青海草地土壤理化性质（2019-2020）

本数据集包含2019-2020年在青海省草地科考线路土壤样品的的理化性质数据，包括采集时间、采集地点、经纬度、海拔、植被类型、取样深度、土壤含水量、pH、总碳含量、全氮含量、无机氮含量等土壤理化数据信息。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 the grassland survey routes in Qinghai Province during 2019–2020. The included indicators cover collection time, sampling location, longitude and latitude, altitude, vegetation type, sampling depth, soil moisture content, pH, total carbon content, total nitrogen content, inorganic nitrogen content and other soil physicochemical parameters. All soil property analyses were conducted in compliance with the requirements of *Technical Specifications for Soil Environmental Quality Monitoring*, and the raw data were obtained through laboratory assays. The data quality was uniformly controlled by testing blank samples, duplicate samples and standard reference materials. This dataset can be used to evaluate soil quality and function under the influences of climate change and human activities.
