Research On Environmental Impact Of Three-dimensional Green In High-density Neighborhoods

The research is about three-dimensional green in a high-density urban neighborhoods,The research elaborates on the development and the impact of threedimensional green building strategy.Surrounding the research of three-dimensional green in a high-density urban neighborhoods,through the study of literature on existing three-dimensional greening modes,It summarizes them as roof greening,vertical greening,balcony greening,platform greening and sink space greening,by the research of typical three-dimensional green case,the article categorize different cases by roof greening,vertical greening,building height and plant selection of three-dimensional green cases,and summarize the location and the use of different three-dimensional green cases in architectural features.Summed up the relationship between the threedimensional green and ground green and their linkages in urban space,this paper extracts the effect factor of three-dimensional green on urban greening,and describes its impact on city blocks about Green Looking Radio,the carbon cycle,rainwater collection,noise insulation,energy-efficient and temperature control.Tianjin Jiefangbei Road high density neighborhoods as the case,according to the summary of stereoscopic three-dimensional green projects,it makes different models,they are the status quo model,low-level model,model based on Milano vertical forest and model based on the “Consorcio-Santiago” building,and calculate the amount of the different Green volume,total leaf area,covering area of three-dimensional green,as the rate of afforestation,and calculate the area of radiation range,Green Looking Radio,photosynthesis amount as three quantitative indicators of urban space environment.The results show that block construction indicators,the cases of three dimensional green and Green volume have a larger effect on space environment,the plants,total leaf area,covering area of three-dimensional green have larger effects on the ecological environment,different factors have different effects on the environment.Based on the simulation above,combined with the green features and difficulties in the construction,it proposes principles of three-dimensional green design in high-density neighborhoods,and three-dimensional green design strategy in high density neighborhoods according to the effect of greening in the urban space.Finally,through reasonable threedimensional green strategy,it can guide the construction and operation,that strengthen the benefits of three-dimensional green,and promote the development of ecological construction in high density neighborhoods in the future.
