Study On Boundary Space Of Landscape Architecture In Xishu Garden

The boundary space of the garden undertakes the function of limiting the scope of the garden space and carries the responsibility of communicating the inner and outer space of the garden.Boundary space divides and connects the internal and external spaces of different forms of garden space,which effectively increases the content and extensibility of garden space,thus enriching the landscape effect of garden space and modern cities.Based on environmental cognition and environmental experience,the boundary space of Xishu’s representative garden,Yanhuachi,Guihu and Donghu is made a study,the characteristics of the formal constituent elements of the boundary space of Xushu garden is made an analysis,and the changes of human behavior in the boundary of node space,the influence of sequence space path change on human behavior in boundary,the creation of boundary space context and artistic conceptio is made a study,and the comprehensive evaluation system of boundary space of Xushu garden is constructed,which provides guidance for the development and innovation of the boundary space of Xishu.In the elements of the form of boundary space,which is guided by the principle of formal composition,the boundary space of the Xishu garden has prominent "point,line,face" constitution.In the boundary space of point shape,pavilions are mostly located at the terminal of porch or at the connecting point of porch,and most of pavilions and pavilions exist separately.Most of pavilions are located at the nodes of boundary space,and rockery design are arranged on the boundary line of barge,or adjacent to the wall.In the line shape,the wall and corridor are the typical elements of the line form,and the outer wall space segmentation function is obvious.In the shape of the surface,the lake and the pool are represented.The layouts in the three gardens are mainly water surface,with water-wave wrinkling,curving bridge building shadow,which constitutes rich garden boundary space.Taking visitors as the object,the visitors’ experience of boundary space is made a study from three aspects,such as node space,sequence space and space construction.By the use of semantic analysis method,a questionnaire is sent to visitors to investigate the behavior of people in node space with strong attraction,and to analyze the size,territorial sense,closeness,interpersonal distance,spatial binding,flow change and residence time of each node,and it is found that:From the size of the node,the sense of spatial domain and the sense of closure,the spatial boundary of the node of the Yanhuachi is dominated by the space under the corridor,the courtyard space surrounded by the building and the space surrounded by the courtyard wall,among which most of the space fields have a strong sense of closeness.The boundary space of Guihu is mainly divided by water surface and barge line,whose area is large,the sense of closure and direction of space domain is the weakest,only the space field surrounded by the ancient city walls has a better feeling.The Donghu is dominated by courtyard space,corridor space and ancient city wall enclosed space,and a few space fields have a strong sense of closeness.In the distance of interpersonal communication,it is found that the three garden visitors are mainly individual activities,two or three groups,most of them are middle-aged and elderly groups.Close distance is maintained near the water area,near the landscape node and in the rest area.and the social distance near the entrance or near the next space intersection are maintained.It is found that the landscape in seasonal phase change has a great influence on tourists’ tourism activities in the study of air constraint,flow change and residence time.When the seasonal landscape changes obviously,most visitors choose to stay near the landscape node,and their stay time is longer.Mild or cool weather can stimulate visitors to engage in outdoor activities,their social activities are more frequent,types are more abundant,and the space is less binding on visitors.In the node space,visitors like to be in the pavilion.Under the porch,the boundary space with rest function under the eaves makes tourists socialize,and the teahouse area attracts the most,while the rich landscape can effectively prolong the stay time of tourists.In the sequence space,the environmental experience sequence is selected based on the path,and the dynamic and dynamic changes of the landscape nodes,the radiation radius and the field of view of the nodes are mainly studies,including the influence of grey space change on human behavior in the boundary and the psychological perception of the path.It is found that in the three garden sequence spaces,because the landscape layout is mainly water,the dynamic and dynamic changes of landscape nodes are caused by alternation and rich changes,and the rhythm of each sequence is different.The landscape nodes of Yanhuachi are more compact,the centripetal force is better,and the ability to gather the flow of people is also better.Because of the large area of water area,Guihu increases the depth of field,the field of vision is broader,and the visitors get better viewing effect.Donghu has the most visual landscape in the sequence of main buildings,and has the strongest correlation with the surrounding landscape.In the study of sequential grey space,it can be found that visitors like to stay in grey space,which greatly improves the spatial utilization rate of boundary space,and the arrangement and change of grey space adds interest to the experience of sequence space.It can be found from the psychological perception of sequence space that the vocabulary described by the three garden sequence spaces is mainly limited,aesthetic,safe,pleasant and attractive.In the creation of boundary space context image and spatial artistic conception,all three gardens have profound cultural connotations.In the construction of artistic conception,it is found that the boundary space limitation is fuzzy,the leaky window on the wall and the penetratign view in the mountain and stone,so that the garden space merges with each other and affects each other,and the boundaries become diverse,flexible and changeable.The boundary space turns reality into emptiness,realize the combination of deficiency and reality,and the space has emptiness and consistency.The boundary space is simple and natural,the boundary of the garden is built with the local material,merging the nature into every part of the garden,which is the characteristic of the Xishu garden.In the construction of the boundary space comprehensive evaluation system,three levels are built on the basis of the node space,the sequence space and the boundary space.The evaluation system of the boundary space of the Xiashu garden is constructed by using the analytic hierarchy process,and the three garden boundary spaces are comprehensively evaluated by the use of the fuzzy evaluation matrix.In the end,it is concluded that the comprehensive evaluation grade of the three garden boundary spaces is "excellent".In the creation of boundary space context image and spatial artistic conception,all three gardens have profound cultural connotations.In the construction of artistic conception,it is found that the boundary space limitation is fuzzy,the leaky window on the wall and the penetratign view in the mountain and stone,so that the garden.
