A dataset of the observations of carbon and water fluxes in the paddy fields of Panjin (2018–2020)

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, Liaohe River Delta provides a good experimental platform for the study of carbon and water cycle in Paddy fields. However, the study of long-term carbon and water fluxes in the Liaohe River Delta Paddy area is still insufficient, and long-term data monitoring and sorting are urgently needed.This dataset is the flux data of the paddy field ecosystem in the Liaohe River Delta from 2018 to 2020, collected 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), standardized datasets of water fluxes of ecosystem carbon and key meteorological elements are established, including data files collected at half an hour, day, month and year scales. This dataset is of great significance to accurately evaluate 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.This dataset is of great significance for accurately evaluating the status and role of carbon and water fluxes in the rice field ecosystem of the Liaohe Delta in the regional and global carbon and water cycles.
