摘　　要：为了分析2000—2011年秦皇岛市畜禽温室气体排放的时空变化,研究根据省级温室气体清单编制指南,采用排放因子法,对秦皇岛市畜禽温室气体排放进行了估算。结果表明:秦皇岛市畜禽温室气体排放量自2000年的27.4 Gg CO2-eq增长到2011年的34.1 Gg CO2-eq,整体呈较平稳的增长趋势。在三类温室气体中,畜禽肠道发酵甲烷排放量所占比例最大,平均值为25.4 Gg CO2-eq;牛排放贡献率最大,占排放总量的62.4%。畜禽粪便管理甲烷排放量和畜禽粪便管理氧化亚氮排放量平均值分别为4.9 Gg CO2-eq和0.7 Gg CO2-eq;猪排放贡献率最大,分别占排放总量的76.7%和39.6%。秦皇岛市畜禽温室气体排放在空间分布上呈现较为明显的集聚特征,主要集中在昌黎县、抚宁县和卢龙县。To analyze the spatiotemporal changes in the greenhouse gas emissions from livestock and poultry in Qinhuangdao from 2000 to 2011, the emission factor method was used to estimate the greenhouse gas emissions from livestock and poultry in Qinhuangdao according to the guide- lines of provincial greenhouse gas list. The results showed that the total greenhouse gas emissions from livestock and poultry in Qinhuangdao ex- hibited a stable growth trend, increasing from 27.4 GgCO2 -eq to 34.1 GgCO2 -eq since 2000 to 2011. Methane emissions from enteric fer- mentation of livestock and poultry accounted for the largest proportion in the three types of greenhouse gases, with an average of 25.4 GgCO2 - eq; the enteric fermentation of cattle had the largest contribution rate to methane emission, accounting for 62.4% of the total methane emission from the livestock and poultry. The averages of methane and nitrous oxide emissions and from livestock and poultry manure managemen were 4.9 GgCO2 - eq and O. 7 GgCO2 - eq, respectively ; the enteric fermentation of pig had the largest contribution rate, accounting for 76.7 % and 39.6 % of the total methane and nitrous oxide emissions from the manure management. The greenhouse gas emissions presented obvious agglom- eration characterstics on the spatial distribution in Qinhuangdao, which concentrated in Changli county, Furring county and Lulong county.
