In order to study the relationship between tri-dimensional green biomass (TGB) and the nero-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 neroanion 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 (p＜0.01),the person correlations coefficients was about 0.90,while non-linear fitting value Adj·R2 was above 0.91,with higher precision.
