Research On The Application Of Digital Landscape In Urban Construction

Since the 1980 s,economic development has been increasingly information-based,globalized and networked,and productivity and competitiveness are increasingly dependent on the processing and use of information and knowledge data.With the influence of informatization,globalization and network,people's lifestyle,urban environment and urban space are undergoing great changes.After former U.S.vice President al gore put forward the concept of "digital earth" in the 1990 s,China also launched a research and construction boom of "digital China" and "digital city"."Digital landscape" also appears in this context.The international digital landscape conference hosted by Germany attracts many landscape gardeners and information technology experts to communicate and collide each year.Compared with the international situation,domestic research and discussion on "digital landscape" started late.As a new concept,"digital landscape" has not yet been defined in a unified form.It is generally believed that digital landscape is a combination of modern digital display technology and 3D printing technology with traditional sculpture,lighting,horticulture and waterscape.Such as by numerical control technology the use of text,images,lighting,sound,image,and a variety of interactive behavior,etc.,to form a can control the landscape space,create a new type of landscape beyond traditions,beyond imagination.Domestic scholars UN,Zhang Tongkai,chun-hui li said,"digital landscape" is the combination of the digital technology and landscape architecture,is different from traditional paper,pictures or objects to represent the landscape technology,is with the aid of computer technology,the integrated use of GlS,remote sensing,telemetry,multimedia technology,computer network technology,artificial intelligence technology,virtual reality technology,simulation technology and digital technology such as sensor technology,the landscape information collecting,monitoring,analysis,simulation,create,reproduction process,methods and techniques.With the popularity of computer and network,digital technology is in an unprecedented trend of penetration in the social from all walks of life,influencing and changing people's life,including the impact on the urban landscape design and its formal definition.Hence the uncertainty of the form definition of "digital landscape".The application of digital technology in urban landscape design,to realize the interaction between people and landscapes,strengthening the contact between people and landscapes,is a comprehensive,three-dimensional,the use of interactive process.On the basis of the characteristics of "digital landscape",this paper studies to urban landscape planning and design process as the main line,through the analysis of landscape data acquisition in digital landscape,landscape,landscape evaluation,landscape visualization to build this several aspects about the application of analysis.The digital intelligence of each process of urban landscape planning and design canimprove the scientificity,precision and intelligence of urban landscape planning and design.It provides theoretical basis for solving the problems of land space utilization,ecological environment and hydrological system in urban environment and promotes the construction of digital city.This paper further discusses the change of public participation form and way under digital technology,the foreground and trend of digital technology in urban landscape.Finally,the prospect and hope of "digital landscape" in future urban construction are prospected.
