The construction of water conservancy infrastructure is related to the guarantee and safety of the people's lives. The Shandong Provincial Government Information Office held a press conference on September 13 to interpret the "14th Five-Year Plan for Water Conservancy Development in Shandong Province". According to Liu Zhonghui, director of the Provincial Water Resources Department, by 2025, Shandong Province will initially establish a water safety guarantee system with Shandong characteristics that meets the requirements of high-quality development.

The "Plan" clarified the binding indicators and expected indicators. By 2025, Shandong’s total water consumption will be controlled within 28.922 billion cubic meters. Water consumption per 10,000 yuan of GDP will be reduced by 10% compared with 2020. Water consumption for 10,000 yuan of industrial added value will be reduced by 5% compared with 2020. The effective utilization coefficient of irrigation water will be increased to 28.922 billion cubic meters. 0.651, the construction rate of a water-saving society at the county level reached 90%, the newly added reservoir capacity was 1.2 billion cubic meters, the new water supply capacity was 1 billion cubic meters, the urban reclaimed water utilization rate reached 50%, the rural tap water penetration rate reached 97.5%, and urban and rural water supply was integrated. The reduction rate reached 70%, the embankment compliance rate reached more than 77%, the existing large and medium-sized dangerous reservoirs had a completion rate of 100%, the completion rate of small and dangerous reservoirs was 100%, and the water and soil conservation rate reached more than 85%. , The proportion of surface water reaching or better than Class III water bodies completed the national decomposition task, and the basic ecological flow (water volume) of key rivers and lakes reached the standard rate of more than 90%. At the same time, during the "14th Five-Year Plan" period, Shandong Province will plan to implement the follow-up projects of the east route of the South-to-North Water Diversion, including municipal and county facilities, water supply guarantee, flood control enhancement, water ecological protection and restoration, digital water conservancy, and large and medium-sized reservoir resettlement support for a total of 1088 key water conservancy projects. The total estimated investment of the project is 385.5 billion yuan, of which 214.3 billion yuan has been invested during the "14th Five-Year Plan" period.

During the "Thirteenth Five-Year Plan" period, Shandong Province has completed a total of more than 200 billion yuan in water conservancy investment, focusing on the goal of "eradicating floods and preventing drought", and the level of water security has been significantly improved. "However, affected by natural geography and climatic conditions, severe floods and severe droughts coexist in Shandong Province, resource water shortages and engineering water shortages coexist." Sun Tao, chief engineer of the Provincial Development and Reform Commission, said frankly that flood risk is still a serious hidden danger in Shandong Province. The provincial backbone water network has not yet achieved the coverage of Shandong Province, the contradiction between water supply and demand in some areas is still prominent, and the development and utilization of water resources in some areas exceeds the carrying capacity of local resources and environment. The "14th Five-Year Plan" period is the key five years for Shandong Province to accelerate the conversion of new and old kinetic energy and promote high-quality development. There is an urgent need to further improve the optimal allocation of water resources and the ability to prevent floods and droughts.

Green water and green mountains are golden mountains and silver mountains. While emphasizing infrastructure construction, the issue of ecological protection cannot be ignored. "Focusing on the national strategy of promoting the ecological protection and high-quality development of the Yellow River Basin, the water conservancy department will build green ecological corridors in the lower reaches of the Yellow River, promote the conservation and intensive use of water resources, implement the construction of flood control projects in the lower reaches of the Yellow River, and excavate and carry forward the excellent water culture of the Yellow River. In terms of key tasks to contribute to water conservancy power." Liu Jianji, Director of the Development Planning Division of the Provincial Water Resources Department, said that Shandong Province will implement the most stringent ecological environmental protection system, build an estuary ecological protection zone based on the Yellow River Delta wetland, and promote the ecological function of the lower Yellow River. Enhance and improve the ecological environment of the estuary; explore the establishment of a flexible scheduling and utilization mechanism of the Yellow River water resources, vigorously develop agricultural water-saving industries and technologies, and implement the continuous construction and modernization of 11 large-scale irrigation areas such as Zibo Mazazi and Dongying Wangzhuang to ensure limited The Yellow River's water resources have maximized the benefits; with the main stream of the Yellow River, flood storage and detention areas, and tributary rivers as the framework, speed up the implementation of flood control and drought relief water conservancy upgrading projects, strengthen the construction of a comprehensive flood prevention and disaster reduction system, and comprehensively improve the comprehensive flood and drought disaster prevention and control capabilities. According to the "Plan", during the "14th Five-Year Plan" period, Shandong Province will further strengthen key water source projects, implement 37 large and medium-sized reservoir expansion projects including Yanma Reservoir, speed up the construction of Laolan Reservoir, and demonstrate the implementation of a batch of new reservoir projects. Construction of 89 river blocking projects including Zhuanshe river sluices. At the same time, in accordance with the national deployment, the implementation of the follow-up project demonstration of the east route of the South-to-North Water Transfer Project will be promoted, the layout of the main line projects in Shandong will be optimized, and the planning and construction of supporting projects in the province will be carried out in a timely manner. Based on the natural rivers and lakes in the region, strengthen the interconnection of regional water networks, demonstrate the implementation of 24 regional water network projects such as the connection of the four reservoirs in eastern Jinan; strengthen the connection with the provincial backbone water network, and build and improve the three levels of provinces, cities and counties The water network engineering system replenishes the water in the area with water from outside the area, replenishes the water in dry years with water from abundant years, and replenishes the water in scarce areas with water from the remaining area.
