摘　　要：选择杭州市3家疗养院,在植物调查的基础上,筛选出36个样地,观测空气负离子浓度,以绿化三维量为量化指标,通过对绿化三维量和空气负离子浓度相关性检验和非线性拟合,研究绿化三维量与负离子浓度之间的相关关系,探讨一定范围内植物绿化三维量的合理指标,以期为疗养院绿地规划及康复保健活动的开展提供科学依据。结果显示:乔木层绿化三维量占总量的近90%;3家疗养院绿地空气负离子浓度在600～1 200个.m3之间,空气清洁度最低为C级,高于允许值;空气负离子浓度与绿化三维量Person相关系数在0.94左右,呈极显著正相关(p<0.01),非线性拟合精度较高(Adj.R2=0.91),并据此提出在20 m×20 m绿地范围内植物绿化三维量的合理值。In order to study the relationship between tri-dimensional green biomass（TGB） and the aero-anion concentration,the TGB was investigated,the air negative ions concentrations of 36 samples（20 m × 20 m） in 3 sanatoriums in Hangzhou were observed.Through examining the associativity and fitting a non-linear curve between tridimensional green biomass and air negative ions in sanatorium,the correlations between tridimensional green biomass and air negative ions were studied.The results show that the arborous layer’s TGB which determined the TGB level of the entire green space vegetation nearly taken up 90 percent of the total TGB;the aeroanion concentration in the three sanatoriums ranked from 600 to 1200 tree m-2,the air cleanliness reached or exceeded the grade C which is higher than the allowable value of aero-anion concentration;there was a Highly significant positive correlation between tridimensional green biomass and air negative ions in sanatorium（p0.01）,the person correlations coefficients was about 0.90,while non-linear fitting value Adj.R2was above 0.91,with higher precision.
