冰雪碰撞热情，凝结冬日幸福感

Core Viewpoint - The construction of the Beichuan Rainbow Ski Resort in Xining represents a significant development in the local winter tourism industry, combining advanced snow-making technology with a variety of recreational offerings to enhance the winter experience for residents and visitors [6][9]. Group 1: Snow-Making Technology - The ski resort utilizes six large snow-making machines that operate at night to create optimal snow conditions, as temperatures drop to between -3°C and -5°C, ensuring the snow is soft and easy to shape [8]. - The snow-making process involves compressing air and water to create fine mist droplets that quickly freeze upon contact with cold air, resulting in high-quality snow [6]. Group 2: Infrastructure Development - The resort features a range of facilities, including intermediate and beginner ski slopes, a family snow play area, and various entertainment options such as snow banana boats and mini-motorcycles, catering to diverse visitor needs [7]. - Construction activities are strategically scheduled, with snow-making occurring at night and infrastructure improvements taking place during the day to maximize efficiency and safety [8]. Group 3: Economic Impact - The development of the Beichuan Rainbow Ski Resort aligns with Xining's strategy to promote "ice and snow" tourism, transforming cold resources into a vibrant economic sector and enhancing winter tourism offerings [9]. - The ski resort is expected to become a new landmark for cultural tourism in Xining, attracting more visitors and providing a local recreational option, thereby contributing to the region's economic growth [9].
