| 摘 要： | 根据长沙地区1970—2012年气象观测资料及环境监测数据,对近43年长沙雾霾特征及影响因子进行了分析。结果表明,长沙地区雾的年际变化具有显著的倒"U"型特征,霾整体上呈上升趋势;雾霾天气主要集中在秋冬季节,春夏季节较少;从空间分布来看,望城区(县)和宁乡县雾霾天气最多,浏阳市次之,长沙市区最少。在一次持续性雾霾天气过程中(10.2~10.12),相对湿度、PM2.5质量浓度与能见度呈现显著负相关,说明PM2.5质量浓度和相对湿度是雾霾天气形成的首要影响因子。

| Abstract: | Based on meteorological observation data and environmental monitoring data of Changsha in the period from 1970 to 2012, we analyzed the characteristics and influencing factors of the fog/haze in Changsha. The results show that fog had obvious inverted "U" characteristic, haze is on the rise as a whole, and the fog/haze mainly concentrates in autumn and winter.From the view of spatial distribution, fog /haze had serious influence to Wangcheng County and Ningxiang County, but had the least influence to Urban District of Changsha. During the occurrence of the fog/haze, the relative humidity and the concentration of PM2.5 were significantly negatively correlated with visibility. Therefore, these factors are the main influencing factors of fog/haze. |
