摘　　要：湿地生态系统对于缓解全球气候变化具有重要作用,长期、连续的碳水通量涡度监测有助于更好地保护和利用湿地生态系统的服务功能。然而,由于相关监测数据数量的欠缺,关注湿地生态系统碳水通量变化的研究还相对较少,因此亟需高质量的监测数据集提供支持。中国科学院黄河三角洲滨海湿地生态试验站(简称黄河三角洲站)自2010年起基于涡度协方差技术开始对芦苇湿地生态系统进行连续监测,迄今已积累了多年的碳水通量观测数据。本数据集基于黄河三角洲站已进行的监测工作,汇总整理了2011–2018年间的站点碳水通量涡度观测数据,并形成了半小时尺度、日尺度、月尺度和年际尺度4种时间分辨率下的数据产品。本数据集对准确评估黄河三角洲湿地生态系统的碳水通量及其各时间尺度上的动态变化规律提供了可靠的数据支撑。Wetland ecosystems play an important role in mitigating global climate change.Long-term monitoring of carbon and water fluxes through eddy covariance(EC)proves helpful for better preservation and sustainable utilization of wetland ecosystem services.However,there is a shortage of data and studies focusing on carbon and water fluxes in wetland ecosystems.Hence,there is an urgent need to furnish researchers with more observational data.The Yellow River Delta Ecological Research Station of Coastal Wetland,Chinese Academy of Sciences(hereinafter referred to as the Yellow River Delta Station),established an open-path EC system in a Phragmites australis wetland in 2010 and accumulated large amounts of flux data to date.The EC-based dataset in this paper comprises ecosystem-scale carbon and water fluxes at the study site spanning from 2011 to 2018.Moreover,all the data are presented at four time scales,i.e.,half-hourly,daily,monthly,and yearly.This dataset is of great importance for estimating carbon and water fluxes in wetland ecosystems and examining flux variations at different time scales.
