| 中文摘要: |
| 采用走航巡测模式对2020年长江重庆—武汉段水质状况开展调查分析，并对192个巡测点位38项自动监测参数进行统计、评价、分析。结果表明：长江重庆—武汉段水质良好，全部达到或优于Ⅲ类水标准，各参数测定值水平整体不高；部分点位水质参数存在明显测定峰值，在一定程度上反映〖JP2〗周边水域受到潜在污染影响；城市江段、产业园区、港口码头、航运频繁水域污染物测定值相对增高，仍须将聚集性区域作为污染防控重点，〖JP〗加大减排力度，降低长江水污染潜在风险。 |
| 英文摘要: |
| The water quality of Chongqing-Wuhan section of the Yangtze River in 2020 was investigated and analyzed by using cruise monitoring mode, and 38 automatic monitoring parameters in 192 monitoring sites were statistically analyzed and evaluated. The conclusion was that the water quality in Chongqing-Wuhan section of the Yangtze River was good， which all met or exceeded class Ⅲ water quality standards, the concentration of each parameter was not high. The water quality parameters at some sites had obvious peak value，which reflected the impact of potential pollution on surrounding waters to some extent. The concentrations of pollutants in urban river sections，industrial parks，ports, docks and shipping busy waters were relatively high. It was necessary to focus on pollution prevention and control in large urban river sections and other concentrated areas, increase emission reduction efforts，and reduce potential risks of water pollution in the Yangtze River. |
