Core Insights - The area of artificial grassland in the Qinghai-Tibet Plateau has increased by 2.4 times from 1988 to 2021, with significant growth observed in Qinghai Province [1][2] - The study highlights the ecological impact of the rapid development of artificial grasslands as a response to the degradation of natural grasslands due to climate change and human activities [1] Summary by Sections - **Artificial Grassland Expansion**: By 2021, there are 1.57 million hectares of artificial grassland in Qinghai Province and Tibet Autonomous Region, with Qinghai accounting for 70% and Tibet for approximately 30% [2] - **Geographical Distribution**: Artificial grasslands in Qinghai are concentrated around favorable water and heat conditions, particularly around Qinghai Lake, Qilian Mountains, Hainan Prefecture, and Huangnan Prefecture. In contrast, those in Tibet are more dispersed, found in northern and southeastern Tibet, as well as river basins like the Yarlung Tsangpo and Lhasa rivers [2] - **Research Methodology**: The research utilized a random forest binary classification model with a high overall accuracy of 97% for mapping artificial grasslands, based on satellite remote sensing data collected over 34 years [1] - **Future Research Directions**: The study indicates a need for further scientific evaluation of the ecological and environmental effects resulting from the transition of natural grasslands to artificial grasslands, as existing statistical data may not fully align with remote sensing data [2] - **Theoretical Support for Development**: The findings provide essential spatial distribution information of artificial grasslands, supporting ecological protection and high-quality development of grassland livestock farming in the Qinghai-Tibet Plateau [2]

Core Viewpoint - The Chongqing Longxing Football Stadium, designed with the theme of "mountains and rivers," will host the 2026 World Cup qualifiers between China and Bahrain, showcasing a unique architectural style that reflects the local culture and environment [1][18]. Design and Architecture - The stadium covers an area of approximately 303 acres and features a design inspired by the mountainous terrain of Chongqing, with a tiered structure that mimics the natural landscape [1][5]. - The exterior uses parametric design with perforated aluminum panels to simulate the rough texture of mountain rocks, while the roof's wavy profile symbolizes the confluence of the Yangtze and Jialing Rivers [1][3]. - The seating arrangement is designed to ensure optimal sightlines for all spectators, with no obstructed views, enhancing the overall viewing experience [5][8]. Fan Experience - The stadium includes a "Super Fan Stand" with nearly 10,000 seats, making it the largest single stand in the country, designed to showcase fan culture and support for the national team [8]. - A large TIFO display is planned for the match, which will serve as a significant visual element during the game [8]. Turf and Maintenance - The stadium features a high-quality Bermuda grass pitch, which is currently being nurtured by a professional team, ensuring it meets FIFA standards for the upcoming match [10][12]. - The grass is designed to withstand high temperatures and provide a stable playing surface, with advanced drainage and ventilation systems in place to maintain optimal growing conditions [14][16]. Cultural Significance - The Longxing Football Stadium is not just a sports venue but a cultural symbol for the city, embodying the spirit of Chongqing and leaving a unique mark in sports architecture [18].
