Influence Of High-Speed Railway On Urban Space Of Zhengzhou

Traffic plays an important role in the formation of urban space.The urban space will generate profound changes because of transportation.China is in the rapid development of urbanization period,urban space and urban spatial structure are rapidly changing,and the high-speed railway has been rapidly developed to flourish in China.The production of high-speed railway will generate profound influence on the urban space and regional spatial pattern reconstruction.In particular,Zhengzhou,as an important transportation hub in China,its development is particularly important in face of high-speed railway era.Based on the research of high-speed railway at home and abroad,this paper analyzes the three aspects of Henan province,Zhengzhou city and high-speed railway station,based on weighted cost grid gravitational model,fan shape analysis and stacking analysis.And then we will know the impact of high-speed railway on the different scale of urban space in Zhengzhou.The main conclusions are as follows:(1)Regional level:(1)The rapid development of high-speed railway in Henan Province has changed the regional spatial and temporal pattern,the overall time between the city has been shorten,but also exacerbated the regional city accessibility of non-equilibrium.(2)The high-speed railway expanded the scope of a day outside circle of Zhengzhou City,and showing a linear radiation along the high-speed railway,the distance between Zhengzhou and the surrounding cities has been closer,especially the site city along the high-speed railway.(3)The high-speed railway has strengthened the strength of economic ties between cities in the province and formed a "?"-shaped economic link pattern along the high-speed rail.Overall,the high-speed railway has been improved the economic capacity of Zhengzhou,and it will help Zhengzhou play a leading role of economic and cultural radiation in Henan Province.(2)Urban level:(1)High-speed railway has been stimulated the expansion space to the eastern region of Zhengzhou city.(2)It will attract government policy tilt,guide the development of Zhengzhou land direction,will give birth to a new business center in eastern Zhengzhou,Zhengzhou City will generate the Multi-center structure.(3)it will improve the traffic system structure of Zhengzhou city,so that Zhengzhou East Station and Zhengzhou City will closely linked more.(3)Station area level:(1)The high-speed railway has been stimulated the space expansion aroundZhengzhou East Station,the construction space of Zhengdong new district has been extended to Zhengzhou East Station.(2)The area affected by the high-speed railway is 3000 m circle.The increase of the area around the station is mainly in 2012.The area increases with the increase between the city and high-speed railway and reaches the maximum at 3000 m.The increase of the area mainly expend to the high-speed railway station in 2016.(3)The area around the high-speed railway station shows the structure of the circle,the land types are located in different circles,the first circle for the traffic core,the main land of this circle is to traffic-based,the formation of the main function of the core;Layer for the outer core of the traffic is supplemented expansion area,the land is mainly for the administrative office land-based;the third circle for the peripheral impact area,mainly to residential land.
