摘要
农业是重要的碳排放源,中国西部地区作为我国重要的农业区,其区域分布范围广泛,农产品种类较多,评估农产品碳排放值及影响因素,将为地方政府制定区域可持续发展战略以及应对气候变化提供技术参考。文章在系统梳理国内外相关文献的基础上,对耕作方式、土壤水分、施肥对作物生产碳排放的影响,日粮精粗比、添加剂、外界温度对家畜甲烷排放的影响,以及西部农产品碳排放测定方法和碳排放值进行了归纳与总结;最后,提出了推动我国西部地区低碳农业发展的措施,旨在促进我国农业的持续健康发展。
Agriculture is an essential source of carbon emission.The western region of China is an important agricultural region in China.The distribution range of regions is wide and the variety of agricultural products is abundant.Therefore,the evaluation of agricultural carbon emission and influencing factors could provide technical references for local governments to promote regional sustainable development,safety the nation and address climate changes.In this paper,the related literatures both at home and abroad were summarized systematically.The influences of cultivation methods,soil moisture and fertilization on the agricultural carbon emission were analyzed.Additionally,the impacts of daily concentrate-to-forage ratio,additives and external temperature on carbon emission from livestock production were also summed up.Moreover,the determination methods of agricultural carbon emission and emission values were also generalized.Finally,the measures were proposed to promote the development of low-carbon agriculture in western China as well as the sustainable and healthy development of China's agriculture.
