soldiers must contend for,and Jiange County City rises under this background.This paper combs the process of the change of Jiange City from the perspective of historical geography,and summarizes the lessons learned,and provides reference and reference for the development of Jiange City.In the 22 nd year of Jian'an in the Eastern Han Dynasty(217),Dangde County was established in the territory of Jinjiang County(the site is located in Hanyang Town,the name of the city is Huanglu City),which belongs to the Zi'tong county.During the Three Kingdoms period,due to the influence of the size of the Jianshan Mountain,the Han Dynasty set up a cabinet and set up a guardianship to become a military key.Its special geographical location plays an important role in history.In the third year of Yonghe in the Eastern Jin Dynasty(347),in the new town of Jinshou County,Jiange County(the ruler is located in the lower town of Da'cang Dam,the old city of Xiaojian),the name of the Jiange was first seen here.After several years of resurgence,in September 2003,Jiange City moved from Pu'an Town to Xia'si Town.Jiange City used to be a state,county,government,and county government,with a history of more than 1,700 years.Jiange City is the political center of Jiange County,with convenient transportation and relatively good economic conditions.However,in the history of frequent population movements,while promoting cultural exchanges,it also has a greater impact on local customs.The Jiange City Wall was built in the Ming Dynasty for 10 years(1474)Jianzhou Zhizhou Mengzhang.Previously,the defense relied mainly on natural barriers.Jiange County is surrounded by mountains,and it is necessary to pass through the cracks between the two mountains.Relying on the urban terrain,the southeast is developing better and the northwest is slightly worse.With the development of the city,the types and quantity of buildings in the city have gradually increased.In the Qing Dynasty,Jiange City formed a city-level pattern with the county office as the center,residential,school,college,temple,and shop.The number of households in Jiange City has fluctuated with the change of political situation,but it has shown a gradual growth trend.The agriculture of Jiange County has always been based on the cultivation of food crops,supplemented by economic crops.However,due to production technology constraints,food production in Jiange County is not ideal for a long time,while vegetables,fruits,While economic crops such as medicinal materials are self-sufficient,they have a certain degree of external output and increase the income of the people.In the late Ming and early Qing dynasties,the war was frequent,the commercial development of Jiange City was unsustainable,and the market was closed.After the Qing Dynasty unified the country,the political situation in Sichuan gradually stabilized,and the business of Jiange City was once again active,but the overall level was low.In addition,with the stability of politics and economic development,the education of Jiange County has also made certain progress.During the Song,Yuan,Ming and Qing Dynasties,the school education of the Jiange School belonged to the stage of the temple system.Schools such as colleges and private schools were from nothing to nothing.As the starting point of the Wudoumi Road,Jiangeshan Hemingshan is one of the birthplaces of Taoism.Taoism spread earlier and has a greater impact.Many historical and cultural celebrities have emerged in the history of Jiange County,leaving a rich cultural heritage for Jiange County.After the liberation of Jiange County,the development of Jiange City has opened a new page,and it is also facing the test of a thousand wastes.Under the leadership of the party and the government,the construction of Jiange City has made great achievements,the urban area has been continuously expanded,the infrastructure has been gradually improved,and urban development has shown a good momentum.However,due to the small area of the city at the beginning of Jiange City,the overall planning time of the city is relatively late,and historical and cultural sites have been seriously damaged.Natural disasters such as droughts and floods occur frequently,which is extremely unfavorable to the development of Jiange City.After the county town was completely relocated,the old city site was seriously damaged.Therefore,only by solving the outstanding problems that have arisen in the process of urbanization,coordinating the development and protection of the Jiange City,and scientifically developing the tourism resources in the county,can we develop well and quickly.
