A dataset of Plant Community sampling survey in Alpine Meadow on Qinghai Tibet Plateau（2007–2022）

The Gansu Gannan Grassland Ecosystem National Observation and Research Station conducts long-term monitoring of plant species composition and plant community characteristics of the Maqu alpine meadow ecosystem in Gannan, Gansu Province, following the standardized protocols of the Chinese Ecosystem Research Network (CERN). This study compiles data from fixed sample plots collected between 2007 and 2022, including plant species composition, height, coverage, abundance, and aboveground biomass. The objective of this study is to provide a scientific basis and data support for the management and restoration of alpine meadows.
