Integrated Development Of Large Railway Station's Catchment Area

The large railway station's catchment area as a node on the transport network and a place in the city has dual attributive characteristics.It plays a key role in improving the traffic efficiency and the vitality of the place,solving the fund problem in high speed rail and station construction,and coordinating the interaction between traffic and land use.The integrated study of the space of station catchment area is mainly to reflect the synergistic relationship between station construction and urban development through the in-depth analysis and research on the interaction mechanism between large railway station and urban space evolution,which is an important basic study to grasp the composition and evolution law of the substance space form of station area and new town of high speed rail.For a long time,the large railway station's catchment area construction in China has accumulated many problems,such as the split of the city,isolated construction and management between station and city,and inadequate consistence between station and urban development,embodied in fragmentary and inactive catchment area form,low land use efficiency,low traffic efficiency and unreasonable industrial structure,so the space of station catchment area cannot play its proper catalysis function.Confined to the past ontology research of station,they are difficult to solve,so it is urgent to make targeted study from the integrated perspective of synergy between city and station.In view of the above problems,the paper took the synergistic development between large railway station and urban space as the research focus and the integral thinking,system theory and traffic-guided urban development theory as the theoretical basis to construct the theoretical framework of integrated development of large railway station's catchment area and make in-depth analysis and study on the interaction between the space of large railway station's catchment area and urban space in evolution so as to guide the catchment area construction in healthy and sustainable development.The paper summarized the problems in the development of station catchment area in China and their causes and pointed out that the root lies in the lack of effective integration and synergy between station and urban space development.Based on the analysis of the coupling effect between station and urban space development,this paper started from the guiding effect of station on urban development to analyze the correlation and impact mechanism between railway station and urban space development at different urban development stages and space levels,and summarized the temporal and spatial characteristics of station and urban spaceevolution.With this start point,the study analyzed the connotation and essence of station catchment area development from the dual attributive characteristics of station territory and the interaction between traffic and land use,and established the theoretical analysis framework.On this basis,it proposed corresponding operational mode from city to station and from macro to micro according to the significant impact of station on the spatial development of region and city on regional,urban and local scales as well as the feasibility of the coordinated development between station and city to promote the integrated coordinated development.The paper put forward the comprehensive development mode of station catchment area at the level of point,integrated station and route at the level of line,and regional integration in the planning and construction of railway station at the level of plane.At the same time,it clearly pointed out that the point,line and plane are inseparable to play a role in order to form the city form with station centered intensive development and guide integrated urban and even regional development.Secondly,through analyzing the hardware and software requirement for China to have a comprehensive catchment area development,IT points that comprehensive development requires not only collaborative development and united management,but also the essence of integration of planning,development,design and management.Furthermore,through the data statistics of the station catchment area along Beijing-Shanghai line,classification comparison and cluster analysis methods were used to analyze the development characteristics of different types of station catchment areas.This paper put forward the optimization strategies of spatial organization,land use,transportation organization and other elements after the problem analysis of station catchment area along Beijing-Shanghai line,and then explored how to grasp the opportunity of station construction and promote the integrated development of station catchment area by integrating the planning,development,design and management.Based on the node and location model,the value characteristics of station catchment area along Beijing-Shanghai line were evaluated.
