从宏观角度研究了山东省的区域性酸沉降，以代表性地区点（农村）布点为主，根据１９９２年７月至１９９３年６月监测资料，着重分析了湿沉降中的降水酸度时空分布规律，降水ＳＯ２－４浓度时空分布规律，降水主要化学成分和干沉降大气中ＳＯ２、ＮＯ２、ＴＳＰ时空分布规律，并从气象角度对酸雨成因机理作了初步分析。 From a macroscopic perspective, the regional acid deposition in Shandong Province was studied, mainly in the representative areas (rural areas). Based on the monitoring data from July 1992 to June 1993, the temporal and spatial distribution of precipitation acidity in wet deposition was analyzed emphatically , The spatiotemporal distribution of SO2-4 concentration in precipitation, the main chemical components of precipitation and the spatial and temporal distribution of SO2, NO2 and TSP in the dry depositional atmosphere. The mechanism of acid rain was also analyzed from the meteorological point of view.
