| 摘 要： | 采用模糊数学方法对大沽河干流河水水质进行综合评价。选定西巨家等9个监测断面,确定高锰酸钾指数等7个评价因子,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,得到各监测断面的综合水质状况。进一步分析发现,早朝、江家庄监测断面综合水质较差。与实际结果进行比较可知,采用模糊数学方法评价水质状况是一种较为恰当的方法。

| Abstract: | In this paper,fuzzy mathematical method was used to evaluate Dagu River water quality.Nine Detection of cross-sections(Such as Xijujia,etc.) with seven evaluation factors(such as potassium permanganate index etc.) were selected to establish an evaluation factor matrix.The comprehensive water quality of each section was obtained by fuzzy computing with their calculate weight.The analysis revealed that the water qualities were bad in Zaochao,JiangJiaZhuang monitoring sections.Compared with the actual results ... |
