摘　　要：以2002-2003年福建省沿海11个城市的酸雨监测数据为基础,结合850 hPa高度上的风场资料,探讨各个沿海城市城郊两地酸雨的时空分布及差异.2002-2003年,福建省多数沿海城市城郊两地酸雨污染程度有一定差异,城区降水酸度主要由局地污染物的化学属性所决定,郊区酸雨污染则受外来污染物的影响;四季气象条件和850 hPa高空风向的变化都对沿海城市城郊两地酸雨污染产生一定程度的影响,并影响降水的酸性.The paper takes the acid rain monitoring data from 2002 to 2003 in both urban areas and suburbs of 11 coastal cities as a basis. In combination with related data on the wind field at 850 hPa, we discuss the spatiotemporal distribution of acid rain in urban areas and suburbs of various coastal cities. It proves that from 2002 to 2003 there was a certain difference in the extent of acid rain pollution between urban areas and suburbs of most coastal cities of Fujian Province. The acidity of urban precipitation depends on the chemical properties of pollutants in its local area, in contrast, the acid rain pollution in suburbs results from the influence of extraneous pollutants. In addition, the variation of meteorological conditions throughout the year and the wind shifts in the upper air at 850 hPa influence not only the acid rain pollution to a certain extent but also the acidity in precipitation in the suburb and the urban area of coastal cities.
