2014-2018年呼中北方林森林生态系统碳水通量观测数据集

A dataset of carbon and water fluxes of the boreal forest ecosystem in Huzhong(2014-2018)

北方林在全球碳库中占有重要份额,且对气候变暖的响应极为敏感,在气候变化和碳循环研究中备受关注。中国北方林森林生态系统定位研究站(呼中站),位于我国最大的寒温带针叶林生态系统自然保护区内,是中国通量观测研究网络(ChinaFLUX)成员站之一,自2006年起开展基于涡度相关技术的碳水通量观测。遵循ChinaFLUX通量数据处理体系,本数据集整理和统计了2014–2018年呼中站北方林森林生态系统碳水通量和辅助气象环境观测数据,数据产品分为30分钟、日、月和年4个时间尺度,可为气候变化和北方林森林生态系统至区域碳、水、能量平衡的研究提供数据支持。

As an important component of the global carbon pool,boreal forests have attracted much attention in the research on climate change and carbon cycle due to their extreme sensitivity to climate warming.Located in the largest cold-temperate coniferous forest ecosystem nature reserve in China,China Boreal Forest Ecosystem Research Station(Huzhong Station)is one of the member stations of Chinese FLUX Observation and Research Network(ChinaFLUX),which has conducted long-term carbon and water flux observations of boreal forest ecosystems based on eddy covariance techniques since 2006.Following the ChinaFLUX data processing protocols,we collected the carbon and water fluxes and auxiliary meteorological environment observations of the boreal forest ecosystem at Huzhong Station from 2014 to 2018.Processing the data in a standard process,we formed a standardized dataset with four time scales,namely half-hourly,daily,monthly and yearly.The dataset is expected to provide data support for the studies on climate change,boreal forest ecosystem carbon,as well as water and energy balance.
