Plant community is the basic unit of green space, and provides the foundation ecological functionof green space. However, few researchers focus on plant communities of sanatorium and healing gardencurrently. In this study, based on the collection of information, combined with the site investigation,author surveyed Tridimensional Green Biomass of Wuyunshan Wanatorium, Qianjiang sanatorium(Shanghai Railway Bureau), Hangzhou Sanatorium plant communities, to pursue a method ofmeasuring and distribution the TGB of artificial greenbelt in small area. While TGB as a indicators, airions, temperature, humidity, inhalable particulate (PM10) were meaeured to quantitatively study therelationship between TGB and ecological indicators, as well as hoping to more accurately reflect therelationship between green space system and its ecological service functions more effectively and guidethe rehabilitation garden green space planning.Based on destructive measurements, here we chose thirty-six20m×20m quadrates from threesanatoriums artificial greenbelt in Hangzhou and according to the field vegetation survey, we got14community indicators, then stepwise regression and Pearson correlations test were carried out, a total of4simulation equations of TGB were derived. The results showed that: overall three-dimensional greenbiomass showed a normal distribution,the tree layer three-dimensional green biomass nearly taken up90percent of the of the total three-dimensional green biomass. The coefficients of determination (R2) ofthe4simulation equations ranged from0.922to0.973, no evident pattern was shown in residualanalysis which proved simulate equation could be used to predict the three-dimensional green biomassof the artificial greenbelt. The most convenient simulation equation was Y=2679.155ⅹ5+77.620,where Y was simulated TGB and x5was basal area at breast height. According to the simulationequations standard regression coefficient,basal area at breast height was the most important factoraffecting the TGB of small area artificial greenbelt.From January2012March to2009December, the air anion concentration, inhalable particulate,temperature, humidity were measured in three Sanatoriums. Based on the dynamic trend cobservationsTGB and ecological indicators,statistical analysis were carried out to find out the relationship betweenTGB and the average temperature, average humidity, air anion concentration, inhalable particulate, Inparticular, we fitted a non-linear curve between theirs and TGB,The results show: negative air ion concentration, humidity, temperature and TGB amount was positively correlated, and summer relativeto the spring, fall and winter adjustmented more obvious for the various indicators, the correlationbetween TGB and inhalable particulate was not significant; logistic curve can accurately describe therelationship that TGB with temperature, air ion concentration, humidity, with adjusted R2of0.90, TGBthreshold reached1500m3within the20mⅹ20m plots which could play a better role in regulating; Intrees, shrubs, ground covers three green structures, tree layer showed a highly significant correlationwith the temperature and humidity, the anion indicators, ground cover plants had certain relevance,shrubs correlation was not obvious, inhalable particulate with green structures were not correlatedsignificantly.Author used THI as an example, trying to establish a link between the greening amounts of humansenses. And through the five senses stimulus theory, establish an information systemt exploredapplications of TGB in the green landscape.
