摘要
该文采用主成分分析法对沙河水质进行分析评价,选取具有代表性的6个断面和溶解氧、高锰酸盐指数、化学需氧量、五日生化需氧量、氨氮、氟化物、锰7个水质指标进行了分析计算。并以石佛口断面为研究重点,研究分析断面水体的主要污染物。结果表明,主成分分析方法在指标权重选取方面具有减少主观误差,操作简单等优越性。
In this paper,principal component analysis is used to analyze and evaluate the water quality of Shahe.6 representative sections and dissolved oxygen,permanganate index,chemical oxygen demand,five day biochemical oxygen demand,ammonia nitrogen,fluoride and manganese 7 water quality indicators are selected for analysis and evaluation.Taking the stone section as the research focus,research the main pollutants analysis section of water.The results show that the principal component analysis method has the advantages of reducing subjective error and simple operation in the selection of index weight.
