基于水环境分析的南方典型中小城市类型划分及水污染驱动力研究

根据我国南方中小城市水环境污染的主要来源，选取工业废水排放量等10项指标，建立城市类型划分及其影响因素的评价指标体系，并以江苏、浙江、湖北和安徽的16个典型中小城市进行了研究.结合SPSS11.0聚类分析结果，依据经济发展指标值与综合污染排放指标值划分了城市类型，运用主成分分析法研究了水环境污染的驱动力.结果表明，南方16个典型中小城市可划分为经济发展好、水环境污染轻和经济发展一般、水环境污染重两类Ⅳ亚类；水环境污染的影响因素依次为工业用水污染、农业面源污染和城镇生活污染；影响第Ⅰ亚类、第Ⅱ亚类以及Ⅳ亚类和第Ⅲ亚类城市的主要因素分别为工业用水污染、城镇生活污染和农业面源污染.

Study on the Types and Water Pollution Driving Forces of the Typical and Medium-Small-Sized Cities in the Southern China Based on the Analysis of Water Environment

According to the major pollution sources of urban water environment,10 indexes such as industrial sewage quantity were closen to establish evaluation indexes system about the types and influencing factors of the typical and medium-small-sized cities in the southern China. Case studies of 16 typical and medium-small-sized cities were taken in Jiangsu,Zhejiang,Hubei and Anhui provinces. Combined with SPSS 11.0 cluster analysis results,city types were divided in reference to the values of water resources compr...
