基于因子分析法的交通污染源分析研究

随着城镇化、工业化的发展,交通污染问题愈发严重,重金属在表层土壤的污染程度也愈演愈烈,已经严重威胁到人类的生产和生活。因此研究交通活动影响下城市的地质环境显得尤为重要。本文基于环境单元数据,运用地统计学软件计算区域土壤重金属的半变异函数,研究区域土壤重金属含量的空间结构特征。并利用多个实测变量之间的相互关系,运用数学变换,将多个变量转变为少数几个线性不相关的综合指标,用较少的有代表性的因子来说明众多变量所提取的主要信息,从而有效地确定交通污染源。

Research on Traffic Pollution Sources Based on Factor Analysis

With the development of urbanization and industrialization,traffic pollution has become more serious,pollution levels of heavy metal in the soil surface has intensified,which has a serious threat to human life and production,so studying urban geological environment under the influence of the traffic activities is particularly important.This paper,based on the environment unit data,studies space structure features of regional soil heavy metal content,applying geostatistics software to calculate semivariable function of regional soil heavy metal.And by using relationships among multiple measured variables,applying mathematics transform,it takes the multiple variables into a few linear uncorrelated comprehensive indexes,explains main information numerous variables extract,and then determines the traffic pollution sources effectively.
