1998-2008年陕西长武站作物收获期监测数据

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》之陕西长武站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。本数据产品包含了陕西长武站按照CERN长期监测指标体系和规范开展的陕西长武农田生态系统主要作物矿质元素含量与能值、收获期测产、收获期植株性状的长期监测数据。数据范围自1998年至2008年。作物收获期监测数据是黄土高原南部高塬沟壑区农田生态系统的重要参数，可为黄土高原南部高塬沟壑区农田生态系统研究提供基础数据支撑。本数据产品同时包含长武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 digitally processed based on Volume 1 of Shaanxi Changwu Station from the *Farmland Ecosystem Volume* of the *China Ecosystem Fixed Observation and Research Dataset Series*, and was developed by refining metadata and associating it with entity data. This data product contains long-term monitoring data on mineral element contents and energy values of major crops, harvest-time yield measurements, and plant traits at harvest for the farmland ecosystem at Changwu Station, Shaanxi, which was collected in accordance with the long-term monitoring indicator system and specifications of CERN. The data covers the period from 1998 to 2008. The crop harvest-stage monitoring data serves as important parameters for the farmland ecosystem in the southern Loess Plateau’s high-tableland gully region, and can provide basic data support for research on the farmland ecosystem of this region. This data product also includes associated documents that introduce the observation sites at Changwu Station and elaborate on the methods and processes for acquiring the observation indicators.
