摘要：用多重比较法分析比较豫北地区不同功能区杨树、悬铃木、国槐、白蜡4种树木叶片铅含量与叶面尘中铅含量有无显著性差异,拟合4种叶片铅含量与大气铅浓度以及叶面尘中铅含量之间一元生物检测的数学模型,利用多元回归分析法建立三者之间的联系。结果表明,一元生物监测数学模型均显示,不同地区的4种树木的叶片与叶面降尘中含铅量、叶片与大气中铅含量均呈显著相关(悬铃木、白蜡)或极显著相关(杨树、国槐)。二元生物监测数学模型显示,杨树和国槐叶片的铅含量与叶面尘的污染元素铅含量以及大气污染物铅浓度均呈极显著相关(R^2=0. 779 2、0. 771 3),悬铃木、白蜡叶片的铅含量与叶面尘的污染元素铅含量以及大气污染物铅浓度均呈显著相关(R^2=0. 736 8、0. 733 3)。
The significant difference about lead content betwteen Populous canadensis,Platanus hispanica,Sophora japonica and Fraxinus chinensis blades and foliar dust in different functional,areas in Yubei area were studied with multiple comparisons.Fitting monadic mathematic model of blades lead content and.atmospheric pollutants lead concentration and foliar dust pollution elements lead content,the multivariate regressions analysis method was used to establish the relations among the atmospheric pollutants lead concentrations and the lead content of blades and foliar dust.The monadic biological monitoring mathematic models showed that lead content in blades and at- mospheric,in foliar dust and atmospheric in different areas were significant correlation (Platanus hispanica and Fraxinus chinensis)or extremely significant correlation (Populus canadensis and Sophora japonica).The binary biological monitoring mathematic models showed that the atmospheric pollutants lead concentration and the lead content of blades and foliar dust of Populous canadensis and Sophora japonica were extremely significant correlation (R^2=0.7792,0.7713),the atmospheric pollutants lead concentration and the lead content of blades and foliar dust of Platanus hispanica and Fraxinus chinensis were significant correlation (R^2=0.7368,0.7333).
