摘　　要：选择吉林市江南公园内具有代表性的绿地结构为研究对象,对不同绿地结构的空气负离子水平进行测定。结果表明,不同绿地结构空气负离子浓度差异极显著(P<0.01),其中,乔祼型绿地空气负离子浓度最高,在观测期间内空气清洁度最高,每天均达到A级,空旷地空气清洁度较低,无A级。不同绿地结构空气负离子浓度、空气清洁度高低排序为:乔祼型>乔灌草型>乔草型>疏林草地型>空旷地。The representative greenbelt structure in Jilin Jiangnan Park was selected to determine the effect of different greenbelt structures on the air negative ions concentration.As indicated by the results,the air negative ions concentration varied largely with different greenbelt structures（P0.01）.The air negative ions concentration of arbor greenbelt was the highest and the air cleanness level during the determination days all reached A level,while the air cleanliness of bare land was the lowest without A level.The air negative ions concentration and air cleanliness level of different greenbelt structures were shown as arbor land arbor-shrub-grass arbor-grass open forest and grassland bare land.

关 键 词：绿地结构 空气负离子水平 空气清洁度
