2000-2006年黑龙江三江站土壤理化分析数据

本数据产品是在《中国生态系统定位观测与研究数据集》丛书的《湖泊湿地海湾生态系统卷》之黑龙江三江站1册的基础上进行数字化加工，通过完善元数据并与实体数据相关联，生产了本数据产品。本次出版的土壤理化分析数据包括三江站观测场2000-2006年土壤理化性质数据，包括土壤交换量、土壤养分、矿质全量、微量元素及重金属、土壤溶解性有机碳、土壤速效微量元素、机械组成、土壤容重等数据，时间范围：2000-2006年（如果需要其他时段或要素，请直接与三江站联系）。本数据产品同时包含三江站观测点介绍及观测指标获取方法与过程的关联文档。

This data product was developed through digitized processing based on Volume 1 of Heilongjiang Sanjiang Station in the *Lake, Wetland and Bay Ecosystem Volume* of the *China Ecosystem Long-term Observation and Research Data Set* series, by optimizing metadata and associating it with corresponding entity data.
The published soil physicochemical analysis data covers soil physicochemical property data collected at Sanjiang Station's observation field from 2000 to 2006, including soil exchange capacity, soil nutrients, total mineral elements, trace elements and heavy metals, soil dissolved organic carbon (DOC), soil available trace elements, soil mechanical composition, soil bulk density and other related indicators. The data spans 2000-2006. For requests for other time periods or required parameters, please contact Sanjiang Station directly.
This data product also includes introductions to Sanjiang Station's observation sites and relevant documents detailing the acquisition methods and workflows of the observation indicators.
