产经观察·收官之际看工程丨东北省际高铁首次形成闭环

Core Viewpoint - The article emphasizes the importance of major infrastructure projects, such as the Shen-Jia high-speed railway, in promoting investment, employment, and regional development, while also enhancing connectivity and tourism in Northeast China [1][6]. Group 1: Infrastructure Development - The Shen-Jia high-speed railway, spanning approximately 430 kilometers, connects key cities in Liaoning and Jilin provinces, forming a closed-loop high-speed rail network in Northeast China [2][6]. - The railway significantly reduces travel time, making it easier for tourists from major urban areas like Beijing to access destinations such as Changbai Mountain [4][7]. - The opening of the Shen-Jia high-speed railway marks a milestone in the "14th Five-Year Plan," enhancing the connectivity of the Northeast region and making Liaoning the first province in the area to achieve full high-speed rail coverage [6][8]. Group 2: Economic and Tourism Impact - The railway is expected to boost local tourism, with increased accessibility leading to higher visitor frequency to attractions like Changbai Mountain and other cultural sites along the route [7][8]. - In its first month of operation, the Shen-Jia high-speed railway transported over 660,000 passengers, indicating strong demand and potential for economic growth in the region [8]. Group 3: Technological Innovations - The construction of the Shen-Jia high-speed railway involved the application of advanced technologies to address challenges posed by the region's harsh climate, including frost and snow [9][10]. - New construction techniques and automated systems were implemented to enhance efficiency and reduce material waste during the building process [10][11]. Group 4: Environmental Considerations - The project incorporates eco-friendly designs, such as sound barriers to protect endangered species like the Chinese merganser, demonstrating a commitment to environmental sustainability [11][12]. - Efforts were made to preserve local flora during construction, including the use of tunneling methods to avoid damaging ancient trees [13][14]. - The railway's design features a high bridge-to-tunnel ratio, minimizing land disruption and promoting harmony with the natural landscape [14].
