摘　　要：碳水通量是生态系统与大气间碳水交换量,是量化生态系统功能及其对全球气候变化的重要参数。热带季节雨林是我国重要的生态系统类型,在区域气候调节、碳汇吸收中具有重要作用。西双版纳生态站是中国生态系统观测网(CERN)和中国通量观测研究网络(ChinaFLUX)的基础观测站点,基于涡度相关技术,已开展了17年碳水通量观测工作。本文基于ChinaFLUX数据处理体系,报道了2003–2010年西双版纳热带季节雨林碳水通量数据集的处理过程、数据结构及使用建议。本数据集经过坐标轴旋转、异常值剔除、数据插补等标准数据处理,形成了30分钟、日尺度、月尺度和年尺度4个时间尺度数据,涵盖生态系统净碳交换量、生态系统呼吸、生态系统碳交换总量、蒸散、显热等碳水通量及气温、辐射等相关气象要素。本数据集不仅可以服务于区域生态系统功能评估、模型参数优化,还服务于地方经济发展、生态安全、政府决策等,并在高质量论文、专著和国家及省部级奖项方面取得了丰硕的成果。本数据集是面向国家重大发展战略和服务地方应用的有力支撑。Carbon and water fluxes,the carbon-water exchange capacity between ecosystem and atmosphere,are an important parameter to quantify ecosystem function and its global Climate Change.Tropical seasonal rainforest is an important ecosystem type in China,which play an important role in regional climate regulation and carbon sequestration.Xishuangbanna Ecological Station,as the basic observation station of China ecosystem observation Network(CERN)and China Flux Research Network(ChinaFLUX),has carried out carbon and water fluxes observation work based on Eddy Covariance Technique,for 17 years.Based on ChinaFLUX data processing system,this paper reports the processing process,data structure and application suggestions of carbon and water fluxes dataset of tropical seasonal rainforest in Xishuangbanna from 2003 to 2010.We accumulated in the dataset four time-scale data,namely half-hour,daily,monthly and yearly scales through standard data processing,such as coordinate axis rotation,abnormal value elimination,data interpolation and so on.It covers net ecosystem carbon exchange,ecosystem respiration,gross ecosystem carbon exchange,evaporation,sensible heat and other related meteorological factors,such as temperature,radiation and so on.This dataset can not only serve the regional ecosystem function assessment,model parameter optimization,but also promote the local economic development,ecological security,government decision-making etc.,with fruitful results in high-quality papers,monographs and national and provincial awards.it is a powerful support for major national development strategies and local applications.
