Qinghai Province is an important part of the Qinghai-Tibet Plateau. To achieve the sustainable use of grassland resources in this region， it is important to explore the local grass-livestock balance and determine the spatial and temporal trends in the carrying capacity of its grassland ecosystem. In this study， we focused on animal husbandry in Qinghai Province， and combined remote sensing image data with livestock statistics to analyze the carrying state of grassland ecosystems in this province. It was found that： 1） According to the statistical yearbook provided by the Qinghai Provincial Bureau of Statistics， the number of grazing livestock in Qinghai Province increased by 25.35% between 2005 and 2020. In terms of livestock structure， Yushu Tibetan Autonomous Prefecture and Guoluo Tibetan Autonomous Prefecture are dominated by yak breeding， while Haibei Tibetan Autonomous Prefecture， Hainan Tibetan Autonomous Prefecture and Haidong City are dominated by sheep breeding. 2） The consumption of grassland resources in Qinghai Province increased by 13.21% over 16 years， showing an overall increasing trend with differences among administrative regions. 3） The number of prefectures with severe overloading of livestock in Qinghai Province dropped to fewer than three in 2010 for the first time， and the best overall grass-livestock balance was in 2013. In general， the animal-grazing pressure has decreased over time. Sorted by region， Hainan Tibetan Autonomous Prefecture showed the most obvious increase in carrying pressure， and Guoluo Tibetan Autonomous Prefecture showed the most obvious decrease in animal-grazing pressure. The results showed that the number of grazing livestock in Qinghai Province has increased between 2005 and 2020， but there has been a tendency for the grazing pressure to ease， with each administrative region showing some variability in livestock structure and changes in grazing pressure. This highlights the importance of adapting measures to local conditions. These results provide a scientific basis for the ecological management of alpine grasslands and the development of the livestock industry in Qinghai Province.
