西部大省 又一个“超级工程”来了

Core Viewpoint - The Chengdu Plain is facing a severe water shortage despite being known as a "province of a thousand rivers," with projections indicating a significant deficit by 2035 [1][8]. Water Resource Distribution - Sichuan province has a total water resource volume that ranks second nationally, but its distribution is uneven, with the Chengdu Plain accounting for 80% of the GDP while only having 20% of the water resources [1][7]. - The average annual water resource volume in Sichuan is substantial, yet the majority of the province's economic activities are concentrated in the basin area, leading to pronounced supply contradictions [2][7]. Water Supply Projects - The "Yin Da Ji Min" project has been officially approved, marking the largest investment and longest water diversion project in Sichuan's history, aimed at alleviating the water shortage in the Chengdu Plain [2][9]. - This project will benefit over 34 million people across eight cities and 43 counties, establishing a dual-source water supply system [2][9]. Future Projections - By 2030, the Chengdu Plain's population is expected to exceed 23.3 million, leading to an estimated annual water supply gap of approximately 2.3 billion cubic meters [7][8]. - The Chengdu water resource per capita is projected to be around 600 cubic meters, with a forecasted shortage of 1.2 to 1.67 billion cubic meters by 2035 [1][8]. Infrastructure Development - The "Yin Da Ji Min" project is part of a broader strategy to reshape Sichuan's water network, with a total length of 260.9 kilometers and an estimated investment of 57.519 billion yuan [9][11]. - The project aims to enhance water resource allocation and improve the irrigation area significantly, impacting over 34 million people [9][11]. National Water Resource Strategy - The national water resource strategy includes multiple major projects aimed at addressing regional water shortages, with a focus on cross-regional water diversion [17][18]. - The ongoing construction of various water projects reflects a trend towards building a modern water network to resolve supply-demand contradictions in water resources across different regions [17][18].
