基于水-碳足迹的水资源环境经济效益优化研究

Optimization of Environmental Economic Benefits of Water Resources Based on Water-Carbon Footprint

以我国主要粮食生产基地之一的河北省为例,选取6类主要农作物进行水-碳足迹核算,并在水-碳足迹空间分布特征基础上,设计一种农业水资源优化模型。结果表明,农业总经济贸易收入增加10%、农业生产碳足迹减少1%、农业低碳竞争力提升4%。通过基于水-碳足迹的农业水资源优化模型,能有效促进农业经济的增长、提升水资源的分配管理效率,并减少农业生产的碳排放,对于推动农业的绿色发展具有重要意义。

In this study,Hebei province,one of the main grain production bases in China,was selected for water-carbon footprint calculation of six main crops,and an optimization model of agricultural water resources was designed based on the spatial distribution characteristics of water-carbon footprint.The experimental results show that the total economic and trade income of agriculture has increased by 10%,the carbon footprint of agricultural production has decreased by 1%,and the low-carbon competitiveness of agriculture has increased by 4%.The agricultural water resources optimization model based on water-carbon footprint can effectively promote the growth of agricultural economy,improve the efficiency of water resources allocation and management,and reduce the carbon emission of agricultural production,which has important practical significance for promoting the green development of agriculture.
