青藏高原土壤理化性质数据集（2019-2021）

本数据集包含2019-2021年青藏高原10条科考线路土壤样品的理化性质数据，包括采集人、采集时间、采集地点、经纬度、海拔、植被类型、取样深度、土壤含水量、pH、有机质含量、总碳含量、全氮含量、全磷含量、无机氮含量、重金属元素含量等信息。各项土壤性质的分析参考《土壤环境质量监测技术规范》的要求，通过室内化验分析获得的一手数据，数据质量通过测定空白样品、重复样品和标准样品进行统一控制。该数据集可用于气候变化和人类活动影响下土壤质量和功能评价。

This dataset contains physicochemical property data of soil samples collected along 10 scientific expedition routes on the Qinghai-Tibet Plateau from 2019 to 2021, with information including collectors, collection time, collection locations, latitude and longitude, altitude, vegetation type, sampling depth, soil moisture content, pH value, organic matter content, total carbon content, total nitrogen content, total phosphorus content, inorganic nitrogen content, and heavy metal element content. All soil property analyses were performed in accordance with the requirements of the Technical Specifications for Soil Environmental Quality Monitoring, and the raw data were obtained through laboratory assays. The data quality was uniformly controlled by measuring blank samples, duplicate samples, and certified reference materials. This dataset can be utilized for evaluating soil quality and functioning under the impacts of climate change and human activities.
