基于主成分分析法的黑龙江省人居环境污染因子评价应用研究

Principal Component Analysis Study for the Evaluation of Pollution Factors of Residential Enviroment in Heilongjiang Province

黑龙江作为全国重要的农业和畜牧业大省,人居环境污染必然受到相关影响。然而当前很少有人对该问题量化研究,进而提供对策。选取了化肥农药等7个污染因子,利用SPSS软件对相关数据进行主成分分析,构建了黑龙江省人居环境污染因子评价模型,评价结果显示:化肥农药、生活垃圾、地膜使用为黑龙江省人居环境影响最靠前的三个污染因子,与黑龙江省省情实际相符,据此提出应用对策,以期为黑龙江省人居环境建设提供优化建议。

As an important agricultural and animal husbandry province,residential environment pollution was bound to be negatively affected.Few people performed quantitative research to provide countermeasures to this problem.7 pollution factors,such as chemical fertilizers and pesticides were selected to conduct principal component analysis by SPSS software.Following the analysis,an evaluation model of the environmental pollution factors in Heilongjiang province was created.The results showed that chemical fertilizers,domestic waste and mulching film were three most predominant factors of pollution to the environment in Heilongjiang province,which corresponded to the actual situations of Heilongjiang province.Optimal suggestions were provided for environmental protection and preservation in Heilongjiang province.
