Study On Changan Capital Circle In Western Han Dynasty

City is the product of human civilization development to a certain stage,China is one of its birthplaces.The early cities in China were born during the transition from primitive society to slave society.After the development of the Xia and Shang dynasties,the cities of the Western Zhou Dynasty already had a certain scale.Spring and Autumn and Warring States period,due to social changes and economic development,a large number of cities appeared.After the establishment of the Qin Dynasty,a series of policies implemented had a profound impact on the development of the city,and the capital,county,and county system was initially formed.In the Western Han Dynasty,on the basis of Qin,some cities were restored and expanded,and the first city was Chang’an.The development of the capital is not isolated,but must rely on the comprehensive support of many factors such as region,resources,environment,society and economy.Therefore,a larger geographical area is needed,and this area is the capital circle.It can be divided into two parts: the municipality and the peripheral area.Due to the different distances,it should have different divisions and roles.For the Western Han Dynasty Changan Capital Circle,its direct jurisdiction is the surrounding areas including Lingxian and Shanglinyuan,and the peripheral areas are Sanfu other counties,and the study of the relationship between these three is conducive to understanding the development of the ancient capital circle.The content of this article is discussed from the following six parts:The first part is an introduction,including an explanation of the reasons,significance and relevant concepts of the article,as well as the review and evaluation of previous research results such as works and journal articles related to the content of the Western Han Dynasty.The second part is the evolution of the Changan Capital Circle in the Western Han Dynasty.Including the relationship between the capital and the natural geographical environment,as well as the political,economic and military background of the Western Han Dynasty,the historical evolution and capital construction of the Changan Capital Circle in the Western Han Dynasty were analyzed.The third part is the suburbs of Changan Capital Circle in the Western Han Dynasty.It is mainly divided into two parts: Satellite Chengling County and Royal Garden Shanglin Garden.Through the research and analysis of the setting reasons,layout management and population composition of Ling County,the construction process,space scope and management methods of Shanglin Garden,the functions of Lingxian and Shanglin Garden as satellite cities to Changan,the capital,are discussed.The fourth part is the outer area of Changan Capital Circle in Western Han Dynasty.It mainly discusses the changes of jurisdiction,administrative settings,population size and city type division in the peripheral area,as well as the indispensable driving factor for the development of the Chang’an capital circle-the transportation system,and then explains the functions of the peripheral area to the capital Changan.The fifth part is the influence of Changan Capital Circle in the Western Han Dynasty.It mainly discusses the impact of Chang’an Capital Circle on future capitals and the development of Guanzhong area.The sixth part is the conclusion.Summarizing the above studies,the focus is on summarizing and analysing the functional structure of the metropolitan area and the suburban and peripheral areas that play a role in Changan,the capital.It is believed that the ruler of the Western Han Dynasty,Chang’an,was determined by the rulers based on the analysis of the comprehensive situation at that time.After the capital was built,the planning for the vicinity of Chang’an and the Sanfu area ensured the safety of the capital,Changan,and eventually developed into a large city in the world at that time.
