Research On Spatial Evolution And Development Strategy Of Urban And Rural Settlements In Gucheng County Based On Multi-source Data

Since the reform and opening up,the urban and rural settlements have changed greatly in China.However,the imbalance of urban and rural settlements space development and the isolated development of urban and rural areas restrict the sustainable development of urban and rural economy and society in the future.Among them,the southeast of Hebei is located on the edge of Beijing Tianjin Hebei Urban Agglomeration,but it is an important part of the coordinated development of Beijing,Tianjin and Hebei,and the imbalance of regional development is serious.The polarization effect of Beijing Tianjin on surrounding areas is far greater than spillover effect.The economic and social development of the region is relatively backward,the county administrative division density is high and the county development is generally faced with unbalanced development,the urban and rural settlement space system is deformed,and the development power of urban and rural settlements is insufficient,which seriously restricts the healthy and sustainable development of the region.At present,it is aimed at the county town in Southeast Hebei Province The study of rural settlements is almost in a blank state.This paper selects Gucheng County as a typical case of urban and rural settlements in Southeast Hebei Province.Based on multi-source data and spatial information technology,this paper analyzes the evolution characteristics,evolution rules,influencing factors,dynamic mechanism and spatial development of urban and rural settlements in the former county,forecasts the development trend of urban and rural settlements in the future,and puts forward the development of urban and rural settlements The exhibition and planning strategy provide reference for the spatial development of other county settlements in Southeast Hebei.The first part is to study the theories and research trends and practical experience of urban and rural settlements at home and abroad,analyze the existing research deficiencies and find the research breakthrough point,and then construct the theoretical framework and multi-source data technology system of urban and rural settlement spatial evolution.The second part,based on multi-source data,the study of urban and rural settlement spatial evolution of the Gucheng county is carried out from the two levels of the county space category and the key settlements themselves.In the study of the spatial evolution of urban and rural settlements under the county space,the evolution of the settlement patches in space and space expansion are analyzed through the evolution of the urban and rural settlements space scale;through the agglomeration The spatial distribution of settlements is analyzed,including the spatial distribution,the spatial proximity,the spatial density distribution,etc.;the spatial distribution pattern of the settlement is used to analyze the structure model of the spatial scale,spatial system and spatial connection of the settlement in the county.Based on the evolution analysis of the settlement itself in the central city,it mainly includes the spatial expansion and the evolution of the outer space form of the settlement,the spatial change of the functional land of the settlement,the evolution of the internal space structure and the landscape green space structure of the settlement.The detailed analysis and research is carried out from the external space and the internal functional space of the settlement,and then the evolution characteristics of the settlement in the central city are understood Signs and rules.The third part,analyzes the evolution law of urban and rural settlements in the Gucheng city,analyzes the influencing factors of urban and rural settlement space evolutio,and analyzes the dynamic mechanism of urban and rural settlement spatial evolution in county areas.The dynamic mechanism of urban and rural settlement evolution is summarized as follows: natural environment is the basis The basic power,economic development is the core power,urbanization is the direct power,the location transportation is the supporting force,and the planning policy is the guiding force.The fourth part,according to the above research content,further analyzes the urban and rural settlement space development problem and forecasts the future development trend of urban and rural settlements,and puts forward the development goals and paths of the settlement space from three aspects: optimizing the settlement space scale,coordinating the spatial layout of urban and rural settlements,and planning the urban and rural spatial development pattern.In view of the future development trend and development of county urban and rural settlements,the paper puts forward the spatial development and planning strategies,which provides guidance and reference for the healthy and sustainable development of urban and rural settlements in Gucheng and other counties in Southeast Hebei.
