| In the landscape design since ancient times,the application of light and shadow is common.Its participation makes the landscape more vigorous and dynamic,and makes the landscape level more dynamic and changeable.However,for a long time,the characteristics and functions of light and shadow in garden space have not been systematically and effectively studied.On the contrary,in many modern landscape construction,only the design of physical elements is emphasized,while the role of natural elements such as sound and light in landscape design is neglected,resulting in the emergence of a large number of homogeneous spaces,and the lack of harmony between light and shadow makes the space dull and dull.Until recent years,with the improvement of people’s aesthetic needs,the use of light and shadow in gardens has been gradually concerned.However,at present,the study of light in gardens tends to subjective evaluation of the beauty of light and shadow in gardens and landscape lighting in gardens,while few studies take natural light as an integral element of landscape.With the introduction of the concept of "Scenery",the concept of "Scenery" has attracted people’s attention again,while the series of studies on "Scenery" has just begun.For thousands of years,Chinese classical gardens have pursued the interest of natural mountains and rivers,and the use of natural light and shadow can better reflect the artistic conception of landscape "though made by human beings,it is like heaven opening".In many previous studies,the study of light is based on pure physics,through the illumination,color temperature,spectral distribution and other characteristics of its research,which hampers people’s comprehensive understanding of light.In fact,light not only has its own physical characteristics,but also has social,humanistic and other spiritual characteristics.The presentation and change of light are not only reflected in its physical characteristics,but also accompanied by people’s physiological and psychological perception.Therefore,the study of light and scenery must combine subjective and objective aspects.Firstly,this paper summarizes the background of this topic and the research summary at home and abroad.Based on the existing research of landscape,and combined with the related theories of landscape aesthetics,architectural optics and environmental psychology,the concept of landscape for natural light is defined in detail.That is,landscape is based on the characteristics of natural light and its transmission principle,with light and shadow as landscape elements,and light is transmitted by scientific and aesthetic methods.Information is combined with other landscape elements and perception of landscape environment is made up of visual media.On this basis,further theoretical research on its constituent elements,historical origins,performance characteristics and so on is carried out.Landscape architecture is the space where people interact most with each other in garden space.Based on the types and characteristics of gardens in China,this paper defines the research object as the landscape of gardens in Suzhou classical gardens.According to its use function,garden architecture is divided into three categories:practicability,ornamentality and connectivity,and the construction of its landscape is studied separately.According to the usability and ornamental characteristics of garden architecture in garden space,this paper studies from three aspects: light distribution,light perception and light comfort.The purpose is to explore the performance characteristics and influencing factors of pleasant and comfortable landscape architecture combined with the objective performance and subjective feeling of landscape,so as to further study the construction methods of Landscape Architecture in Suzhou gardens.Finally,combined with the qualitative and quantitative research results,we get the universal research conclusion,that is,the principle and method of landscape construction in landscape architecture.Taking the landscape design of the demonstration area of Qingzhaofu in Jinan as an example,we demonstrate the application of the research conclusion in practical cases.It is hoped that this study will arouse people’s attention,appreciation and Research on landscape in gardens,with a view to providing some reference for the design and construction of today’s garden space and gardening architecture. |
