The Evolution And Application Of The Spatial Pattern Of The Vital Street In Urban Commercial Area

In the process of contemporary urban development,with the continuous deepening of the complex and three-dimensional spatial development of the urban business district,commercial areas present increasingly diversified spatial patterns to bear the efficient urban operation and the growing economic development needs.However,in the application process of commercial street spatial patterns,some inappropriate spatial patterns lead to the decline of street spatial quality,negative space and gradual loss of street vitality.It is difficult for the streets to provide comfortable and pleasant sensory experience and convenient activity place for pedestrians,which leads to a large number of empty retail houses and decay of newly built commercial areas.In recent years,people's understanding of the construction of vital streets has been deepening,and many countries and regions have begun to reflect on the impact of street space on the vitality and explore the means to reshape street vitality through the study of cases,so as to summarize the vital streets space pattern that meets the development needs of today's urban business district.Vital street in urabn commercial area is the concept put forward to shaping street vitality based on the above development background.It is a kind of street space pattern that takes creating the vitality of streets as the core.The paper takes urabn commercial area which can reflect street viality most as the research scope of street vitality,with commercial energy street as the research object.Based on the characteristics of the city downtown streets function homogeneity,the paper uses the unit method,and with the basic unit as the research starting point,from the micro level of urban design to explore the commercial vitality street space unit elements,basic characteristics and inherent law between elements.By carding the domestic and international business district dynamic evolution pattern of the street,the paper presents that spatial patterns of evolution rule and the characteristics of the space patterns to explore the vital problems of vital streets in Shenzhen,analysis of application cases characteristics and spatial patterns and the inner motivation of the problems,and then makes recommendations for optimization to cases in Shenzhen.Based on the concept of vital streets,this paper analyzes the spatial pattern and vital elements of vital streets in different periods,and systematically establishes the theoretical framework of street vitality from the perspective of the concept and internal relationships of the three vital elements.And to enhance the quality of vital elements wholely,the thesis discusses its vitality of street space applications.On the basis of constant accessibility,the research presents suggestions to improve the spatial unit of application street patterns and repair vital elements.With the expect to provide theoretical basis and practical support for the reconstruction of vital street elements in commercial areas and better interaction between the elements to ensure the attraction of street space to pedestrians.To make the vital streets in commercial area become an attractive urban space with pleasant environment,supporting activities building frontage and fine storefronts,and promote the healthy and sustainable development of the business area.
