摘　　要：中国“双碳”目标的提出立足于应对气候变化的科学基础之上,增加碳汇、减少碳源成为实施气候治理的必需。陆地生态系统是重要的大气碳汇,而热带季节雨林生态系统作为中国陆地生态系统的组成部分,具有生物量丰富、生产力旺盛等特征,发挥着不可或缺的固碳功能。西双版纳热带季节雨林生态站是中国通量研究网络(ChinaFLUX)的首批成员站之一,自2002年建成至今已积累20年碳水通量观测数据。本数据集遵循ChinaFLUX数据处理体系,处理并汇整了西双版纳热带季节雨林2011年1月至2015年12月的标准化通量和常规气象数据,形成的数据产品包含4种时间尺度(30分钟、日、月和年)。本数据集可应用于全球变化背景下的生态系统碳水循环响应机制分析和固碳效益评估等研究领域,也可为生态系统模型参数优化和结果验证提供参考。通过多平台架构、多尺度融合、多方法耦合,以期进一步为解析区域乃至全球生态系统碳水热循环机制、时空动态和预估未来碳汇潜力提供基础支撑,从而为达成中国碳中和目标提供科学依据。The proposal for China's dual-carbon target is based on the foundation of addressing climate change.It is imperative to enhance carbon sinks and reduce carbon sources to implement climate governance.The terrestrial ecosystem is an important atmospheric carbon sink,while the tropical seasonal rain forest,as a component of the terrestrial ecosystem in China characterized by rich biomass,and strong productivity,plays an essential role in carbon sequestration.As one of the basic observation and research stations of China Flux Research Network(ChinaFLUX),the Xishuangbanna Tropical Seasonal Rainforest Ecological Station built in 2002 has accumulated 20 years of carbon and water flux observation data.Based on the ChinaFLUX data processing system,this dataset processes and collates the tropical seasonal rain forest flux and conventional meteorological data of Xishuangbanna from January 2011 to December 2015.The result is a collection of data products at half-hourly,daily,monthly,and yearly intervals.This dataset can be applied to research fields such as the analysis of the carbon cycle response mechanism of ecosystems and the assessment of carbon sequestration benefits under climate change,and it can also serve as a valuable reference for the optimization of ecosystem model parameters and the verification of results.Through multi-platform architecture,multi-scale integration,and multi-method coupling,the dataset is expected to further provide basic support for analyzing the mechanisms of regional and even global carbon-water-heat cycles in ecosystems,spatiotemporal dynamics and predicting future carbon sink potential,thus providing the scientific basis for achieving China's carbon neutrality goal.
