| 摘 要： | 以灰色关联理论为基础,借助四川省18个地级市的统计数据,定量分析污水处理率与用水普及率、污水排放量、排水管道长度、城区面积、人均地区生产总值等指标的灰色关联度,深入研究影响城市污水处理的主要因素.研究表明:城市污水处理率与城市市区用水普及率的关联程度最为密切,与排水管道长度的关联程度最小.

| Abstract: | Based on the grey correlation theory, and the data of 18 main cities in Sichuan Province, this paper quantitative analyzes the grey correlation degrees between sewage treatment ratio and water-using population ratio, sewage discharge volume, drainage pipe length, urban area, per capita gross domestic product, and also explores he main factors influencing the urban sewage treatment ratio. The study finds that the urban sewage treatment ratio has the maximum correlation to the water-using population ratio, and has the minimum correlation to the drainage pipe length. |
