Study On The Spatial Form Of Changsha-Zhuzhou-Xiangtan Urban Cluster From 2008 To 2018

In the new era,globalization and informatization continue to promote the development of urban clusters,expanding the industrial and economic scale of urban clusters,and affecting the spatial form and combination of urban clusters.ChangshaZhuzhou-Xiangtan Urban Clusters is the most important growth pole in the rise of central China strategy,also is an important part of the "urban cluster in the middle reach of Yangtze river",occupying a corner of "Triangle of Central China "in the National spatial planning for development.As the highest form of Hunan province regional space form,it constantly strengthens the relationship between regional cities and constitute a more compact space organization.At present,the Changsha-ZhuzhouXiangtan Urban Cluster is stepping into the stage of high-quality development in the new era and making steady progress towards the construction of high-quality new urban functional areas.Therefore,clarifying the development mode of the regional spatial form of Changsha-Zhuzhou-Xiangtan Urban Cluster,exploring its law characteristics and evolution dynamic mechanism can lay a theoretical foundation for the rational,orderly and sustainable development of the future urban cluster and accelerating the regional integration.Based on the summary and analysis of the past development status of ChangshaZhuzhou-Xiangtan Urban Cluster and the principles of data availability,this paper chooses to conduct theoretical and empirical research on the spatial form of ChangshaZhuzhou-Xiangtan Urban Cluster from 2008 to 2018,which is mainly divided into six parts.The first two parts are the introduction and the theoretical research progress of urban cluster spatial form.The third part is about the evolution of the spatial form of Changsha-Zhuzhou-Xiangtan Urban Cluster before 2008.By searching for historical data,using GIS and RS data,empirical research is carried out on the spatial form of Changsha-Zhuzhou-Xiangtan Urban Cluster in different periods.The fourth part is 2008-2018 Changsha-Zhuzhou-Xiangtan Urban Cluster spatial form evolution research,firstly by GIS and RS analysing land use status of the Urban Cluster,secondly using the Boyce-Clark to research the dominant direction of spatial form expansion and development patterns of the Urban Cluster,use of space form compactness,expansion speed and strength,elasticity index and ecological encroachment index to analyse morphological characteristics of the urban space,the final analysis of the correlation of the Urban Cluster of each land use type,obtaining the influence degree of different land use types on the Urban Cluster spatial form.The fifth part is 2008-2018 ChangshaZhuzhou-Xiangtan Urban Cluster spatial form evolution driving force research,by using GIS and statistics methods,making dynamic mechanism divided into two aspects of internal and external,contains the natural conditions,policy changes,administrative division adjustment,traffic guidance,social economic changes,adjustment of the urban function,regional culture and consumption idea change eight driving factors.The sixth part is divided into prediction and revelation.It makes a comparative analysis and research on the spatial morphological characteristics of Changsha-ZhuzhouXiangtan urban clusters and other urban clusters,and predicts and makes revelation on the spatial morphological evolution of Changsha-Zhuzhou-Xiangtan urban clusters.
