摘　　要：选择杭州3家疗养院绿地为研究对象,以绿化三维量为量化指标,通过研究绿化三维量和绿化层次数与空气负离子增加效益之间的相关关系,分析群落不同层次对负离子浓度的影响,进一步研究植物群落结构与负离子浓度的关系,为疗养院绿地规划提供科学依据。结果表明:空气负离子增加效益与绿化三维量呈极显著相关(p<0.01),回归方程决定系数(R2)在0.90左右,可以精确表达绿化三维量与负离子增加效益之间的相关关系,绿化层次数与负离子增加效益显著相关(p<0.05),回归方程决定系数(R2)在0.40左右,不能精确反映绿地水平与负离子浓度关系;乔木层和地被层绿化三维量与负离子增加效益均是显著相关,灌木层相关性不明显,负离子增加效益主要由乔木层和地被层产生。In order to provide scientific basis for the sanatorium green space design,effects of different plant community layers on aeroanions were examined by analyzing the relationship between three-dimensional green biomass（TGB） and increased efficiency of aeroanions（IEOA）.Most significant correlations were observed between TGB and IEOA.The coefficients of determination（R2） of the simulation equations established were around 0.90,indicating that the equations could accurately describe the relationship between TGB and IEOA.The number of greening layers was most significantly correlated to IEOA（p0.05）.However,simulation equations could not accurately describe the relationship,because the coefficients of determination（R2） was only about 0.40.Trees and groundcovers play major roles in the overall vegetation community to the contribution of IEOA.
