Study On The Relationships Between Building Background And The Virtual Quality Of Urban Forest Landscape In Beijing

Some inner relationships between ontology and background could be found.To be more precise,the ontology is regarded as the basic principle in the composition of background environment.The domain and nature of the background is defined by ontology,so as the timing and spatial attribute of the background.The aesthetic quality of urban forest landscape is directly influenced by the background.The quality of the background may also affect the beauty of the urban forest landscape.The certain extent of combination between the background and the urban forest landscape may assist the function of urban forest landscape in improving environment and leisure and recreation,which is beneficial for improving the quality of environment and people's relax.By analysing the relationship between architecture as background and aesthetic quality,this paper could provide technical basis for the regulation and modification for the quality of urban forest landscape in the content of architecture as background.In addition,after knowing the local architecture as background,this paper could also be used as a reference for the construction of urban forest landscape.(1)Accepting the method of assessment for beauty,the systematically research on the quality of urban forest landscape in front of the architecture as background from close-range outside of the forest has been done.Besides SBE,ANOVA and CORRELATION ANALYSIS are also used in this text to select 9 fundamental factors that substantially influence the quality of urban forest landscape,namely the percentage of arbor,the percentage of shrub,the percentage of architecture,the green rate,the comb clarity,the index of colour comparison,the landscape naturalness,the seasonal variation and the colour richness.(2)According to the analysis of the relationship among the portion occupied by architecture,the portion occupied by arbor and shrub,green rate and aesthetic quality,when constructing urban forest landscape given certain architectural background,the portion used by green rate,arbor,shrub,architecture and streets should be 70%,50%-60%,10%-15%,20%,10%separately.By adopting this method,the beauty of landscape could peak.(3)Using the principal component analysis and step by step regression analysis,the system for the appreciation of relationship between the beauty of urban forest landscape and architecture is established.Based on this,the model of linear and nonlinear is established.
