数据集是黄土高原地区，包括陕西、宁夏、甘肃、河南、山西境内68个调查样点草地调查分析数据，其中陕西28个调查样点、宁夏21个调查样点、甘肃10个调查样点、河南4个调查样点、山西5个调查样点。数据内容包括样地编号、植物地上/地下有机碳，全氮、全磷、全钾含量，县级名称、地级名称、测定日期、经度、纬度、海拔、地貌地形、坡位、坡向、坡度、土壤类型、草原类、草原类型、遥感类型、植被群落名称、利用强度、利用方式等。数据为农业可持续发展和全球变化研究提供数据支撑。

This dataset comprises grassland survey and analytical data collected from 68 sampling sites across the Loess Plateau region, covering areas within Shaanxi, Ningxia, Gansu, Henan, and Shanxi provinces. Specifically, the sampling sites include 28 in Shaanxi, 21 in Ningxia, 10 in Gansu, 4 in Henan, and 5 in Shanxi. The dataset contains the following information: sampling plot number, aboveground and belowground organic carbon contents of plants, total nitrogen, total phosphorus and total potassium contents, county-level name, prefecture-level name, measurement date, longitude, latitude, altitude, geomorphology and terrain, slope position, slope aspect, slope gradient, soil type, grassland category, grassland type, remote sensing type, vegetation community name, utilization intensity, and utilization method. This dataset provides data support for research on agricultural sustainable development and global change.
