青藏高原若尔盖高原典型土地利用类型和典型坡面植物群落调查数据（2019）

2019年7-8月，以若尔盖高原东缘红原县为科考点，选取典型土地利用类型的高寒草地和典型坡面设置样线，沿山顶至山脚每隔50m，对草地和湿地生态系统的植物群落特征进行调查，样方大小为50cm×50cm，3个重复，共调查植物样方63个,获取了植物种数、数量、地上生物量、多样性指数等，生物量采用烘干法。为研究不同海拔梯度及不同草地类型植物生产力及群落变化规律提供可靠数据。准确定量高寒草灌植被变化对植物群落、植被演变将有助于青藏高原草地生态系统多目标的优化管理。

From July to August 2019, field investigations were carried out in Hongyuan County, located on the eastern edge of the Zoige Plateau. We established sampling transects in typical alpine grasslands with representative land use patterns and typical slope sections. Vegetation community characteristics of grassland and wetland ecosystems were surveyed at 50-meter intervals from the mountain summit to the base, using 50 cm × 50 cm quadrats with three replicates per sampling position. A total of 63 plant quadrats were investigated throughout the survey. Collected metrics include plant species richness, individual abundance, aboveground biomass, and diversity indices, where aboveground biomass was determined using the oven-drying method. This dataset offers reliable data for studying the patterns of plant productivity and community changes along different elevation gradients and among distinct grassland types. Accurate quantification of changes in alpine grass-shrub vegetation, along with investigations into plant community and vegetation evolution, will facilitate multi-objective optimal management of grassland ecosystems on the Qinghai-Tibet Plateau.
