Research On Optimization&Regulation Of Land-use Around Urban Rail Transit

Currently, urban rail transit has entered a period of rapid development in China metropolises.However, the theoretical research on land-use along urban rail transit corridor is relativelylagging behind. In the past dozen years, rail transit has sprung up in Guangzhou, and initiallyformed a rail transit network. Meanwhile, the guidelines of transforming the urban structure andspatial design through the rail transit began to take shape.In terms of joint development, the areasalong the the urban tranist have accumulated a lot of valuable experience and lessons, and havethe typical characeteristics and common problems which are also possessed by many metroplis inthe urban transit area development under the rapid development of rail tranist in China. Thispaper, from the perspective of empirical research, had a survey and related research on theland-use surrounded110subway station in Guangzhou, explored optimization strategy ofsurrounding land-use from a multi-disciplinary overlapping aspect. The aim is to provide someadvices for the future construction of Guangzhou rail transit and surrounding land-use optimizingcontrol, and also offer empirical reference to the other metroplis of China on this hand.This pager is mainly divided into three parts as follows:The first part is the basic research, which has analyzed a number of document literatureabout the study of the current rail transit station land-use and traffic interactive feedback at homeand abroad, and some practice or empirical study about relevant construction in typical citiesnationwide and worldwide. It has built the framework of study about land for the urban ratiltransit station from the following four aspects: theoretical basis, practical application, researchperspective and technical support. Moreover, it has combined the develop history of Guangzhourail transit, analyzed the optimizaing trends and the accompanying challenges of urban rail transitstation area. It established a solid foundation for later empiracal research and optimizing strategy.The second part is the empirical research, which is the core of this paper. It is mainly tohave the empirical research on the surrouding land-use which is combined with the existingsubway station and collect the first-hand data through the on-the-spot reconnaissance. It analysedspatial elements of site area, and built GIS integrated database based on the idea of GIS spatialstratification. At the same time, it made full use of GIS platform and all kinds of spatial analysisto conduct a multi-demenstional empirical study from the different spatial scales, including urban scales and site blocks scales. From social dimension, we studied the spatial coupling relationshipsbetween site network and urban public center. From economic dimension, we studied therelationships beetween site network and benchmark land price of the city. From spatial dimension,we studied the spatial layout of different kinds of station land use and the characteristics ofevolution of typical spatial form in different times, and so on. Th paper had a thorough analysison the current features and exiting problems of land use around the existing subway staion inGuangzhou. It provided a powerful empirical research for the next part.The third part is the strategic study, which is based on the above important extension andexpansion of empirical research and the dual charateristics of rail station area-node and site. Itprovided relevant optimazing counterplan from the macro, meso and micro levels, and suggestedto build a rail network system highly coupled with the urban public center and establish a siteclassification system with apprarent public center characteristics blended the traffic node and citynode together. It proposed to combined the optimization of urban rail transit station areasproperly with the regeneration of the whole city through building station placemulti-dimensionally, which is assisted by rail transit station. It also had a reflection and providedoptimizing ideas combined with the land use around the existing subway station in Guangzhou.
