青藏高原草地资源与环境数据集（2019-2023）

青藏科考青藏高原草地植被调查数据集（2019-2023）由第二次青藏科考任务三专题二子专题一的科考队于2019-2023年的野外调查完成。该数据集覆盖了青藏高原草地、荒漠等典型植被类型，由西藏、青海、甘新、川西四个片区组成，共计600个样点，3026个调查样方。数据集由五部分组成，包括草地生态系统样地信息、分种地上植被信息、不分种地上植被信息、地下根系、土壤理化性质等，包括：地上、地下生物量，群落物种组成与多样性，植物（含根系）和土壤样品C、N、P含量，土壤pH、容重、砾石比和土壤无机碳等数据。数据质量完好，可用于计算生物多样性和驱动因素分析。

The Tibetan Plateau Grassland Vegetation Investigation Dataset (2019–2023) from the Second Tibetan Plateau Scientific Expedition and Research was developed based on field surveys conducted by the expedition team under Sub-sub-theme 1 of Sub-theme 2, Task 3 between 2019 and 2023. This dataset covers typical vegetation types on the Tibetan Plateau including grasslands and deserts, and is divided into four regional sections: Tibet, Qinghai, Gansu-Xinjiang, and western Sichuan, with a total of 600 sampling sites and 3026 survey quadrats. The dataset consists of five parts: plot information of grassland ecosystems, above-ground vegetation data categorized by species, above-ground vegetation data without species classification, underground root system data, and soil physicochemical property data. The collected indicators include above-ground and below-ground biomass, community species composition and diversity, C, N and P contents of plant (including root) and soil samples, as well as soil pH, bulk density, gravel content, soil inorganic carbon and other related parameters. The dataset has good data quality and can be used for biodiversity calculation and driving factor analysis.
