Study On The "Frame" Morphological Features Of The Ancient City Of Handan Guangfu

The development of China's historical and cultural ancient city is a metabolic evolution process,with its unique cultural atmosphere and superior spatial characteristics.At present,in the process of the transformation and renewal of ancient cities in many cities,there is often a lack of comprehensive consideration and planning guidance,resulting in the historical and cultural ancient cities have undergone great changes and comprehensive renovation in the past few decades.The ancient city of Handan,Guangfu,has been a county,canton,prefecture and county administration in all dynasties.At this stage,it has basically maintained the characteristics of the Ming and Qing dynasties,and it is one of the most preserved ancient cities in North China.In the process of the protection and renovation of Guangfu ancient city and the development of tourism,the protection and regeneration are mostly targeted at specific historical locations,which caused the phenomenon of disordered streets and lanes,uncoordinated spatial scales and destroyed the overall form of the city.This study takes the “frame” form of Guangfu ancient city as the starting point,and based on multidisciplinary cross-researches,such as architectural typology and urban morphology.After in-depth literature surveys and extensive field investigations,the“diachronic” and “ "synchronic" analysis of the "frame" form of Guangfu ancient city.In the "diachronic" research,the evolution of the "frame" form of Guangfu ancient city is carefully examined.The evolution of the "frame" form is divided into seven periods: the initial stage,the trimming stage,the stereotype stage,the development stage,the heyday stage,the decline stage,and the revival stage.In the "synchronic" research,the current situation of the "frame" of Guangfu ancient city is analyzed in detail.Through the induction and analysis of the basic information about the current situation of the ancient city,the characteristics of its "frame" are summarized according to the four aspects of roads,borders,nodes and signs.In conclusion,the characteristics of the "frame" of Guangfu ancient city are compared and summarized.This paper contrasts the "diachronic" research and the "synchronic" research of the "frame" form of Guangfu ancient city,explores theoperation and changes of its deep structure mechanism,and summarizes the morphological characteristics of the "frame" system that should be inherited and retained.It has a very active role in identifying and protecting the traditional streets and lanes of the ancient city of Guangfu,continuing the historical context of Guangfu ancient city,and tapping its characteristics.
