2018-2020年盘锦芦苇湿地碳水通量数据集

An dataset of carbon and water fluxes over the reed wetlands in Panjin City(2018-2020)

湿地拥有巨大的碳汇能力、活跃的水汽交换和热量调节能力,是稳定温室气体排放、减缓气候变化的关键生态系统。辽河三角洲湿地是亚洲最大的暖温带滨海湿地,但湿地长期碳水通量的研究还比较欠缺,影响该地区CO_(2)通量和区域碳汇模拟精度,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芦苇湿地生态系统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芦苇湿地研究站。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4种尺度的数据文件。本数据集对准确评价辽河三角洲芦苇湿地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。

With significant carbon sink capacity,active water vapor exchange and heat regulation capacity,wetlands are key ecosystems for stabilizing greenhouse gas emissions and mitigating climate change.Despite Liaohe Delta wetland being the largest warm temperate coastal wetland in Asia,its long-term carbon and water fluxes of the wetland are still not thoroughly examined,which limits the accuracy of simulating CO_(2) fluxes and regional carbon sinks.As a result,it is urgent to carry out long-term data monitoring and sorting in this area.This dataset is the flux data of the reed wetland ecosystem in Liaohe Delta from 2018 to 2020,collected from the Panjin Reed Wetland Research Station of the Northeast Ecological and Agrometeorological Field Experimental Base of China Meteorological Administration.Based on the data processing system of China Flux Observation and Research Network(ChinaFLUX),we established the standardized dataset of ecosystem carbon and key meteorological elements,including data files at half-hourly,daily,monthly and yearly scales.This dataset is of great significance in accurately evaluating the status and roles of carbon and water fluxes in the reed wetland ecosystem of Liaohe Delta in the regional and global carbon and water cycles.
