摘要

文章基于新疆昌吉州牛粪管理方式微观调研数据,采用IPCC(2006)推荐的畜禽粪便温室气体排放估算方法,对牛粪管理方式改进前后CH_4和N_2O的综合排放因子进行测算。结果表明,在原有养殖规模不变的条件下,改进牛粪管理方式后,甲烷综合排放因子由17.13降为8.86,二氧化氮综合排放因子由0.99降为0.46,总体达到596.67万吨二氧化碳当量的减排潜力。要综合考虑养殖规模、养殖户经济能力、政府环评规制及地形、气候等自然条件因素改进牛粪管理方式,采取差异化减排策略,建议山区散养以草地自然消解为主,平原大中规模养殖户加强沼气工程管建,小规模养殖户规范牛粪堆肥操作,以期达到较好的减排效果。
        Based on the micro-survey data of cattle manure management in Changji of Xinjiang, the comprehensive emission factor of CH_4 and N_2 O is measured before and after improving the management of cow manure in this article with estimation method of greenhouse gas emissions from livestock manure recommended by IPCC(2006). The results showed that the comprehensive emission factor of methane was reduced from 17.13 to 8.86, and the comprehensive emission factor of nitrogen dioxide was reduced from 0.99 to 0.46 after improving the management of cow dung when the original culture scale was unchanged, and emission reduction potential of 5.967 million t CO_2 equivalent was obtained overall. It is necessary to adopt differentiated emission reduction strategies comprehensively considering the scale of cattle breeding, the economic capacity of cattle farmers, government environmental assessment rules and the natural conditions such as terrain and climate to improve the management of cow dung. It is suggested that cattle manure in free-range of mountainous areas should be decomposed naturally by grassland, large and medium-sized cattle farmers in the plains should strengthen the construction and management of methane project, and small-scale cattle farmers should regulate the operation of composting of cattle dung aiming to achieve better emission reduction effects.
