A dataset of carbon and water fluxes observed in Xishuangbanna tropical seasonal rain forest from 2011 to 2015

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.中国双碳目标（China's dual-carbon target）的提出，以应对气候变化为根本依托。开展气候治理亟需增强碳汇（carbon sink）、削减碳源（carbon source）。陆地生态系统是重要的大气碳汇，而作为中国陆地生态系统组成部分的热带季节性雨林，凭借其丰富的生物量与强劲的生产力，在固碳（carbon sequestration）过程中发挥着关键作用。作为中国通量观测研究网络（China Flux Research Network, ChinaFLUX）的基础观测研究站点之一，2002年建成的西双版纳热带季节性雨林生态站已积累了20年的碳水通量观测数据。本数据集依托中国通量观测研究网络的数据处理体系，对2011年1月至2015年12月期间西双版纳热带季节性雨林的通量与常规气象数据进行处理与整编，最终形成涵盖半小时、日、月、年四种时间尺度的数据产品集。该数据集可应用于生态系统碳循环响应机制分析、气候变化背景下固碳效益评估等研究领域，同时可为生态系统模型参数优化与结果验证提供重要参考。通过多平台架构、多尺度融合与多方法耦合，本数据集有望为解析区域乃至全球生态系统碳-水-热循环机制、时空动态特征以及未来碳汇潜力预测提供基础支撑，进而为实现中国碳中和目标提供科学依据。
