摘要
本文基于2007年第一次全国污染源普查数据,运用主成分分析法,对南四湖流域山东省境内的28个县市区行政单元的水污染物排放水平进行了综合评价,结果显示:滕州市的污染物排放水平明显高于流域内的其他区域,济宁市中区、邹城市、菏泽市区、曹县的污染物排放水平也较高。因此这五个县市是今后南四湖流域治污的重点。
This paper applies the Principal Component Analysis Method to evaluate the water pollutant emission levels of the 28 counties of Nansi Lake basin. Results shows that pollutant emission levels of Tengzhou city are significantly higher than other areas of the basin. Jining City, Zoucheng city, Heze city, Cao county have high emission levels of pollutants, and therefore are recognized as the key areas for pollution control in Nansi Lake basin in the future. Suggestions on the entire river basin management and pollution control measures are also put forward.
