摘    要:根据收集到的城市尺度排放源活动水平数据,采用排放因子法,基于"自上而下"和"自下而上"相结合的方式建立了河南省2013年大气氨排放清单,利用GIS技术进行3 km×3 km空间网格分配.结果表明,河南省2013年大气氨排放总量为1035.3 kt,排放强度为6.4 t ·km-2;畜禽养殖和氮肥施用为主要氨排放源,分别占总排放量的52.71%和31.53%;畜禽养殖中肉牛、蛋禽和山羊为主要贡献源,分别占畜禽养殖排放总量的34.98%、16.63%和14.02%;不同城市排放源构成和排放强度不同;南阳市、周口市、商丘市和驻马店市是排放量较大的地级市,分别占全省总量的11.53%、9.84%、9.62%和9.57%;濮阳市和漯河市排放强度最大,分别达到10.7 t ·km-2和10.2 t ·km-2;空间分布特征显示,中东部地区排放量较高,西部地区相对较低,排放量较大的地区集中在平原地区和人口密集区域.

关 键 词:  畜禽养殖  氮肥施用  排放强度  网格化

Abstract:Based on the best available activity data at a city level from top down and bottom up methods, a 2013-based emission inventory of NH3 was established for the Henan Province using an emission factors method. The 3 km×3 km spatial gridded distribution was carried out by using GIS technology. The results showed that the total amount of atmospheric NH3 emission in Henan Province in 2013 was 1035.3 kt, and the average emission intensity reached levels of 6.4 t/km2. Livestock and nitrogen fertilizer applications were the top two emission sources, accounting for 52.71% and 31.53% of the total emissions, respectively. Beef, laying hen, and goats were the main contributors in the livestock category, accounting for 34.98%, 16.63%, and 14.02% of the total emissions, respectively. There were different characteristics between emission source contributions and emission intensities in each city. Nanyang, Zhoukou, Shangqiu, and Zhumadian were the prefecture-level cities with large emissions, accounting for 11.53%, 9.84%, 9.62%, and 9.57% of the total amount in Henan Province, respectively. The NH3 emission intensities of Puyang and Louhe were larger than those of other cities, reaching up to 10.7 t·km-2 and 10.2 t·km-2, respectively. The spatial distribution revealed that emissions in the middle eastern region were relatively higher; whereas, the western region emissions were relatively low. The areas with high emissions were concentrated in the plains and densely populated areas.
Keywords:ammonia  livestock  nitrogen application  emission intensity  gridded allocation
