摘　　要：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2018–2020年辽河三角洲稻田生态系统的通量观测数据,通量塔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)数据标准处理流程形成生态系统碳水通量和关键气象要素四种时间尺度数据集,包括半小时、日、月和年的数据文件。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 play an important role in the study of agricultural land use and global carbon cycle.As one of the main rice producing areas in Northeast China,the Liaohe River Delta provides a good experimental platform for the study of carbon and water cycle in Paddy fields.However,due to the insufficient study of long-term carbon and water fluxes in the paddy areas of the Liaohe River Delta,there is an urgent need of long-term data monitoring and sorting.This dataset collects the observations of the flux data of the paddy field ecosystem in the Liaohe River Delta from 2018 to 2020 from the Panjin Paddy Field Research Station of the Northeast Ecological and Agrometeorological Field Experimental Base of China Meteorological Administration.Based on the data processing system of the China Flux Observation and Research Network(ChinaFLUX),we prepared standardized data files for the dataset of water fluxes of ecosystem carbon and key meteorological elements,including data files at hourly,daily,monthly and yearly scales.This dataset is of great significance for the accurate evaluation of the position and role of carbon and water fluxes of paddy field ecosystems in the regional and global carbohydrate circle in the Liaohe River Delta.
