摘要
随着我国经济的迅速发展和国民生产总值的不断攀升，各方面严重的环境问题不断出现。综合来看，目前我国水污染问题是当前最亟待解决的环境问题，严重威胁着我国水资源与水环境的安全，经济发展离不开良好的水环境，人民生活也离不开良好的水资源环境。为改善水环境的质量，加强水环境管理和控制和消除水污染问题迫在眉睫，因此众多学者通过广泛深入的研究，促进了水环境研究的发展。将主成分分析法和聚类分析法等统计分析方法应用到我国水污染排放物分布的研究中，主要运用主成分分析思想，结合聚类分析步骤，建立主成分 *51今日免费论文网|www.51jrft.com +Q: ￥351916072$ 
分析和聚类分析复合模型，消除单一类型分析的缺陷不足，对取自中国统计年鉴获取的数据进行分析，从总体上进行水污染排放分布的研究。依据各省市地区水污染排放物的分布特征，对各地区水污染情况针对性分析，以研究结果为科学依据对水污染治理提出可行性建议，以加强防控并制定相关法律法规。
STUDY ON WATER POLLUTION DISTRIBUTION BASED ON PRINCIPAL COMPONENT ANALYSIS AND CLUSTER ANALYSIS
ABSTRACT
With the rapid development of Chinas economy and the continuous rise of the gross national product, serious environmental problems in all aspects continue to appear. Generally speaking, water pollution in China is the most urgent environmental problem to be solved at present, which seriously threatens the safety of water resources and water environment in China. Good water environment is indispensable for economic development and peoples life. In order to improve the quality of water environment, strengthen the management and control of water environment and eliminate water pollution, it is urgent. Therefore, many scholars promote the development of water environment research through extensive and indepth research. The statistical analysis methods, such as principal component analysis and cluster analysis, are applied to the study of the distribution of water pollution emissions in China. The principal component analysis and cluster analysis are mainly used to establish a composite model of principal component analysis and cluster analysis, combining with the steps of cluster analysis, so as to eliminate the defects of single type analysis. The data obtained from China Statistical Yearbook are analyzed, and the water is generally carried out Study on the distribution of pollution emission. According to the distribution characteristics of water pollution emissions in all provinces and cities, the paper analyzes the water pollution situation in each region, and puts forward feasible suggestions for water pollution control based on the research results, so as to strengthen prevention and control and formulate relevant laws and regulations.
