金昌市大气环境中SO_2变化规律分析及对策研究

通过1996~2005年金昌市大气环境监测资料的分析,对金昌市大气环境中主要的污染物质二氧化硫的时间及空间浓度变化规律、影响因素及主要监测点监测数据进行了研究,研究发现,市区二氧化硫污染物浓度随时间变化呈现明显的规律,空间分布特征明显。从工业二氧化硫排放量、风向与风速、城市功能区布局等方面分析成因后,提出了相应的防治对策。

Study on Variation Pattern of SO2 in Jinchang and Its Countermeasures

Based on the study on the information during the period from 1996 to 2005 of the air environment in Jinchang,this research first makes a careful examination of sulfur dioxide,the major pollutant in this city,on the following aspects: the temporal and spatial variation pattern of its concentration,the contributing factors and important data acquired from some monitoring sites.Then,it is advanced that the air concentration of sulfur dioxide shows an evidently relevant change pattern according to the temporal variation and demonstrates explicit spatial characteristics.The quantity of industrial emissions of sulfur dioxide,the direction and speed of the wind and the distribution of urban zoning are analyzed.Some practical and efficacious countermeasures are put forward.
