2020–2021年北京燕山山地丘陵区典型生态系统碳水通量观测数据集

本数据集为2020–2021年北京燕山典型山地丘陵碳水通量和常规气象要素观测数据集。观测站点依托北京燕山地球关键带国家野外科学观测研究站，地处北京市怀柔区怀北镇雁栖湖北侧山地丘陵区，包含山地灌丛、乔灌混交林和人工针叶林三类生态系统。数据采集和处理过程严格遵循中国通量观测研究联盟（ChinaFLUX）生态系统碳水通量和气象数据质量控制和规范。
本数据集包含生态系统CO2通量、显热通量、潜热通量、空气/土壤温度、土壤湿度、降水、总辐射、净辐射和光合有效辐射等观测指标，形成了30分钟、日尺度、月尺度和年尺度4类数据产品，展示了燕山典型山地丘陵区的碳水通量本底特征，并可为三类生态系统间的比较研究提供支撑。

This dataset is an observation dataset of terrestrial carbon and water fluxes and conventional meteorological elements in typical mountainous and hilly areas of Yanshan, Beijing, during 2020–2021. The observation station is based on the Beijing Yanshan National Field Scientific Observation and Research Station for Earth's Critical Zone, located in the mountainous and hilly area on the northern shore of Yanqi Lake, Huaibei Town, Huairou District, Beijing, covering three types of ecosystems: mountainous shrubs, arbor-shrub mixed forests, and artificial coniferous forests. The data collection and processing procedures strictly follow the quality control and specifications for ecosystem carbon-water fluxes and meteorological data of the ChinaFLUX (China Flux Observation and Research Network).
This dataset includes observation indicators such as ecosystem CO2 flux, sensible heat flux, latent heat flux, air/soil temperature, soil moisture, precipitation, global solar radiation, net radiation, and photosynthetically active radiation. Four types of data products at 30-minute, daily, monthly, and annual scales are developed, which reveal the background characteristics of carbon and water fluxes in the typical mountainous and hilly areas of Yanshan, and provide support for comparative studies among the three ecosystems.
