Core Viewpoint - The project aims to balance ecological protection with pipeline construction in the Guozi Valley, emphasizing innovative techniques to ensure harmony between energy infrastructure and natural ecosystems [1][3]. Group 1: Environmental Protection Measures - The forest coverage in Guozi Valley is 53%, home to 146 species of terrestrial vertebrates, prompting the National Pipeline Group to optimize the design by reducing 11 non-continuous tunnels to 4 continuous tunnels to minimize disturbance to wildlife [3]. - The project manager stated that all 800,000 cubic meters of excavated soil from the tunnel construction will be utilized, with part used for pipeline backfilling and the remaining 600,000 cubic meters transported out for local environmental restoration and urban construction, saving 26 hectares of construction land [5]. - The project team collaborates with government authorities and agricultural experts to implement genetic resource protection measures for local wild apple trees and Zungarian hawthorn, ensuring the preservation and recovery of these species [7]. Group 2: Construction Techniques and Sustainability - The project employs the least environmentally impactful equipment and materials, using underground grouting instead of surface grouting to avoid damaging surface vegetation and minimize impacts on sensitive ecological areas [9]. - During construction, the project maximizes the use of locally abundant green electricity, with green energy accounting for over 50% of the energy used, resulting in a reduction of nearly 10,000 tons of carbon dioxide emissions [10].
