摘要: 基于监测数据,系统分析了某北方典型城市3种不同类型河流的水质空间分布,探讨了各水质指标之间的相关性。通过聚类分析对水质进行空间分组,结果表明:3条河流综合的水质空间相似性较为一致,均表现为上游或中上游断面平方欧氏距离较为接近,下游或中下游断面亦同。单一河流与3条河流总体的相关性分析分别得到P<0. 05和P<0. 01水平下显著相关的水质指标。极显著相关(P<0. 01)的水质指标回归分析结果表明:TN与NH3-N、COD与BOD5之间拟合效果较好,相互之间解释力较高,但TP与NO3--N、TN与NO3--N之间尽管极显著相关,但拟合结果较差,相互之间并没有较好的解释力,且即使变换其他形式的拟合方程,其效果也不佳。
