Research On The Ecological Infrastructure Space Model Of Quxian Community In Haerbin

At present the city community have lots of houses?residents but less of land and green space. The environment quality is dropping and the central vitality is declining.With the speeding up of urbanization process,the community extensive development of community speed up the urban construction but brought serious damage to the urban ecological environment, such as ecological corridor blocked, the lake wetland is encroached, loss of biodiversity, etc.With the emergence of ecological problems,ecological concept more popular. The construction of city call more gr een space,ecologiczal planning is getting more and more attention.This paper clarified the differences between residential green space and community EI. This paper also sumed up the construction of EI in various scales. Community EI needs a new planning method which different from traditional model and the larger scales.The object of the problem is eight community in the center of Har bin. Making statistics and analysis of the existing green space sumed up the common problems of EI.Aiming at the problem of insufficient amount of EI, this paper puts forward development model of community based on the theory of "vertical city". The model emphasize the mixed land use,the perpendicular development space,the dimensional transportation so as to run out more space of EI.According to structure problem,this study put forward the pattern of network corridors and hubs based on the landscape ecology "matrix- gallery – plaques". In the aspect of network,structure this paper put forward typical model which adapt to different communities. In the aspect of hubs,this paper put forward planning model of hubs based on the principles of patch size, patch layout, the patch shape. In the aspect of corridors,this paper put forward the planning model of green road corridors and green belt corridors based on the related principles.This paper gave an case of Quxian community. Renewing the community space and composing the development model of mixed land use achieve more green space.In the aspect of urban design, the planning of vertical architectural space of transfer multi-level EI space.In terms of EI space construction, choosing right network structure model of the community, constructing community patch,corridor which forming the high connectionof EI network structure.The innovation of this paper is the combining of urban planning design method with landscape ecology principle,using vertical community development model to increase the total space of EI and putting forward the spatial planning model of EI at community scale.Through the construction of community EI,integrate the natural ecosystem to community.Buildding community base on the complete ecological infrastructure structure system, as a community of natural skeleton, maintain ecological safety,and provide ecological services.
