Data for: Terrain units, land use and land cover, and gross primary productivity of the Araguaia River Basin

This data set was produced with the aim of integrating the landscape structural and functional factors with the GPP dynamics over different terrain units in the Araguaia River Basin. Studies were conducted through the integration of different databases, including the topographic domains, protected areas and indigenous lands; land use/cover map (year 2016); time series of GPP derived from the Moderate Resolution Imaging Spectroradiometer (MODIS) sensor (period of 2000–2015); Shuttle Radar Topography Mission (SRTM) digital elevation models (DEM); and precipitation data produced by the WorldClim version 2 dataset. GPP time series were processed using statistical methods of time series decomposition. The dataset contributes to the understanding of the linkages between land use changes and carbon cycles by considering land use as a response of how the landscape is organized. Our data may provide subsidies for further studies on carbon budget, conservation of biodiversity, and rational use of natural resources.

本数据集旨在整合阿拉瓜亚河流域（Araguaia River Basin）不同地貌单元的景观结构、功能因子与总初级生产力（Gross Primary Productivity, GPP）动态变化规律。本研究通过整合多源数据库完成相关分析，所用数据集涵盖地形分区、保护区与原住民土地数据；2016年土地利用/覆盖图；中分辨率成像光谱仪（Moderate Resolution Imaging Spectroradiometer, MODIS）获取的2000–2015年GPP时间序列数据；航天飞机雷达地形测绘任务（Shuttle Radar Topography Mission, SRTM）数字高程模型（Digital Elevation Model, DEM）；以及WorldClim版本2数据集生成的降水数据。GPP时间序列采用时间序列分解的统计方法进行预处理。本数据集将土地利用视为景观格局组织方式的响应指标，有助于阐明土地利用变化与碳循环之间的关联机制。本数据集可为碳收支、生物多样性保护以及自然资源合理利用等领域的后续研究提供数据支撑。
