摘　　要：为了研究局地污染源对大连地区酸雨形成的影响,在市区及县级市布设监测点对酸雨进行监测,并获取酸雨点位附近局地污染源的酸性污染物排放量,应用地理信息系统的空间叠加分析功能,分析局地源对大连地区酸雨点位分布和频率变化的影响。结果表明:部分距离大污染源较近的点位受局地源影响较明显,但市区酸雨频率高低与局地源二氧化硫排放量变化趋势并不完全一致,说明大连地区酸雨的形成除了受本地源的影响外,还应存在其它更复杂的影响因素。In order to researchinfluence oflocal pollution sourcesforacid rainin Dalian, seven monitoring sites were set up to monitor acid rain frequency, and sulfur dioxide emissions from nearby pollutant sources were gotten from environmental statistic. Affection of local pollution sources on spatial pattern and frequency of acid rain was studied using GIS and GPS. The results showed that some monitoring sitescloser to large pollutant sources were affected by local pollution sources more obviously. However, in urban area, the trends of acid rain frequency and local pollution source emissions were not entirely consistent, which indicated that in addition to local pollution sources, the formation of acid rain in Dalian area was affected by also other more complex factors.
