摘要:陆地生态系统碳水循环过程是全球生态系统中重要的生态学过程,科学定量森林生态系统的碳水循环过程中的碳水通量是准确定量陆地生态系统碳水过程的碳水过程的关键所在,基于微气象理论的涡度相关通量观测技术实现了对森林生态系统的碳水通量的准确定量,获取的碳水通量监测数据为研究森林生态系统碳“源汇”贡献提供了坚实基础。作为中国生态系统研究网络(Chinese Ecosystem Research Network,CERN)和国家野外科学观测研究站网络(National Ecosystem Research Network of China, CNERN)成员,鼎湖山森林生态系统定位研究站自2002年底始对我国南亚热带鼎湖山针阔叶混交林森林类型进行碳水通量监测,现已完善为系统规范化的监测。其中针阔叶混交林为鼎湖山主要森林类型,也是我国南亚热带常见森林类型。按照中国通量研究网络(ChinaFlux)的统一规范,在该森林类型已进行长达17年的生态系统水平碳水通量及关键气象要素标准化监测。本数据集通过整理和统计,列出了2003–2010年鼎湖山针阔叶混交林碳水通量的动态实测数据,并包含了相关的数据集构建过程信息。建立和共享本数据集可以为深入探讨全球水热格局变化情形下的生态系统与大气之间碳、水和能量交换监测研究提供本底资料,为该地区的森林经营管理及生态系统功能评价提供数据支撑。

Abstract: Carbon-water cycle process in terrestrial ecosystems is a critical ecological process in the global ecosystems, and the scientific quantitation of carbon water flux in the carbon-water cycle of forest ecosystem is a key to accurately quantify the carbon-water process in terrestrial ecosystems.The eddy covariance is a micro-meteorological method that is currently used to monitor carbon-water flux and to achieve an accurate quantification of these fluxes in forest ecosystems. The technique provides a solid foundation for the study of carbon source/sink contribution of forest ecosystems in carbon sequestration. As a core member of Chinese Ecosystem Research Network (CERN) and National Ecosystem Research Network of China (CNERN), Dinghushan Forest Ecosystem Research Station has monitored carbon and water flux in a mixed broadleaf-conifer forest being a major forest type in low subtropical China since the end of 2002, and now the monitoring work has been done towards an improved standardization procedure. Among the major forest types, the mixed broadleaf-conifer forest is a typical forest at Dinghushan, and it is also the common forest type in lower subtropical China. According to the unified technical specifications of ChinaFlux, a 17-year of standardized monitoring of carbon-water flux and key meteorological elements in the mixed coniferous broad-leaved forest ecosystem has been carried out at Dinghushan Forest Ecosystem Research Station. The datasets on the monitoring were systematized and analyzed statistically, and the dynamic measurement data of carbon water flux in the mixed coniferous broad-leaved forest from 2003 to 2010 at Dinghushan were presented. The datasets also included the information on the process of dataset construction. The setup and data sharing of the carbon-water flux database provide critical data for deep studies on the carbon, water and energy exchange between the forest canopy and atmospheric boundary layers, in the context of water and heat pattern under global change, whereas it is a strong support for forest management and ecosystem service function evaluation in this lower subtropical area.
