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类产品，展示了燕山典型山地丘陵区的碳水通量本底特征，可为三类生态系统间的比较研究提供支撑，并可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。

This dataset presents observations of carbon-water fluxes and conventional meteorological elements in typical mountainous and hilly areas of the Yanshan Mountains, Beijing, during 2020–2021. The observation station is affiliated with the Beijing Yanshan National Field Scientific Observation and Research Station for Earth Critical Zone, situated in the mountainous and hilly region north of Yanqi Lake, Huaibei Town, Huairou District, Beijing, and encompasses three types of ecosystems: mountainous shrubs, arbor-shrub mixed forests, and planted coniferous forests. The dataset includes observation metrics 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 product series at 30-minute, daily, monthly, and annual temporal scales are generated. This dataset showcases the baseline characteristics of carbon-water fluxes in typical mountainous and hilly areas of the Yanshan Mountains, providing support for comparative research among the three ecosystems, as well as for analyzing the responses of typical mountainous and hilly regions in North China to global changes and their underlying mechanisms.
