摘　　要：自涡度相关技术被广泛应用以来,对于生态系统碳源汇功能的估算研究日趋完善。燕山区域作为北京最为重要的生态屏障与碳汇功能区,对其碳水通量的研究目前相对较少,特别是聚焦区域代表性生态系统类型如山地灌丛。本数据集为2020至2021年北京市怀柔区燕山山地灌丛、乔灌混交林和人工针叶林三类生态系统碳水通量观测数据。数据采集和处理过程严格遵循中国通量观测研究联盟(China FLUX)生态系统碳水通量和气象数据质量控制和规范。本数据集预期可以为分析我国华北典型山地丘陵区对全球变化的响应及其机制提供支撑。The extensive application of eddy covariance technology in studying water and carbon fluxes has largely enhanced our understanding of carbon sinks and sources in terrestrial ecosystems.However,the carbon dynamics of Yanshan Mountain(a crucial ecological barrier for Beijing)stills remain unclear,especially in relation to regional representative ecosystem types such as shrub ecosystems.This dataset is the flux data from the Yanshan hilly regions in Huairou District,Beijing from 2020 to 2021,covering three ecosystems—montane shrubland,arbor-shrub mixed forest and coniferous forest.This dataset is generated and analyzed in strict compliance with the China FLUX standards of ecosystem carbon water flux and meteorological data.It can provides valuable insights for studying the typical mountainous and hilly areas in North China as well as its mechanism and response to the global change.
