红河州人为源氨排放清单及分布特征

Anthropogenic Emission and Distribution of Ammonia in Honghe Prefecture

根据收集的红河州各类人为源氨排放活动水平数据和排放因子,建立了2017年红河州人为源氨分类别和县市排放清单。结果表明,2017年红河州人为氨源排放总量为93.21kt,其中农田生态系统、畜牧养殖业和其它源排放量分别为10.43kt、71.18kt和11.6kt,畜牧养殖业是红河州氨排放的主要来源,占排放总量的73.37%。弥勒市、建水县和泸西县是红河州氨排放量最大的3个县市,排放量为36.57kt,排放份额占红河州总排放量的39.23%,排放量最小的是河口县为0.85kt,仅占全州的0.91%。红河州的氨排放强度为3.0t/km^2·a^-1,泸西县是氨排放强度最大县市,高达6.8t/km^2·a^-1。

Based on the collected data of various anthropogenic ammonia emission activities and emission factors in Honghe Prefecture,the anthropogenic ammonia categories and the emission list of counties and cities in 2017 were established.The results showed that in 2017,the total amount of anthropogenic ammonia emission in Honghe was 93.21kt,including 10.43kt,71.18kt and 11.6kt from farmland ecosystem,animal husbandry,and other sources,respectively.Animal husbandry was the main source of ammonia emission,accounting for 73.37%of the total e-mission.Mile,Jianshui and Luxi are the three counties with the largest ammonia emissions in Honghe,with the e-missions of 36.57kt,accounting for 39.23%of the total emissions,and Hekou with the smallest emissions of 0.85kt,accounting for only 0.91%of the total emissions.The ammonia emission intensity of Honghe is 3.0t/km^2 a^-1.Luxi has the largest ammonia emission intensity of 6.8t/km^2 a^-1.
