【摘要】 利用 2 0 0 1年 8月 1日至 2 0 0 2年 7月 31日的气象资料和逐时污染物浓度数据 ,分析福州市污染物的时空分布特征 ,气象条件和非气象条件对污染物浓度的影响。结果表明 :福州市的空气质量较好 ,夏半年空气质量优于冬半年。各污染物的日变化有明显的变化规律。污染物的浓度变化与空气污染气象条件的优劣密切相关 ,各气象要素对大气污染物有一定的制约关系 ,但并非简单的线性关系。人类活动对污染物浓度的变化影响较大更多还原

【Abstract】 Using meteorological data and horal pollutant concentrations data from 1 August 2001 to 31 July 2002, the temporal and spatial distribution characteristics of air pollutant concentrations and the influence of meteorological and non meteorological conditions on pollutant concentrations are analyzed. The results indicate that the air quality in Fuzhou is good, better in the summer half year than in the winter half year. The daily variations of air pollutants are obvious. The variations of air pollutant concentrations are correlated with meteorological conditions. Various meteorological factors affect air pollutant concentrations, but the linear correlation is not obvious. The human activity is one of main influencing mechanisms on the air pollutant concentrations.更多还原
