摘　　要：以合肥市大蜀山森林公园3种典型植物群落的负离子时空分布为研究对象,利用空气离子评议系数(CI)对该区域春季的空气清洁度进行评价。结果表明,雪松群落白天的平均空气负离子浓度为1 100个/cm3,杨树群落为1 831个/cm3,竹林群落为1 498个/cm3。植物新叶量的多少是影响植物群落负离子产生能力的关键因素,杨树林在4月份新叶量最多,生理活性最旺盛,空气负离子产生能力最强;其次是竹林,雪松林最弱。根据空气评价系数,3种群落空气清洁度顺序为杨树林>竹林>雪松林。This paper studied the temporal and spatial distributions of negative air ion in three typical types of plant community at Dashushan National Forest Park in Hefei City, and evaluated the air cleanliness of the region in spring by using the air ion assessment index （CI） . The results showed that on average in the daytime, the negative air ions concentration at Cedrus, poplar and bamboo communities were 1100, 1831 and 1498/cm3, respectively. The new leave amount significantly affected the ability of a plant community to produce negative ions. Poplar had the largest a- mount of new leave in April due to a vigorous physical activity, and thus it had the strongest ability to produce nega- tive air ions. Bamboo followed poplar, and pine produced the least anions. Based on the air evaluating coefficient, the air cleanliness index of the three plant communities followed as： poplar 〉 bamboo 〉 Cedrus.
