The Guangdong Water Resources Configuration Project is a major livelihood project that the people of western Guangdong are looking forward to. The starting point of the project is to improve people's livelihood, and the end of the foothold is also people's livelihood. What is directly benefited is the release of the people's life water, followed by the release of work, agricultural production and ecological environmental benefits. Liu Jianmei, deputy director of the Planning Institute of Planning and Design and Research Institute of Guangdong Province Water Conservancy Electricity Survey and Design Institute, introduced that the project is mainly based on urban and rural life and industrial water supply, taking into account agricultural irrigation, creating conditions for improving the ecological environment of the water, and achieving economic, social, ecological ecology, and ecology. Wait for the win -win results of multiple benefits.

According to the plan, the project has an average water diversion of 1.632 billion cubic meters from Xijiang for many years. In combination with local water conservancy facilities, it has achieved an average of 2.079 billion cubic meters of water supply in the water area, of which 1.438 billion cubic meters of water supply in urban and rural life and industrial water supply 641 million cubic meters.

The water resource allocation project of the north Bay Bay is transmitted to the western Guangdong region of Western Western Western Western Western Western Guangdong, which forms a multi -water source water supply pattern with local water sources, which will improve the water supply system of each city. Improving regional water supply safety and guarantee capabilities can effectively solve the problem of drinking water in the western Guangdong region. Liu Jianmei added that after the project was completed, the groundwater was reduced by 566 million cubic meters of groundwater each year, and the agricultural and ecological water volume of the city's occupied by the city could be returned to the city's squeezed agricultural and ecological water, making the rivers and lakes healthier and more secure. Greatly improve the conditions for agricultural production, ensure the stable production of ration fields in the core areas of the country such as Lianjiang, promote the increase of local farmers' income, and help consolidate the results of poverty alleviation.

According to the research results of the China Macroeconomic Research Institute, every 100 billion yuan of major water conservancy projects can drive GDP to increase by 0.15 percentage points and add 490,000 new jobs. Initially estimated that the water resource allocation project of the north Bay Bay has absorbed large investment and long industrial chain, which can drive GDP to increase by 0.09 percentage points, add 300,000 new jobs. It is of great significance for the development pattern of the area in the Belt and One District to promote stable economic stability.

Water transfer: the shortage of the shortage of water resources in the western western western water

Why should Guangdong, which is located in Fengshui District.

Zhanjiang, Maoming, Yangjiang, and Yunfu in the four cities in western Guangdong are important cities of the National Beibu Gulf urban agglomeration and the Pearl River -Xijiang Economic Belt. It is also an important part of the coastal economic belt of the new coastal economic belt of the "one core, one area and one district" area in Guangdong Province. In recent years, a large number of major industrial projects such as Zhanjiang Iron and Steel and China -Germany BASF have successively built, and have put forward higher requirements for water supply safety in western Guangdong.

However, due to the conditions of terrain conditions, the water systems of the coastal rivers in the area are mostly small and medium rivers, with short sources of rapid flow, weak natural storage capacity, and great changes. The bitter drought and water shortage, seriously restricted the high -quality development of the economy and society in the western Guangdong, affecting the coordinated development of Guangdong region. In particular, the Leizhou Peninsula has been a well -known place in the country since ancient times. However, at the same time, there is sufficient arable land resources and good light heat conditions. The shortage of water resources has become the main factor restricting the high -quality development of local agriculture and various industries. More than 60 years ago, the local 300,000 military people built the Leizhou Canal and collected the "double -pronged" of groundwater, which briefly rewritten the history of local bitter and dry. The Guangdong Provincial Party Committee and the Provincial Government have also adopted a series of drought treatment measures. In 1998, the implementation of the "Drought Treatment Plan for the Southwest of the Leizhou Peninsula" was launched. , Gradually improved the problems of drinking water and agricultural water in western Guangdong.

However, it is difficult for the canal to reduce the amount of water and strengthen water saving and local digging measures. It is difficult to fundamentally resolve the contradiction between the supply and demand of the local water resources, and the long -term superposition of the groundwater has laid a lot of hidden dangers.

The construction of a new water -related water project is imminent, and the Guangdong Water Resources Configuration Project around Beibu Gulf is from this. The layout of the project is mainly to solve the contradiction between the lack of matching of the landscape of the water resources of the western water resources and the economic and social development in the long run, and to achieve the coordinated development of urban regions.

Dreatment: The project creates the most in Guangdong

As the largest national water conservancy project in Guangdong, which is the largest in China, and the industry's attention, what technical difficulties will the Guangdong Water Resources Configuration Project around Beibu Gulf?

Liu Jianmei introduced that the towering clouds opened the mountains, the peaks and mountains were crowded, and the water flow lines crossed the mountains and crossed the mountains. It was hundreds of kilometers. The project construction problem was not small. The geological survey and research of multi -phase complex erosion turbidity belt engineering, the research and design of the lining structure of high water pressure tunnels under complex hydrogeological conditions, through the development and construction of long -distance deep buried tunnel under complicated geological conditions R & D and applications of power centrifugal pumps, long -distance deep -buried pipeline smart operation and maintenance and guarantee, including the six major industries and other industries and even world -class difficulties and challenges. For example, Xijiang takes a water flow of 110 cubic meters per second, 162 meters, the single pump design flows 22 cubic meters per second, and the single pump power is 48 MW.

On June 28, 2020, the Guangdong Provincial Department of Water Resources issued the preliminary work plan for accelerating the promotion of the Guangdong water resources allocation project around Beibu Gulf to compact various goals and tasks. In order to solve engineering technical problems, the project selected scientific research institutes and well -known universities through public bidding methods to conduct scientific research from 6 categories and 21 items.

Yuehai Group organizes the expert technical team to investigate and exchange the engineering trunk lines and division of engineering engineering lines. Zhongshui and Pearl River -Guangdong Water Conservancy Power Design Institute invested more than 600 people teams. The charts were fighting, and the implementation of various tasks was promoted day and night. "Guangdong Speed". In response to the key difficulties of design, construction, and operation and maintenance, the design team relied on scientific and technological innovation to compile the "Outline of the Scientific Research Research on the Configuration Engineering of Water Resources Configuration in Beibu Gulf" to escort the engineering design plan and construction management.

At present, the relevant scientific research work of engineering construction has been fully launched, focusing on scientific research on major technical problems.
