Research On Landscape Design Strategy Of Above-ground Space In Jinan Subway Station Area

At present,with the rapid development of urbanization in China,urban public rail transit has been built on a large scale in China with its advantages of large passenger capacity,reducing the traffic pressure of ground transportation and facilitating people's travel,among which the most typical is the subway.When the subway line gradually forms an increasingly dense network in the city,the subway station,as its component,also begins to show the connection with the regional space,and has become an important node in the urban system.The site within the influence radiation range of the station is called the station area.Because the station area has an obvious active role in urban development,the TOD(transit oriented development)mode with the station area as the core can be popularized and practiced in urban design.With the development of the times,people's demands for the station area have also become diversified,such as highlighting the image and style of the city and carrying the cultural spirit of the city.Therefore,taking the construction of subway in Jinan as an opportunity,this thesis focuses on the analysis of the current situation of subway station area,and based on this,the research on the landscape design strategy of aboveground space in station area is of great significance to improve the urban environmental quality of Jinan and promote the development of station area.After combing the research status,main theories and practical cases related to the aboveground space landscape design of the subway station,first classify the types of Jinan Metro phase 1 stations,and divide the station types into residential type,commercial type,traffic type and cultural and educational type according to the main land use properties around the station,and then determine the research objects of the station,including spatial layout,landscape facilities,planting and greening,transportation system and crowd activities,And analyze the standards of the station area,including on-site performance,comfort,identification,accessibility and functionality.Then,through the on-site investigation of 18 representative stations of four station types,this thesis analyzes and studies the current situation of aboveground space of various types of subway stations in Jinan,and summarizes some common problems,including single land function,lack of landscape facilities,simple landscape greening,serious contradiction between people and vehicles and lack of humanized design.On the basis of the above research,this thesis puts forward the principles and Strategies of aboveground space landscape design according to the current situation of various types of subway stations in Jinan.Among them,the residential station strategy includes enhancing the accessibility between residential areas and stations,building systematic supporting service facilities,improving the station slow-moving system and vehicle parking points,and creating a high-quality station residential landscape;The commercial station area strategy includes controlling the scale proportion,creating spatial sequence,building business clusters with complex functions and rich levels,and integrating the commercial landscape of urban characteristics;The traffic station area strategy includes controlling the scale of the square,improving the spatial function,and designing the traffic hub landscape that highlights the urban style;The strategy of cultural and educational station area includes increasing the facilities and places serving the crowd of colleges and universities and creating a landscape with college cultural atmosphere.In addition,it also summarizes the common strategies used to solve the common problems of various types of stations,including reasonably defining the landscape space,compounding the functions of stations,shaping the three-dimensional landscape combined with traffic,and enriching the landscape detail design.Finally,the Olympic Sports Center Station of Jinan rail transit line 3 is selected for conceptual design,and the common strategies summarized above are used according to local conditions to generate four design concepts of "building a green slow traffic system","enriching station service facilities","organizing traffic transfer streamline" and "spring culture symbolizes Jinan" to verify the feasibility of the proposed strategy,In order to provide some useful reference for the landscape design and construction of aboveground space in Jinan subway station in the future.
