| 通过对比分析发现，2007年客观源清单比2001年初始源清单能够更好地反映当前长江三角洲地区的大气污染物源排放情况。基于客观源清单，利用第三代空气质量模式（Models-3/CMAQ）较好地模拟出长三角地区近地层大气浓度的日变化和空间分布，模拟结果表明，NOX与O3在空间分布上并不一致，两者之间存在非线性关系，NO2与SO2之间存在较好的线性变化相关性。 |

| Abstract: |
| The present emission condition of air pollution sources in the Yangtze river delta region could be reflected more comprehensively through the objective source lists of 2007 than the initial source lists of 2001, according to the comparative analysis. Based on the objective source lists, the daily variation and spatial distribution of the stratigraphic air concentration of the Yangtze river delta region could be simulated via the Models-3/CMAQ, the results of which shows that the spatial distributions of NOX and O3 disaccord, there is a nonlinear relation between which. However, a better linear variation correlation exists between NO3 and SO3. |
