青藏高原西部土壤碳氮含量观测数据集（2019-2020）

本数据集涵盖了青藏高原西部176个采样点0-10厘米土壤深度的土壤碳和氮含量信息。这些土壤样本由研究团队在2019年至2020年期间通过土壤打钻的方法获得，并经过2毫米孔径筛筛选后，进行了风干处理和细根剔除。随后，在实验室中使用碳氮分析仪对样本进行了测定。这些数据为未来全球气候变化情景下研究青藏高原西部不同深度土壤碳氮过程提供理论基础，同时为模型模拟土壤碳氮循环过程提供数据支持，有助于深入理解青藏高原西部土壤碳氮循环过程。

This dataset contains soil carbon and nitrogen content data from 176 sampling sites at 0–10 cm soil depth in the western Qinghai-Tibet Plateau. The soil samples were collected by the research team via soil drilling between 2019 and 2020, and were passed through a 2-mm mesh sieve, followed by air-drying and removal of fine roots. Subsequently, the samples were analyzed using a carbon-nitrogen analyzer in the laboratory. These data provide a theoretical basis for investigating soil carbon and nitrogen dynamics at different soil depths in the western Qinghai-Tibet Plateau under future global climate change scenarios, offer data support for model simulations of soil carbon and nitrogen cycles, and contribute to a deeper understanding of soil carbon and nitrogen cycling processes in this region.
