The government work report puts forward: We must fight for the defense of blue sky, clear water, and pure land, and achieve the phased goals of pollution prevention and control.

The State Council clearly requires the launch of the "blue sky, clear water, and pure land" three major defense wars. The Ministry of Water Resources has performed its duties and resolutely fights the clear water defense battle.

The first is to strengthen the ecological flow management of rivers and lakes. The "Letter on the First Batch of Key Rivers and Lakes' Ecological Flow Guarantee Goals" was issued, and 41 key rivers and lakes' ecological flow guarantee goals were determined, including the mainstream of the Yangtze River, the mainstream of the Yellow River, the mainstream of the Huai River, and the Taihu Lake. Issued the "Guiding Opinions of the Ministry of Water Resources on Doing a Good Job in the Determination and Guarantee of the Ecological Flow of Rivers and Lakes" to provide a policy basis for strengthening the protection of the ecological flow of rivers and lakes across the country, and make arrangements and deployments.

The second is to implement water ecological protection and restoration. In-depth development of groundwater overexploitation control in North China, and the "Action Plan for Comprehensive Control of Groundwater Overexploitation in North China" was issued. In 2019, the ecological replenishment of groundwater in Hebei was 3.49 billion cubic meters, which significantly improved the water ecology. The implementation of unified water regulation, water and sand regulation, and ecological regulation of the Yellow River has achieved continuous flow of the Yellow River for 20 consecutive years, and unified water regulation of the Heihe River Basin has been carried out. Dongjuyanhai has not dried up for 15 consecutive years, and the ecological environment of the tail has been significantly improved. Vigorously promote water diversion from the Yangtze River to Tai, Niulan River — Dianchi Lake and ecological water replenishment for Baiyangdian Lake, Dongjuyanhai Lake and Taitema Lake.

The third is to promote the protection and management of drinking water sources. Completed the 2018 annual assessment of the construction of national important drinking water source safety guarantees. Organize and strengthen the tracking and analysis of important drinking water sources across the country, check abnormal data in a timely manner, and actively promote problem solving.

Fourth is the deployment and launching of a nationwide special action to "clean up the four chaos" of rivers and lakes, and has achieved remarkable results. In July 2018, the Ministry of Water Resources concentrated on rectifying and damaging prominent problems such as indiscriminate occupation, indiscriminate mining, indiscriminate piles, and disorganized construction of rivers and lakes. As of the end of December 2019, 137,000 "four chaos" problems have been cleaned and rectified across the country. The appearance of rivers and lakes has been significantly improved, the flood storage capacity of rivers and lakes has been improved, the water quality of rivers and lakes has gradually improved, and the atmosphere of the whole society to protect rivers and lakes in accordance with the law Gradually formed.

Fifth, actively promote the river chief system and the lake chief system "famous" and "realistic". The organization system of river chiefs across the country has been improved. All 31 provinces have established party-government chief river chiefs, and 320,000 river chiefs at the provincial, city, county, and township levels have been identified, and village-level river chiefs (including river inspectors, river guards) River members) 930,000 people, realizing full coverage of river and lake management and protection responsibilities; issued the "Guiding Opinions on Further Strengthening the Duty and Duty of Long and Long Lakes", conducted unannounced visits and inspections on 6,677 rivers and 1,612 lakes across the country in 2019. Special inspections were carried out in key areas such as the mainstream of the Yellow River, along the Grand Canal, and groundwater overexploitation areas in North China, and urged local governments to rectify and hold accountable for the problems discovered; breakthroughs were made in the management of chaotic conditions in rivers and lakes; The special action and the special action for the cleanup and remediation of solid waste in the Yangtze River Economic Belt have been carried out in the Yellow River basin to "hand in hand to clear the chaos and protect the mother river", and solve a large number of rivers and lakes. The state of surface water quality throughout the country in 2019 shows that among the 1940 national surface water assessment sections, sections with good water quality (Class I to III) accounted for 74.9%, a year-on-year increase of 3.9%; the proportion of sections inferior to Class V was 3.4%, a year-on-year decrease 3.3 percentage points. The ecological environment of rivers and lakes is showing a positive trend.

In the next step, the Ministry of Water Resources will focus on the water resources management goals of rational water distribution, management of water use, and systematic water management, accelerate the promotion of water distribution in river basins, strengthen ecological flow management, promote the determination of groundwater control indicators, and strictly use water Manage, promote over-extraction of groundwater in key areas, implement ecological replenishment of rivers and lakes in North China, and protect drinking water sources; further promote the normalization and standardization of "clearing the four chaos", and continue to urge localities to further refine the implementation of the rivers and lakes. Responsibilities, improve the organizational system of the river chief and the lake chief, and accelerate the realization of the "famous" and "real" river chief system; at the same time cooperate with the Ministry of Ecology and Environment to do a good job in water pollution prevention and control work, in order to improve the clean water Contribute to the defense war.
