Research On Spatial Form Characteristics Of Civil Defense Settlements In Yuxian Area

Hebei province's unique geographical location,complex topography,important strategic positioning,and diverse ethnic cultures have created a variety of ancient villages.Zhangjiakou Yuxian is one of the concentrated distribution areas of ancient villages in Hebei Province.Historically,Yuxian was often plagued by adversaries.Many civil defense settlements have been built for seeking stability and prosperity,forming a unique settlement space.This paper takes the civil defense settlements in Yuxian as the research object and summarizes the characteristics of the civil defense settlements in the region.The structure of the paper consists of three parts.The first part is chapter 1,which is the preparatory stage of the thesis research.Chapter 2,chapter 3 and chapter 4 are the second part,which is the main body of the dissertation.It analyzes the objects from three parts,which are the macro,meso and micro.The third part is chapter 5,as a case study of the paper.Chapter 1 introduces the background of the thesis topic,defines the purpose and significance of the study,clears the object and scope of the study,defines the relevant concepts,reviews the research status at home and abroad,determines the research methods,and formulates the framework of the thesis.Chapter 2 analyzes the distribution of civil defense settlements in Yuxian from the macroscopic level.First,it outlines the Chinese traditional defense settlements.Secondly,it sorts out the profiles of Yuxian County.Then,it summarizes the overall distribution characteristics of the civil defense settlements in the Yuxian.Finally,it summarizes the concept of the civil defense settlements location in the Yuxian.Chapter 3 analyzes the forms and characteristics of civil defense settlements in Yuxian from the meso level.First,it introduces the influencing factors and reference prototypes of civil defense settlements.Second,it classifies civil defense settlements.Finally,it summarizes the forms and characteristics of civil defense settlements.Chapter 4 analyzes the composition and characteristics of civilian defense settlements in Weixian from the microscopic level.The spatial determinants of civil defense settlements in Weixian County are analyzed.Then,the composition and characteristics of the space are analyzed,which are fortress wall system,architectural,square space and street-and-lane.Chapter 5 analyzes the spatial morphological features of the West Fortress.First of all,it introduces the overall concept of West Fortress.Secondly,it analyzes the system space of the Fort Wall,the architectural space,square space and the street space respectively.
