Core Viewpoint - The article highlights the continuous growth and development of Nagqu, the highest prefecture-level city in China, located in Tibet, emphasizing its unique geographical and environmental characteristics [1]. Group 1: Geographic and Environmental Features - Nagqu is situated in northern Tibet and is named after the Nagqu River, a tributary of the upper Yangtze River, making it the highest prefecture-level city in China with an elevation of 4,510 meters [1]. - The region is characterized by an average elevation exceeding 4,000 meters, and it continues to rise annually due to tectonic activity [1]. - Nagqu hosts several geographical records, including the highest county in China (Shuanghu County), the largest glacier in the mid-latitudes (Puruogangri Glacier), and the highest freshwater lake in the world (Cuona Lake) [1]. Group 2: Challenges of High Altitude Living - The high altitude results in low oxygen levels, with air containing only half the oxygen of sea level, and an average annual temperature below zero degrees Celsius [1]. - The region experiences a relative humidity of around 50% and over 100 days of strong winds annually, with the boiling point of water at approximately 85 degrees Celsius [1]. - Due to the lack of oxygen, residents often experience physical challenges, such as increased heart rates and changes in lip color [2]. Group 3: Urban Development and Greening Efforts - Historically, Nagqu was the only prefecture-level city in China without trees due to its harsh environment, characterized by a thick permafrost layer that hindered tree growth [3]. - Through concerted efforts, Nagqu has successfully achieved urban greening, introducing various tree species such as highland willows, spruces, and sea buckthorns, which have enhanced the city's liveliness and visual appeal [4]. - The presence of trees has transformed the urban landscape, contributing to a more dynamic and vibrant city atmosphere, as evidenced by community activities and the gathering of wildlife [4][5].
