摘要
采用英国国家氨减排措施评价系统(NARSES)模型,计算出我国种植业氮肥施用氨排放量,排放强度时空分布。结果表明,2001年我国种植业氮肥施用氨排放量为1.60×109kg,其中排放量最大的月份为8月,占全年的17%,排放强度最大的地区为广东、河北、山东、河南、江苏和福建。
The emission amount of NH3 and its spatial and temporal distribution of emission intensity from nitrogen fertilizer application in planting system in China were calculated by National Ammonia Reduction Strategy Evaluation System（NARSES）. The results showed that the emission amount of NH3 was 1.60 ×10^9 kg. The highest emission was in August, which accounting for 17 percent of the total emission amount in the whole year regions with highest NH3 emission intensities are Guangdong, Hebei, Shandong, Henan, Jiangsu and Fujian.
