Research On The Contour Control Of Building Groups With Mountain Background Based On The Visual Perception Preference

Mountain landscape is an very significant natural landscape resource in most cities of China.The rapid development pressure forces the city to require a certain building density and unit capacity to ensure the concentration and operation efficiency of functions,which leads to the building height of the city rising.With the rise of the building height,the original harmonious relationship between buildings and mountains has gradually evolved into threats,confrontation and even destruction.In recent years,with the request of "seeing the mountains,seeing waters and remembering hometowns",the development of the City Betterment and Ecological Restoration Programs,the protection and utilization of natural landscape resources in cities has become an important issue in urban planning and construction at this stage.This paper is based on the outline of the building group in the background of the mountain,taking photos of real cities scenes as samples,taking the public preference value as the evaluation criterion,and taking stimulation and pleasure as the measurement criteria of environmental perception variables.This experiment relies on public perception preference survey to collect data.By qualitative analysis,the relationship between public preference and environmental perception attribute is explored,and the public perceived higher levels of pleasure associated with higher preference values At the same time,the stimulation degree and the pleasure degree presented a higher negative correlation,that is,the higher degree of stimulation leads to lower degree of pleasure.Further more,through quantitative analysis,the relationship between public preference and the quantitative control index of building group contour lines is explored.It is found that 5 quantitative control indicators have a strong influence on public preference value,and they are suggested to be a single quantitative control index that affects the public preference value.On this basis,this paper tries to make some suggestions on the contour control of the building group with the background of the mountain,and makes a subtle supplement to the research on the quantitative control of the landscape.
