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]
