农业碳足迹理论可以系统评价农业生产过程中人为因素引起的碳排放，是构建低碳农业的理论基础，对实现低碳农业具有重要的指导意义。为探明农业生产中的碳足迹，本文基于河北吴桥县农户生产调查数据，利用农业碳足迹理论及研究方法，评价了华北平原冬小麦-夏玉米两熟种植模式的碳足迹。

The theory on carbon footprint of agriculture can systematically evaluate the carbon emission caused by artificial factors, from agricultural production process, which is the theoretical basis for constructing low-carbon agriculture and has important guiding significance in realizing low-carbon agriculture. In order to get a clear understanding of carbon footprint in agricultural production, this paper, Based on the farmer＇ s production survey data from Wuqiao County of Hebei Province, we systematically evaluated the carbon footprint of winter wheat-summer maize cropping pattern by using agricultural carbon footprint theory. The results were as follows ： The carbon footprint of winter wheat-summer maize cropping pattern was 1 737.37± 337.02 kg Ce/hm2 · a, and the carbon cost of grain was 0.12 ± 0.03 kg Ce/kg ; the carbon footprint of winter wheat was 1101.31±251.91 kg Ce/hm： · a, and the carbon cost of wheat was 0. 16±0.04 kg Ce/kg; the carbon footprint of summer maize was 636.06 ± 163.90 kg Ce/hm2 · a, and the carbon cost of maize was. 0.08 ±0.02 kg Ce/kg. In the composition of carbon footprint of winter wheat-summer maize cropping pattern, 61.76% was chemical fertilizer; 25.03% electricity; 7.44% diesel;4.75% seed; 1.02% pesticides. The amount of nitrogenous fertilizer and electricity consumption was positively correlated with the carbon footprint and the scale of planting was negatively correlated with the carbon cost. Therefore, the construction of low-carbon agricultural cropping patterns with water-saving, fertilizer-saving and a large scale, is an important way to realize agricultural energy saving and emission reduction on North China Plain.
