| Summary: | In recent years, intensified human activities on the Qinghai – Tibet Plateau have threatened its ecological environment. Traditional methods struggle to capture the dynamic diversity of activity types. In this study, we constructed daily and annual human activity time series on the Qinghai–Tibet Plateau via Tencent location request (TLR) data. By applying clustering algorithms, we classified daily patterns into three main types. Daily pattern areas show a pronounced nighttime peak – reflecting agricultural and residential activities – while mobility pattern areas peak only by day and remain flat at night, indicating tourism and frequent movement. Regions below 2800 m combine daily and tourism patterns, whereas areas above 3500 m are dominated by the dispersed residential pattern, characterized by scattered grazing. Annual patterns is classified into urban pattern and rural pattern. Both show similar request volumes, but the urban pattern has a higher proportion of built-up land, and Lunar New Year population migration produces marked variations in request counts. This study distinguishes key human-activity patterns and provides novel methods and insights for understanding activity regularities on the Qinghai – Tibet Plateau. |
