摘　　要：陆地生态系统与大气间水分、热量和二氧化碳交换过程是陆地表层物质与能量交换的核心内容。涡动相关系统已成为当前测算陆地生态系统水热碳交换过程的首选方法之一。本数据集是中国通量观测研究联盟(ChinaFLUX)临泽内陆河流域研究站点河西走廊中部绿洲农田生态系统2012–2015年的水分、热量和二氧化碳通量,以及辅助微气象观测数据集。本数据集为深刻理解干旱区绿洲农田生态系统水分传输、能量交换、碳循环过程及其植物与环境调控机理提供了关键基础数据,对深入认识干旱区绿洲水文循环、生态–水文相互作用和气候变化中的碳水热耦合机制等具有重要科学价值。本数据集也可为干旱区绿洲水土资源管理、绿洲稳定与可持续发展、绿洲生态保护等干旱区所亟待解决的水资源短缺和生态环境脆弱等现实问题提供科学数据支撑。The exchange of water,heat,and carbon dioxide between the terrestrial ecosystems and the atmosphere is a fundamental process that underlies mass and energy transfer at the Earth’s surface.The eddy covariance technique has become one of the preferred and state-of-the-art approaches for measuring and calculating the exchange of water,heat,and carbon between the land surface and the atmosphere.This dataset covers the fluxes of water,heat,and carbon dioxide in an oasis agroecosystem,as well as the auxiliary micrometeorological variables in the middle areas of the Hexi Corridor during 2012–2015.The experimental observation campaign was carried out by the Linze Inland River Basin Research Station,a member station of the China Flux Observation and Research Network(ChinaFLUX).The dataset serves as a fundamental source of data,enabling in-depth comprehension water transfer,energy exchange,carbon cycle processes in the oasis agroecosystem in arid regions,and even their environmental and vegetation controlling mechanisms.It offers valuable insights into better understanding hydrological processes,ecosystem-hydrology reaction and discovering the coupling between carbon,water and heat in the context of climate change.Furthermore,the dataset holds significant scientific value in addressing chronic practical challenges related to fragile environment and shortage of water resource,such as water and land resources management,the preservation of oasis stability and sustainable development,the conservation of oasis ecosystems,etc.
