摘要
以香港后海湾河流水质管制区为研究对象,地表水环境质量标准(GB3838-2002)IV类为目标水质,单因子评价结果显示该处河流水质超标率最高和最低的分别为总磷(63.1%)和化学需氧量(21.4%)。基于水质评价结果筛选部分特征样点,联合PCA/FA法和APCS-MLR受体模型得到4种不同污染来源及其贡献率,可为流域水质管理提供参考。
By taking the Hong Kong Deep Bay River water quality control zone as the research object and the surface water environmental quality standard IV as the target water quality,the single-factor evaluation results show that the highest and lowest rates of river water quality exceeding the standard are total phosphorus (63.1%) and chemical oxygen demand (21.4%),respectively.Based on the results of water quality evaluation,some characteristic samples were selected,and the PCA/FA method and APCS-MLR receptor model were combined to obtain four different pollution sources and their contribution rates,which can provide a reference for water quality management in the basin.
