摘要
采用统计数据结合物料衡算对重庆市主城NOx排放进行研究,结果表明:2004年主城各类点源、线源和面源共排放NOx 10.82万t,其中点源排放占总量的36.6%;线源排放占总量的38.2%;面源排放占总量的25.2%,ADMS-Urban大气模型运算结果显示:对主城环境空气NO_2浓度的分担率,点源占16.9%、线源占49.0%、面源占34.1%.
The NOx emission study system adopted in this study was based on statistical data, materiel balances and model calculation. The result showed that total emission of NOx was 19.21 × 10^4 t/a in 2004. The share rate of the gross quantity of NOx was 36.6 %, 38. 2 % and 25.2 % for stationary, linear and area sources, respectively. Calculation based on ADMS-Urban model showed that the share rate of NO2 concentration in the urban zone of Chongqing was 16.9%, 49.0% and 34.1 % for the stationary, linear and area sources, respectively.
