| 摘 要： | 本文利用１９８８年至１９９２年兰州市１０月至下年度３月期间的较为详尽的污染资料，进行了统计平均，通过图的形式，总结了兰州市冬半年大气污染物分布特征及变化规律，并就这种特征和规律进行了分析，一年之中，ＳＯ２、ＣＯ、ＮＯｘ浓度最大值出现在１２月，而Ｏ３浓度则在此月最低。之内，ＣＯ、ＮＯｘ出现两次峰值，ＳＯ２最大值出现于午后，Ｏ３则较为复杂与ＮＯｘ牵扯相连，峰谷相映．ＳＯ２、ＣＯ、ＮＯｘ３种污染物的浓度城关区大于西固区，而Ｏ３则相反。

| Abstract: | The continent investigations of the air pollutants over the Lanzhou basin from the winter half year of 1988 to that of 1992 show that during the whole year, the maximal values of the concentrations of SO2, CO and NOx occur in December while O3 is minimal; during a day, the concentrations of CO and NOx have two peaks, SO2 reaches its peak immediately after the noon, and O3 is more complicated but closly related to NOx. The concentrations of SO2, CO and NOx pollutants in the city district are larger than in Xigu District, while O3 is just in the opposite case. |
