2005-2014年锦州春玉米农田生态系统碳水通量观测数据集

A dataset of carbon and water flux observations in the agricultural ecosystem of spring maize in Jinzhou(2005-2014)

基于涡度相关方法的长期连续农田生态系统碳水通量观测,对于提高作物产量和水资源利用效率、促进双碳目标的实现具有积极意义。锦州农田生态系统野外观测站(锦州站)是中国通量观测研究网络(ChinaFLUX)成员站之一,位于辽宁省锦州市,地处我国春玉米主要产区。锦州站自2004年5月开始基于涡度相关方法对春玉米农田生态系统碳水通量进行综合观测,持续至今。遵循ChinaFLUX通量数据处理体系,本数据集整理和统计了2005–2014年锦州春雨米农田生态系统碳水通量和辅助气象环境观测数据,形成了30分钟、日、月和年4个时间尺度的标准化数据集,可为气候变化和农田生态系统碳水循环过程及其机理等研究提供数据支持。

The observation of carbon and water fluxes in agricultural ecosystems based on eddy covariance technique(EC)is of great significance for improving crop yield and utilization efficiency of water resources in cropland,and promoting the realization of carbon peaking and carbon neutrality goals.Jinzhou agricultural Ecosystem Field Observation Station(Jinzhou Station)is one of the member stations of Chinese FLUX Observation and Research Network(ChinaFLUX).It is located in the main spring maize-producing area in Jinzhou City,Liaoning Province,China.Jinzhou Station has been carrying out the EC-based observation of carbon and water fluxes of the spring maize agricultural ecosystem since May 2004.In line with the ChinaFLUX data processing protocols,we statistically collected the carbon and water fluxes and auxiliary meteorological environment observations of the spring maize agricultural ecosystem in Jinzhou from 2005 to 2014,so as to obtain a standardized dataset with four-time scales(i.e.half-hourly,daily,monthly,and yearly).This dataset is expected to provide data support for the study of climate change and the process and mechanism of carbon and water cycle in farmland ecosystems.
