The Study On The Outdoor Landscape Space Of Chengdu Taikooli Commercial Block

City commercial block is closely related to our life,and fully displays the urban characteristics and style in the city development,commercial street landscape space plays an important role in the development of urban public space.At present,the study of the commercial street landscape space is limited to the space structure,design elements,regional context and aesthetics,but has not been systematically studied from the perspective of environmental psychology,in this paper,we try to use the method of quantitative and qualitative analysis to study the outdoor landscape space of commercial blocks from the point of view of environmental psychology.On the basis of the research of domestic and foreign commercial street landscape space,,take the guidance of environmental psychology for outdoor commercial blocks landscape space as a starting point,select the Chengdu Taikooli commercial block as the research object,through the field experience of the observation space,study the outdoor Taikooli landscape space from the "environmental cognition,environmental experience,environmental assessment" three aspects.On the level of environmental cognition,understanding the gonfiguration by drawing the block map,and knowing the size,depth and distance perceptions of the street by analysing the cross section of the street.Through the questionnaire survey and field observation,collect the cognition of the pedestrian on the memory of the city image and the response to the map,found that pedestrians always remember the streets by sequences,have deep images of sculpture,vegetation,curtain wall,fountain and other distinctive landscape elements,and also form the overall impression of the block by the local landscape elements.Under the guidance of environmental behavior theory,through the questionnaire survey and field observation of timing analysis,study the effects of environmental factors on the behavior of pedestrians blocks stimulation,behavioral constraints and social distance,it is found that the landscape elements of the landscape nodes in the slow zone are rich and the environment is better,but there are more problems in the landscape nodes in the fast zone;rainy days and hot days will constrain the pedestrian behavior,prompting the majority of pedestrian activities in the top interface of the space;interpersonal distance of social groups in the main square is less than the person who moves alone.On the level of environmental experience,from the three levels of node-sequence-the overall environment to study the experience of pedestrians on the environment.In the node space,measure and analysis the spatial scale,the sense of domain,the sense of closure,the quantity and density of the landscape facilities,the length and density of the pedestrians,it was found that most of the nodes in the Taikooli block are within 60m,the spatial scale is appropriate,and more than half of the nodes are well closed;and the flow of people of three main square(Daci Square,East Square,West Square)the flow of people showing hump trend,in the day of 11:30 and 14:30 in the two peak,the pedestrian stays longer in areas with rich landscape elements;also found that the density variation of the East and west square is large,the two node space flow changes frequently,spatial mobility;and some nodes in the landscape space sitting stool surface smooth inclined,partially shaded trees veins sparse problem,affecting the experience of comfort of pedestrians.In the sequence space,research the continuous D/H ratio,the changes of opening and closing of both sides on the street,and the distribution of gray space on the sequence,found five sequences in Taikooli block changes rich,staggered changes between open and closed,compact,each sequence changes in the rhythm is different;These landscape nodes in five main sequences distribute unequally to make the rhythm of pedestrians change,however,the static and dynamic changes in the sequence are not balanced,the static change is the majority,lack the dynamic change.In the whole space,experience the observation of block image,cultural mood,found the Taikooli is in better multiple atmosphere of modern and traditional,religious and secular,for examples,the word tower create a culture of respecting nature and art,tea houses along the streets create a thick atmosphere of leisure life.and those commercial shops along the street create a modern fashion rhythm.On the level of environmental evaluation,according to the structure of the"point-line-face",summing up the above research elements to construct commercial blocks outdoor landscape space comprehensive evaluation system based on environmental psychology.Using Analytic Hierarchy Process and Fuzzy Comprehensive Evaluation method to carry on the comprehensive evaluation of the Taikooli block outdoor landscape space.Finally,the conclusion is drawn that the comprehensive evaluation of the outdoor Taikooli landscape space is"excellent",which provides an new idea and method for the comprehensive evaluation of the outdoor landscape space of commercial blocks.
