Study On The Influence Of Different Dividing Patterns On The Development Of Urban Space In The County (City)

With the deepening of globalization,marketization and decentralization,China's urban space development is in a strong process of reconstruction,so the internal mechanism of urban spatial evolution and reconstruction has become the focus of academic research.At the same time,due to the adjustment of administrative divisions and the development of urban and rural space is closely related to the discussion of urban administrative division adjustment also attracted unprecedented attention.Administrative division adjustment essentially means that the process of change of power between different levels of government,which led to the role of the material space of the object of continuous reconstruction and development.The essence of the adjustment of the county(city)area can be said to be the adjustment of the administrative scope of the district and the government power.The adjustment of the administrative scope of the city is realized through the change of the boundary,and the power between the county(city)level and the municipal government The game will eventually be reflected in the adjustment of the border.This adjustment has had a great impact on the evolution of urban space,but people in the study of the withdrawal of the county area is often overlooked the boundaries of the different models of choice on the impact of urban space.Based on this,this paper focuses on the study of the impact of different demarcation models on the development of urban space.The article will be summarized repeal-county-and-set-up-district policy divided into three demarcation model:The whole system of split-type,the whole system surrounded by split,split-type.It is found that the spatial form of the city is completely subverted and the overall spatial structure of the city is changed from single center to multi-center,but the withdrawal of the county(city)and the original city area border space is difficult to integrate,the infrastructure is difficult to interoperability,leading to the inefficient waste of the border space and the highlight of the false urbanization phenomenon;the whole structure of the package promotes the rapid expansion of the size of the central city,but the overall spatial adjustment is still limited,the function of central city is still lack of upgrading,border space wastes inefficient,border effects strengthened and leads to poor quality of space landscape.The spatial space of the metropolitan area evolved from the "single center" to the "belt type,multi-group,network type" metropolitan area,and the spatial and function of the central city area was optimized,the external space enhances the quality obviously,but also easy to form a pie pie-style space.
