1998-2008年辽宁沈阳站土壤化学性质监测数据

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《农田生态系统卷》之辽宁沈阳站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。本次出版的土壤化学性质监测数据包括以下要素：阳离子交换量、养分含量、矿质全量、微量元素、重金属、速效微量、硝态氮、铵态氮。时间范围：1998年1月~2008年12月（如果需要其他时段或要素，请直接与沈阳站联系）。本数据产品同时包含沈阳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 via digitized processing based on Volume 1 of the Liaoning Shenyang Station section under the *Farmland Ecosystem Volume* of the *China Ecosystem Fixed Observation and Research Dataset* series, by refining metadata and establishing associations with physical entity data. The soil chemical property monitoring data released in this edition includes the following parameters: cation exchange capacity (CEC), nutrient content, total mineral elements, trace elements, heavy metals, available trace elements, nitrate nitrogen (NO₃⁻-N), and ammonium nitrogen (NH₄⁺-N). The time coverage spans from January 1998 to December 2008. Please contact the Shenyang Station directly if you need other time periods or parameters. This data product also includes supporting documents that introduce the Shenyang Observation Station and elaborate on the acquisition methods and processes of the observation indicators.
