The Functional Alternation Study Of The Green Space

Green open space is the public green space in the city. The ecological function of space provides rest, entertainment for urban people. The ecological idea thorough popular feeling, green space has also become the important activities of urban people’s life. Along with the rapid development of cities and urban population rising, city land which can be used as green open space becomes less and less, the following question is the urban green space burden. In this context, it has important significance to look at the urban green open space with functional review and study again. It is necessary to solve the problem of shortage of the urban green space through the construction and building diversified functional space. Beijing, as leader of the north garden development, has a long history of garden. As the large number of visitors and welcomed by people, Purple Bamboo Park is typical. Space function as the important basis of the space usage and build the fundamental purpose of space, further study is necessary. On this basis, this article summed up the green open space of the functional space change rule and the psychological behavior of users demand mainly through the observation of green open space functional changes all the year round in Purple Bamboo Park, in order to explore more green open space functional design strategy, and to provide reference for related design and suggestions.In this paper, according to the method of combining theory and practice, from the perspective of landscape architecture, based on the analysis of related literature, combining the research of day and night, four seasons change in Beijing Purple Bamboo Park to summarize and analysis its landscape function. The following conclusions:(1) Urban green space should be designed and constructed according to the characters of local residents’ psychological behavior. Try to construct a green space which is in the interests and services of local residents.(2) Positioning of green open space design should have specific functions because use function can make space valuable. Green space should not only bring the ecological benefits, aesthetic benefits, but also has the function of serving the people.(3) Green open space has the versatility, should further study of the design, considering the diversity of space function demand, the limited feature space to the perfection of its function value.(4) On the space design and function, the green space should not be defined as a kind of space, the impact of time change should be considered in the design of the space environment and facilities. With the change of time, the change of the plant landscape, the surrounding environment and its influence on people’s psychological behavior should be considered. Integrate this change into the space design so as to improve the functional sex of the space change.(5) In the space planning and design, the various ancillary facilities design, functional architecture design and urban furniture design should be fully improved. Affiliated facilities in the green space in the space multifunctional implementation play an important role.Review and research of the space functional change of Purple Bamboo Park which is used by the more crowd is not only beneficial to Beijing botanical garden and its space multifunctional landscape, but also for today’s landscape planning and design ideas and creative theory and the practice application, etc.
