| 摘要: |
| 利用北海市2002~2012年中NO2,SO2和PM10浓度的监测数据,分析城区大气污染物的月变化、季节变化、年变化、空间分布以及地区生产总值(GDP)增长对污染物浓度的影响。结果表明:北海城区大气环境质量整体状况较优,主要污染物NO2,SO2和PM10污染物浓度具有明显的时空变化,污染物在时间上呈冬高夏低的季节性变化,并受季风、降水湿沉降的影响明显;在空间上,污染物呈南高北低的区域性变化,市区及近郊高于远郊。污染物浓度和GDP增长关系明显,GDP增长幅度较污染物增长幅度大,两者之间存在着显著线性相关关系。北海市第一产业(农林牧渔业)和第三产业(服务业)对污染物排放量贡献大于第二产业(工业及建筑业)。 |

| Abstract: |
| The characteristic of mensual, trimestral and annual variation and spatial distribution of air pollution, and their relationship with the gross domestic product (GDP) were analyzed based on the concentration of NO2,SO2 and PM10 in Beihai city from 2002 to 2012. The results showed that temporal and spatial variances of pollutants were significant. The concentration of pollutants in urban were higher than that in rural area, and the concentration of pollutants in winter seemed significantly higher than that in summer. There were significant association between pollutants and GDP. The impact of GDP from primary and tertiary industry on the pollutants emission was higher than that from secondary industry. |
