2003-2010年禹城冬小麦夏玉米农田生态系统碳水通量观测数据集

中国科学院禹城综合试验站（简称禹城站）地处黄河下游灌区，是华北平原冬小麦夏玉米复种灌溉农田的典型代表。禹城站是中国最早开展碳水通量长期观测的农田站之一。本数据集为禹城站冬小麦夏玉米农田生态系统2003–2010年通量观测数据，基于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。本数据集对研究华北农田生产力、耗水量等重要参数，以及准确评价华北冬小麦夏玉米农田生态系统碳水通量在区域碳水循环中的地位和作用具有重要意义。

Yucheng Comprehensive Experimental Station of the Chinese Academy of Sciences (hereinafter referred to as Yucheng Station) is situated in the irrigation region of the lower Yellow River, serving as a typical representative of double-cropping irrigated farmland (winter wheat-summer maize rotation) in the North China Plain. Yucheng Station is among the earliest farmland stations in China to conduct long-term observations of carbon and water fluxes. This dataset encompasses flux observation data of the winter wheat-summer maize farmland ecosystem at Yucheng Station spanning from 2003 to 2010. A standardized dataset of ecosystem carbon and water fluxes and key meteorological variables has been developed based on the ChinaFLUX data processing framework. This dataset holds significant importance for researching key parameters such as farmland productivity and water consumption in North China, as well as accurately assessing the status and role of carbon and water fluxes of the North China winter wheat-summer maize farmland ecosystem in the regional carbon-water cycle.
