| 摘 要： | 利用气象、土地利用等资料,采用统计方法,对河北省雾霾的特征及诱因进行了研究,结果发现:1)河北省多年平均雾霾日数分布情况呈由西南往西北逐步递减的趋势;各季节雾霾天能见度的空间分布不同,秋冬雾霾较为严重,自西南向东北呈递减的趋势,夏季自西南向东北呈递增的趋势,春季则自东南向西北呈递增的趋势。2)河北省近几十年来雾霾日数增加明显,增长斜率为0.45,但低能见度日数并不随雾霾日数增加而增加,主要是因为雾日数持续减少。3)河北省雾霾与国内生产总值(Gross Domestic Product,GDP)、能源消耗总量呈正比关系,而与机动车数量相关性不大。

| Abstract: | Based on meteorological data and land-use data,statistical research methods,the genesis of haze in Hebei Province,as well as the spatial distribution and variation of haze during 1980-2013 and its long-term trend,are analyzed in this paper.The statistical analysis results can be summarized as follows: (1)There is a gradual decreasing trend in the multi-year average number of haze days from the southwest to the northwest.It is more than 5 days in most areas south of the Great Wall in Hebei Province,and more than 10 days in the Taihang Mountain area and Piedmont Plain area,with a maximum of 30 days or more in Shijiazhuang,West Xingtai and North Handan.The spatial distribution of visibility on haze days depends on the season.Visibility is better on haze days in winter than in spring,summer and autumn,with a decreasing trend from high values in the southwest to low values in the northeast in summer,autumn and winter,while a distribution of low values in the southeast to high values in the northwest in spring. (2)In recent decades,the number of haze days has an increasing trend (slope:0.45),especially since 1981.Furthermore,for years after 2001,there is a brief decreasing trend after a rapid rise in the number of haze days in Hebei Province.However,the number of low-visibility days does not increase as the number of haze days increases,mainly due to the decrease in fog days. (3)The number of haze days and meteorological factors are significantly correlated.The contribution rate of humidity is higher than that of temperature,meaning we can reduce or control fog and haze by increasing the air humidity to a certain extent.With the economic growth in Hebei Province,the number of fog and haze days shows an increasing trend,and the visibility shows a decreasing trend.Haze days,visibility and GDP are significantly correlated.There is positive correlation between haze and GDP,population growth,and energy consumption,but negative correlation between visibility and GDP and energy consumption in Hebei.The increase in the number of motor vehicles affects the number of haze days in Hebei Province very weakly.Therefore,to alleviate haze in Hebei Province,effective methods include industrial restructuring,changing the traditional heating system,as well as adjusting the structure of the fuel. |
