摘　　要：采用模糊数学方法对太子河流域水质进行综合评价。沿程选取老官砬子、兴安、参窝坝下等8个干流断面和汤河桥、河洪桥、孟柳等6个支流断面,确定五日生化需氧量(BOD5)、化学需氧量(COD)、氨氮(NH3-N)、挥发酚(FN)等7个指标为评价因子,通过建立评价因子矩阵,计算各因子的权重及进行模糊综合运算,得出各监测断面的综合水质状况。水质模糊综合评价结果表明,太子河干流和支流各监测断面的综合水质较差,V类水质断面所占比例达85.7%。在各项评价指标中,BOD5和挥发酚所占权重较高,其次为COD和NH3-N等,这几项指标应该作为太子河流域十二.五污染减排和治理的重点。The fuzzy mathematical method was used to evaluate the water quality of the Taizi River.Eight main stream sections such as Laoguanlazi,Xingan,Senwobaxia,and six branch stream sections such as Tanghe Bridge,Hehong Bridge,Mengliu,were investigated with seven evaluation factors such as BOD5,COD,NH3-N,volatile phenol.An evaluation factor matrix was established and the comprehensive water quality of each section was obtained by fuzzy computing with a weighting calculation.Analysis results revealed that the water quality in the monitoring sections of the main and branch streams of the Taizi River was very poor since 85.7% of the total monitoring sections were Grade V water.The factors of COD and NH3-N were the main pollutants,followed by the BOD5 and volatile phenol,which should be controlled preferentially in the Twelfth Five-Year Plan for Taizi River recovery.
