盘锦稻田碳水通量2018-2020年数据集

稻田在农业土地利用和全球碳循环研究方面具有重要意义。辽河三角洲是东北水稻主产区之一，为研究稻田碳水循环提供了良好的实验平台。但辽河三角洲稻区长期碳水通量的研究还比较欠缺，迫切需要对其进行长期的数据监测及整理。本数据集为辽河三角洲稻田生态系统2018–2020 年通量观测数据，数据采集地位于中国气象局东北地区生态与农业气象野外科学试验基地盘锦稻田研究站。基于中国通量观测研究网络（ChinaFLUX）数据处理体系形成了标准化的生态系统碳水通量和关键气象要素数据集，数据集包括半小时、日、月和年四种尺度的数据文件。本数据集对准确评价辽河三角洲稻田生态系统碳水通量在区域和全球碳水循环中的地位和作用具有重要意义。

Paddy fields hold significant importance in agricultural land use research and global carbon cycle studies. The Liaohe Delta is one of the major rice-producing regions in Northeast China, providing an excellent experimental platform for investigating the carbon-water cycle of paddy fields. However, long-term research on carbon-water fluxes in the paddy fields of the Liaohe Delta remains relatively limited, and long-term data monitoring and collation are urgently needed.

This dataset comprises flux observation data of the paddy field ecosystem in the Liaohe Delta from 2018 to 2020. The data were collected at the Panjin Paddy Field Research Station under the Ecological and Agricultural Meteorology Field Scientific Experiment Base of the China Meteorological Administration in Northeast China.

Based on the data processing framework of the China FLUX Observation and Research Network (ChinaFLUX), a standardized dataset of ecosystem carbon-water fluxes and key meteorological factors has been established. This dataset includes data files at four temporal scales: half-hourly, daily, monthly, and annual.

This dataset is of great significance for accurately evaluating the status and role of the carbon-water fluxes of the paddy field ecosystem in the Liaohe Delta in regional and global carbon-water cycles.
