摘　　要：涡度相关技术(EC)是目前唯一可以在生态系统尺度直接观测植被与大气间二氧化碳和水汽通量的技术,在解析陆地生态系统碳、氮、水循环过程的动态变化及其对环境变化的响应与控制机理等方面得到了广泛应用。如何准确探知中国人工林在全球森林碳循环及全球气候变化过程中的重要作用,亟需采用先进技术开展精确观测和长期研究。江西千烟洲红壤丘陵地球关键带国家野外科学观测研究站(简称千烟洲站)是国内较早采用涡度相关技术开展人工林碳水通量观测和研究的野外站点之一,持续获取并积累了一批长期观测数据。在前期发布数据的基础上,通过标准化整编,再次发布2011-2015年生态系统碳水通量和气象数据,以充分发挥这些数据的科研价值,进一步支撑国家及区域的碳汇评估,并推动相关科学研究的发展。本次发布的数据集主要包括生态系统CO_(2)/H_(2)O通量、潜热和显热通量,以及空气温湿度、净辐射、光合有效辐射和土壤温湿度等观测内容,并通过标准化处理和加工分别形成半小时、日、月和年尺度等数据。Eddy covariance(EC)technique is the only method to measure the gas exchange between ecosystem and atmosphere directly at ecosystem scale.It has been widely used in analyzing the dynamic changes of carbon,nitrogen and water cycles in terrestrial ecosystems and their response and control mechanisms to environmental changes.To better understand the role of China’s plantations in global carbon sequestration across the world,it is essential to establish more eddy covariance observation systems and conduct long-term studies.As a pioneering station using eddy covariance technique in China,the National Field Scientific Observation and Research Station of Qianyanzhou Red Soil Hilly Region(Qianyezhou Station)has continuously monitored carbon and water exchanges in the pine plantations for more than 22 years,and has acquired and accumulated a batch of long-term observation data.Based on previously published data,we released the carbon,water and heat fluxes and meteorological data from 2011 to 2015 following standardized compilation,so as to fully leverage the scientific value of the data,further support the efforts in national and regional carbon sink assessments,and advance relevant scientific research initiatives.This dataset primarily includes observations of CO_(2)/H_(2)O flux,latent and sensible heat flux,along with measurements of air temperature and humidity,net radiation,photosynthetically active radiation,as well as soil temperature and moisture.The dataset has been processed to provide standardized data on half-hourly,daily,monthly,and annual scales.
