的滞尘量是菩提树的2倍左右;对叶面尘牲径分析表明,叶面尘中滞留的颗粒物中大多数是TSP(悬浮颗粒物),同时不同园林树种对PM10和PM2.5均有一定量的吸收,降尘物中PM2.5、PM10和TSP相对含量均以腊肠树最高,樟树和善提树较低,其中3种植物TSP差异并不显著(P〉0.05);不同树种降尘粒径主要分布在2.5—100μm,叶面降尘中颗粒物粒径集中分布在100μm以下(占99%以上)。降尘物主要为在...

Summary:连续2年以厦门市区腊肠树、樟树和菩提树3种园林树种为试材。研究比较了滞尘量的差异及其生态特性。结果表明:不同园林树种滞尘能力差异显著(P〈0.05)。滞尘量基本表现为腊肠树〉樟树〉菩提树,腊肠树的滞尘量是菩提树的2倍左右;对叶面尘牲径分析表明,叶面尘中滞留的颗粒物中大多数是TSP(悬浮颗粒物),同时不同园林树种对PM10和PM2.5均有一定量的吸收,降尘物中PM2.5、PM10和TSP相对含量均以腊肠树最高,樟树和善提树较低,其中3种植物TSP差异并不显著(P〉0.05);不同树种降尘粒径主要分布在2.5—100μm,叶面降尘中颗粒物粒径集中分布在100μm以下(占99%以上)。降尘物主要为在大气中经一定距离深移的TSP;叶绿素a和叶绿素b赶含量呈现出一致的变化规律,依次表现腊肠树〉樟树〉菩提树,可溶性蛋白依次表现腊肠树〉樟树〉菩提树,可溶性糖表现为腊肠树〉菩提树〉樟树,且三者之间差异均显著(P〈0.05);不同园林树种比叶重(x)与叶片滞尘能力(y)之间的幂函数关系最佳(P〈0.001),即比叶重较大的植物滞尘能力则较大。相关性分析表明:厦门市不同园林树种滞尘量与叶片生态特性具有较强的相关性,其中叶绿素的影响较大。

Taken three green plants (Cassia futula, Camphors officinarum and Ficus religiosaauche) as tested materials in two yeats, the effect of different environmental conditions on their dust catching quantity difference and ecological characteristics were studied. The results showed that the dust retention capacity of these green plants had significant difference (P 〈 0.05 ), and the average unit area dust catching quantity was in order of Cassia futula 〉 Camphors officinature 〉 Ficus religiosaauche, and Cassia fistula was two times of Ficus religiosaauche. The analysis on the surface of dust particle size indicated that foliar dust retention of particles in most was TSP, while PM10 and PM2.5 had a certain amount of adsorption. The d
