白洋淀水土数据

本数据基于白洋淀湿地 9 个土壤/底泥样点与 8 个地表水样点的系统采样与实验室测定，记录 pH、有机质、速效/全量氮磷钾及铅、砷、汞、铬、镉等重金属含量，同时包含水体高锰酸盐指数、氨氮、总氮、总磷、COD 等富营养化指标，为评估湿地水土环境质量与生态风险提供基础数据。

This dataset is established based on systematic sampling and laboratory assays of 9 soil/sediment sampling sites and 8 surface water sampling sites in the Baiyangdian Wetland. It records the concentrations of pH, organic matter, available/total nitrogen, phosphorus, potassium, and heavy metals including lead, arsenic, mercury, chromium, cadmium, etc. Additionally, it covers eutrophication-related indicators of water bodies such as permanganate index, ammonia nitrogen, total nitrogen, total phosphorus, and Chemical Oxygen Demand (COD). This dataset provides fundamental data for assessing the soil and water environmental quality and ecological risks of the wetland.
