Open Space Design Based On Microclimate Effect Of Tree Arrangement

Study on the open space for a microclimate is always hot,but the study in an open space(such as the square)the influence of these elements on the tree is not very much,but the tree is very important o n trees shrubs and lawn structure system of microclimate.Because the tree has a huge canopy,shade it will reduce the ambient temperature,the tree leaves are produced during photosynthesis,oxygen,affect the surrounding air,transpiration and respiration of the night will produce water vapor,change the air h umidity around the tree canopy may affect the wind speed,wind or a guide block also the effect of m icro climate trees.Because of the changement of the arrangement of the trees,the surrounding microclimate is likely to ch ange,therefore,this study hopes to use the Envi-met analysis of different trees arrangement on the mic roclimate effects of different results,and get the conclusion for the transformation of the square.First,through the classification of trees arrangement,there are three types:the single,centralized and uni form arrangement of trees,after that we established an ideal model and simulated and analysis the micr oclimate,we get the effect of humidity,temperature,the wind.Then we further analyze the effect of tr ee arrangement on microclimate,taking into account the dominant wind direction in winter and summer,we made use of the conclusion to the transformation of the Gulou square,and according to the simulat ion map,we get the suitable areas,with different functional areas layout of Gulou square,through the comparison of microclimatic conditions in winter and summer in different function areas,for some micr oclimate is not ideal region by analyzing the simulation's temperature,humidity,wind speed,we added some flower,walls,which are improved,the final tree and hard shop two subsystems are superposed t o obtain the transformation of the Gulou square.After the renovation scheme Gulou square,I ues the Envi-met software for the Gulou square area again,the air flow rate,air temperature,air humidity,confirmed by microclimate tree layout after the transfor mation of the Gulou square has been greatly improved.In the design,each stage continuously through the feedback function layout and microclimate suitability contradiction simulation,and then adjust the position of some arbor solved the process to solve these problems,I benefited.The whole thesis contains about 20000 words,132 pictures and charts.
