A Preliminary Study Of Management Unit With Historic Town Organic Regeneration

China is a vast territory with many historic cities and towns,and most of the historical sites is retained in urban residents' daily life.But under the impact of large-scale and rapid urbanization in recent 20 years,historical towns disappearing at an alarming rate and fragmentation.Under the press of high economic interests,“how to achieve the balance of historical towns protection and development?” has become the urban development's urgent problem to be solved.After the 21 st century,Chinese historical towns protection gradually be institutionalized and legalized,besides,historical towns became an increasingly active part in the field of urban economic and social.All sectors of society began to realize that the value of historical towns is not only reflected in the rich material culture heritage,but also reflected in the customs,art,cooking and other non-material cultural heritage,the lively social inseparable from the people who live here,they are the source of historical towns remain vigorous.Therefore,kick all indigenous people away,simply use “corrosion prevention” to freeze the historical towns is against the natural law of development.That's why we need to insist the concept of organic Regeneration,treat the city as a living organisms,and the changes of politics,economy,culture,art,as the urban necessary metabolic processes.As Chinese urbanization process is slowing down,the situation that the government and developers leading large-scale urban renewal is change.The means of urban renewal has become increasingly diverse with longer time and more participators.From Guangzhou Urban renewal Bureau puts forward the model of “Micro Transformation”,Shenzhen comes up with “Renewal Unit” system,to “Small incremental regeneration of historical block” tested in many places,they are trying to release the renewal of land development rights,step by step to find the way that let more participators to join in.“Management unit” is a methodology based on historical towns organic regeneration concept,focus on the complexity of the form and property situation,and the urgent need of participate in urban regeneration,solve the complex problem in a simple way,propose a systematic and intensification solution of urban regeneration.Based on Conzen urban morphology analysis method and the practical experience of manage urban regeneration through unit system,multiparty system at different countries,to build management unit architecture system;to clear the context of historical towns;to achieve the trinity of protection,inheritance and development.Eventually,provide clear,distinct work platform for the urban regeneration operators.
