太子河水质污染时空异质性分析

Analysis on Space-time Heterogeneity of Water Pollution in Taizi River

汇总1995—2009年太子河干流8个常规监测断面的监测数据,通过计算超标率和平均超标倍数确定氨氮、COD、总磷和阴离子表面活性剂为太子河干流主要污染指标,石油类、挥发酚和氟化物为特征污染指标,详细分析了主要污染指标的时间、水期、空间分布规律,为辽河流域水污染治理及编制流域规划提供技术支撑。

The data of 8 main stream cross sections of Taizi River from 1995 to 2009 was collected to calculate overweight rate and average overweight times.The conclusions were made out that NH4-N,COD,TP and anionic surfactant were main pollution indexes.Oil,volatile phenol and fluoride were feature pollution index.On the other hand,the distributions of time,period,space were analyzed to provide technical support for Liaohe basin water pollution management and compiling watershed planning.
