Investigation And Research On The Spatial Structure Of The Station Area Of Xi’an Metro Line 2

After nine years of operation and development of xi ’an subway line 2,the surrounding areas of its stations have become indispensable public places for the daily life of xi ’an citizens,and have exerted a profound influence on the urban spatial structure of the areas within the scope of its influence.In recent years,with the accelerated development of Xi ’an urban rail transit,it is very important to fully understand and recognize the urban spatial structure characteristics in the affected area of subway line 2 station for the spatial planning of the medium and micro regions and the improvement of human settlements environment.Therefore,it is of great practical significance to study the sustainable development of the regional spatial structure to start with the regional scale station space and carry out an in-depth and comprehensive survey of the station space structure of Xi ’an subway line 2.This article uses multidisciplinary theories and methods,taking the impact areas of each station of Xi’an subway line 2 as the survey object,and taking "method theory-constituent elements-survey elements-survey methods-analysis methods" as the core idea,from the region from the perspective of scale,a set of investigation and research method systems suitable for the spatial structure of the station area of Xi’an subway line 2 was constructed to explore the spatial form,layout and density characteristics of the subway line 2 station area.Based on the concept of station space development,the corresponding recommendations for station space structure optimization and research implications were formulated.First of all,by analyzing and summarizing the relevant research results and future research directions of the spatial structure of rail transit stations,we will find a breakthrough for the writing of this article and lay a theoretical foundation for the research of this article.Second,through relevant basic research,the relevant theories and methods of investigation are sorted out and analyzed.And through discussing the application of big data in investigation and research,the guiding contents in different policies and regulations documents are compared and the spatial structure characteristics of stations under different development modes are summarized,which provides guidance for the construction of investigation method system and the formulation of relevant optimization suggestions below.Third,based on previous research results,the research method system of subway line 2 station area spatial structure is constructed from four parts: investigation object,investigation scope and type,investigation elements,investigation and analysis methods.Fourth,using the research method system of investigation methods,a systematic and comprehensive investigation and analysis are carried out on the form,layout and density of the station space structure of Xi ’an subway line 2,and the characteristics and laws of the station space structure of subway line 2 are summarized.Fifth,based on the relevant laws and regulations and development concepts as reference and guidance basis,and on the basis of the spatial structure characteristics of subway line 2 station area,corresponding optimization suggestions are formulated.At the same time,rational reflection is made on the survey design and data acquisition in this paper,which provides enlightenment for the investigation and study of station area spatial structure of Xi ’an subway line 2.Finally,for the conclusion and prospect of this study,it summarizes the main research conclusion,research innovation and expansion direction for follow-up research.The research can provide theoretical and technical reference for the investigation of the spatial structure of the station area at the regional scale.Using the cross-fusion of multidisciplinary theory,a set of "method theory-constituent elements-survey elements-survey and analysis methods" The formed research method system reveals the characteristics of different levels of the spatial structure of the Xi’an subway line 2 station area,and formulates suggestions for the optimization of the spatial structure of the Xi’an subway line 2 station area,providing specific information for the spatial planning of the Xi’an subway station area The technology and data support improve the scientificity and operability of the investigation and research of the spatial structure of the station area.
