Since the beginning of this year, water conservancy investment has continued to make progress, and the construction of the national water network has been accelerated. According to the data of the Ministry of water resources, by the end of July, 25 major water conservancy projects had been started, 31800 water conservancy projects were under construction, and the investment scale reached 1.7 trillion yuan; The investment in water conservancy construction was 567.5 billion yuan, an increase of 71.4% over the same period last year. The construction of water conservancy facilities has been accelerated in an all-round way. Water conservancy projects have played a positive role, effectively ensuring the needs of social production and life, and providing strong support for high-quality development. Water security is a major issue concerning the long-term stability of the country. The Party Central Committee has always attached great importance to the water conservancy cause and made efforts to solve the problem of water security from a strategic height. Since the 18th National Congress of the Communist Party of China, the development of water conservancy in China has stepped to a new level and solved many problems that have long been unsolved. Over the past decade, the investment in water conservancy construction has been kept at a high level and the investment structure has been continuously optimized. Despite the impact of COVID-19 and various unexpected factors, the construction of water conservancy facilities is still progressing steadily. The "package of policies and measures to stabilize the economy" issued by the State Council takes "accelerating the promotion of a number of proven water conservancy projects" as an important measure to stabilize investment. A series of top-level designs based on the long-term and the present have laid a solid foundation for comprehensively improving the national water security guarantee capacity. The comprehensive benefits of national water network construction are constantly showing. With the construction of a number of large-scale cross basin and cross regional key water diversion projects, the ability of water network to optimize the allocation of water resources has been continuously improved. The general pattern of water resources allocation of "North-South allocation and east-west mutual assistance" has effectively alleviated the bottleneck of water bottle affecting regional social development. Since the first phase of the east middle line of the South-to-North Water Transfer Project was fully opened, more than 140 million people have been benefited. "Less scale, better water quality, better porridge and cooking". Behind the heartfelt praise of the masses, there is a real improvement in the sense of happiness and gain. China's flood control engineering system is also improving day by day. For example, the Jiangsu section of Wusong River, which was started in May this year, is a landmark project for the comprehensive treatment of the Taihu Lake Basin. Its construction will increase the drainage channels for the flood of Taihu Lake, improve the flood control and drainage capacity of the Taihu Lake Basin, and play an important role in improving the regional water resources, water environment and water ecological conditions. The regional flood control capacity of the river basin has been continuously enhanced, the hidden dangers of water disasters have been reduced, and the safety of people's lives and property has been guaranteed. A series of major water conservancy projects have truly realized the advantages and eliminated the disadvantages. Water conservancy projects are also an important guarantee for securing the rice bowls of the Chinese people. The effective irrigated area of farmland in China accounts for 54% of the total cultivated land in China, producing more than 75% of the total grain and more than 90% of the economic crops. This year's No. 1 central document of the central government proposes to increase the support and transformation of large and medium-sized irrigation areas, plan to build a batch of modern irrigation areas in areas with suitable water and soil resources, and give priority to building large and medium-sized irrigation areas into high-standard farmland. According to the requirements of the central government, the investment scale of large and medium-sized irrigation area construction and transformation projects this year will reach 38.8 billion yuan. Scientific planning and systematic implementation, large and medium-sized irrigation areas can be irrigated by drought and drained by flood, providing "source guarantee" for stable and high grain yield. Water conservancy concerns the well-being of millions of people. Vigorously building a national water network and continuously improving the governance and utilization capacity of water resources, water ecology and water environment will better benefit the Chinese people and protect the Chinese people
