摘要
应用因子分析模型针对不同的污染区逐一分析其污染源,应用spss软件确定主要影响因子,给各污染源确定名称.结果表明,低污染区受人类活动影响较小,在中污染区和高污染区以混合污染源为主,其中主干道路区和工业区属于较重污染,交通污染和冶炼厂、化工厂工业废气影响较为突出,建议采取有效措施减少其对土壤重金属污染.
The factor analysis model for different levels of pollution to analyze its sources is applied. It adopts spss software to analyze the main influence factors. The causes of pollution is analyzed, and the names of the source of pollution is determined. The results show that the low contaminated areas are less affected by human activities, and high pollution is full of mixed contamination. Trunk roads and industrial areas are heavier pollution. They are affected by traffic pollution and smelters, chemical industrial emissions. It is recommended that take effective measures to reduce its heavy metal pollution.
