深圳市霾日分布特征与城市经济指标关系

Relations between the Haze Distribution and the Urban Economic Indicators in Shenzhen City

利用深圳市近30a来霾日UV法统计数据进行霾日分布特征分析,并结合1980～2007年深圳逐年国民经济指标统计数据,着重讨论了深圳市霾日与城市经济指标的相关性。研究表明,90、00年代的初期至中期,是深圳霾日增长趋势最明显的两个阶段,月均霾日高值在12月至次年1月,达8d/月以上;低值在6～7月,达2d/月以下,随年代推进,各月霾日整体呈增加趋势,但高低值分布并未发生明显变化。深圳霾日与本地建筑业、住宿和餐饮业、批发和零售业、工业、交通运输仓储和邮政业、渔业、金融业经济指标呈高度相关或显著性相关,这些部门活动很可能是导致灰霾产生的气溶胶污染的主要来源,其中以建筑源污染为首。

Basing the statistics data of haze days of Shenzhen in recent 30 years and using UV method the distributions of haze days were analyzed.Combined with the annual statistical data of the national economy indicators from 1980 to 2007,the relations between the haze days and urban economic indexes were focused.The results are as follows：during the early to mid time in the 90＇s and 00＇s,the rapid growth of the haze days are the most significant,with the high（low）value of the average monthly haze days from December to next January,of 8d/month or more（from June to July,of 2d/month or less）.The overall trend of haze days each month is increasing year by year,without the distribution of high and low values changing significantly.The haze days are highly correlated with the economic indicators of local construction industry,hotels and catering,wholesale and retail,industrial,transportation,warehousing,postal industries,fisheries and finances.Activities in these sectors are likely the major source of aerosol pollution to haze and the construction pollution is most significant.
