| 中文摘要: |
| 为研究某城市的水质污染情况，对某城市2022年5大主要水系17 个河流断面水质的14项指标进行取样分析，通过主成分分析法得出电导率、溶解氧、高锰酸盐指数和五日生化需氧量等为主要的污染因子；鉴于目前河流水质污染的实际情况，重点选取溶解氧、高锰酸盐指数、五日生化需氧量、总氮、总磷和氨氮等指标进行分析，并从时间和空间的维度揭示了不同水系各个断面的水质变化特征。结果显示，水质在不同季节和汛期表现出显著差异，总体趋势为秋季>；春季>；夏季>；冬季，且汛期优于非汛期；溶解氧指标的季节变化独立于整体水质的变化趋势，呈现为冬季>；春季>；秋季>；夏季，且非汛期优于汛期。 |

| In order to study the water quality pollution situation of a certain city, samples of 14 indicators of the water quality at 17 river sections of the five major water systems in the city in 2022 were taken and analyzed. Through the principal component analysis method, it was concluded that conductivity, dissolved oxygen, permanganate index, and biochemical oxygen demand for five days, etc. , were the main pollution factors. In view of the actual situation of current river water quality pollution, key indicators such as dissolved oxygen, permanganate index, biochemical oxygen demand for five days, total nitrogen, total phosphorus, |
