Desert Uplands 1 Management Event Data Collection

<p>The Management Event collection for the ALTAR site Desert Uplands 1 provides a spatiotemporal summary of significant land management events in the managed agroecosystem. </p> <p>In cropping and grazing lands, management events, for example, grazing, tillage, mechanical harvest and burning often represent either (1) a considerable lateral transport of carbon and water from the monitored ecosystem or (2) a period when assumptions of the eddy covariance technique may not be met. Correct capture of these events also enables a valuable opportunity to improve understanding on management effects. For integration into simulation models, historical management event insight may be crucial, but sources may be highly uncertain.</p> <p>In practice, management event records are often inconsistent between producers and contain sensitive information – to enable sharing and analysis across multiple sites, ALTAR network processing involves translation and denaturing of this information before publication. </p> <p>Access to this dataset is available on request subject to agreement.</p>

ALTAR站点荒漠高地1号的管理事件数据集，针对人工管理农业生态系统内的重要土地管理事件提供时空汇总结果。
在耕作与放牧用地中，放牧、翻耕、机械收割与烧荒等管理事件通常兼具两种特征：其一，会导致监测生态系统内碳与水发生显著横向迁移；其二，会使得涡度协方差技术（eddy covariance technique）的适用假设不再成立。准确记录此类事件，还有助于深化对土地管理效应的认知。若要将管理事件数据集成至模拟模型中，历史管理事件的相关认知至关重要，但此类数据的来源往往存在较高不确定性。
实际应用中，不同数据提供者所提交的管理事件记录往往存在不一致性，且此类记录常包含敏感信息。为支持多站点间的数据共享与分析，ALTAR网络会在发布前对这类信息进行格式转换与脱敏处理。
