摘要
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(YCES)is located in the lower Yellow River irrigation district,where the double cropping system of winter wheat and summer maize is the dominant pattern.YCES is one of the oldest flux stations in China.This dataset collects the observed ecosystem carbon and water flux data from 2003 to 2010 in YCES.A standardized dataset of ecosystem carbon water fluxes and key meteorological elements were processed based on the data processing system of ChinaFLUX.This dataset is of great significance for studying important parameters such as farmland productivity and water consumption in North China,as well as for accurately evaluating the status and role of carbon-water fluxes of the farmland system of winter wheat and summer maize in the regional carbon-water cycle.
