超级工程重塑四川经济地理

Core Viewpoint - The completion of several major infrastructure projects in Sichuan by the end of 2025 marks a significant advancement in the region's transportation and energy capabilities, enhancing its economic geography and strategic importance in national development [5][20]. Infrastructure Development - The Jinshang-Hubei ±800 kV UHVDC project, completed on December 18, 2025, enables clean electricity to be transmitted 1,900 kilometers to East China in just 6 milliseconds, setting a record for the highest altitude UHV project [1]. - The Leshan-Xichang Expressway, which opened on December 31, 2025, features a high bridge-tunnel ratio of 82% and incorporates innovative heating systems to address winter snow challenges [3]. - Sichuan has invested nearly 8.8 trillion yuan in over 1,600 key provincial projects during the 14th Five-Year Plan, with over 4 trillion yuan already completed, focusing on transportation, energy, water resources, and new infrastructure [5]. Energy Sector Advancements - By December 19, 2025, Sichuan's hydropower installed capacity surpassed 100 million kilowatts, making it the first province in China to reach this milestone, capable of supplying electricity for approximately 500 million people annually [17]. - The province's total power generation capacity exceeded 150 million kilowatts by the end of 2025, marking significant progress in transitioning to a clean energy structure [18]. Transportation Network Expansion - The completion of the Chengdu-Yibin high-speed railway and the operation of the Yuxi-Kunming high-speed railway have significantly improved connectivity in the region, with the Chengdu-Yibin line alone transporting over 29 million passengers in two years [9][11]. - Sichuan's highway network has expanded by over 3,000 kilometers in five years, connecting 15 previously isolated counties to national transportation arteries [12]. Economic Impact - The development of these infrastructure projects is expected to stimulate local economies, with increased tourism evidenced by over 7 million visitors to Jiuzhaigou in 2025, a 27% increase year-on-year [14]. - The establishment of the Chengdu-Europe Railway Express has facilitated the export of various goods, including agricultural products, to over a hundred cities globally, enhancing Sichuan's role in international trade [15]. Environmental Considerations - Infrastructure projects in Sichuan are increasingly incorporating green development principles, such as the relocation of power lines to protect migratory bird pathways and the successful transplantation of endangered plant species [22].
