Xinhua news agency, Beijing, May 7 (reporter Gao Jing) the Ministry of ecology and environment announced the ranking of water environment quality of national surface water assessment sections in cities at prefecture level and above for the first time on July 7.

From the first quarter of this year, the national surface water assessment section of cities at prefecture level and above will be ranked in terms of water environment quality status and change situation, according to the relevant person in charge of the Ministry of ecological environment. The list of cities covers all cities at prefecture level and above with national surface water assessment sections. 2050 national surface water assessment sections (including 1940 national surface water assessment sections and 110 sea entry control sections) participate in the ranking, which are mainly distributed in seven river basins including Yangtze River, Yellow River, Pearl River, Songhua River, Huaihe River, Haihe River and Liaohe River, as well as Northwest rivers and southwest rivers The main rivers and key lakes and reservoirs in Zhuhe and Zhejiang Fujian areas. The ranking does not involve urban groundwater, black odorous water body, and small rivers, lakes or reservoirs without national surface water assessment section.

"The ranking can objectively reflect the effectiveness and efforts of local governments in water pollution prevention and control, further enhance the enthusiasm of local governments in water pollution prevention and control work, and promote the steady improvement of national water environment quality." The person in charge said. The Ministry of ecological environment organizes the unified implementation of the separation of sampling and measurement for the assessment section, realizes the decoupling of water quality monitoring and assessment objects from the operation mechanism, ensures the independence, objectivity and impartiality of the monitoring data, realizes the quality control of the whole process and each link of water quality monitoring, comprehensively improves the data quality, and provides real and reliable data support for ranking.

In the first quarter of this year, the water environment quality of national surface water assessment sections in 30 cities, including Ya'an, Laibin and Yunfu, was relatively good, while that of Luliang, Yingkou and Xingtai was relatively poor; that of Siping, Changchun and Zhongshan was relatively good, while that of Luliang, Yingkou and Shuozhou was relatively poor.

The person in charge said that in the first quarter, the overall quality of water environment in China improved. Among the 1940 national surface water assessment sections, 74.3% of the sections with good water quality accounted for 74.3% with an increase of 8% over the same period of last year; the proportion of sections with poor grade V was 6%, with a decrease of 3.6% over the same period of last year. However, the situation of water environment reaching the standard in some areas is grim. There is a significant gap between the two goals of the proportion of excellent water body and the proportion of inferior class V water body in Shanxi, Jilin, Guangdong, Guangxi, Shaanxi and Gansu compared with the annual target. Shanxi and Liaoning have 20 inferior grade V national control sections respectively, and the number of inferior class V national control sections in each province ranks first.
