为3万余只候鸟迁徙让路 成达万高铁7条高压线后退6公里

Core Points - The article discusses the successful completion of the power line relocation project for the Chengdu-Dazhou-Wanzhou high-speed railway, specifically the 500 kV Nanchong-Changpingshan line, which was adjusted to protect migratory birds in the Fengyi Bay Ecological Wetland [7][8] - The project involved moving seven high-voltage lines back by 6 kilometers to avoid a critical migratory path for nearly 60 species of birds, including the black-faced spoonbill and black stork, which migrate through the area from October to March [7][8] Group 1 - The original design of the power lines posed a risk to migratory birds due to their proximity to a key migration route, leading to potential bird collisions with the high-voltage lines [7] - The decision to alter the power line routes was made quickly by local government and project companies to prioritize the safety of the migratory birds [7][8] - The new design maintains a distance of over 700 meters from the wetland and reduces the height of new towers and lines to minimize collision risks and electromagnetic field impacts on the birds [8] Group 2 - The Chengdu-Dazhou-Wanzhou high-speed railway is a significant part of China's "eight vertical and eight horizontal" high-speed rail network and supports national strategies such as the development of the Yangtze River Economic Belt and the Chengdu-Chongqing economic circle [8] - The railway line spans 486.4 kilometers with a design speed of 350 kilometers per hour, highlighting its importance in regional connectivity and economic development [8]
