Research On Urban Development And Natural System Evolution In Huzhou

Based on the background of rapid urbanization,which lead to ecological crisis and landscape homogenization,this paper takes the natural development mechanism of Huzhou as breakthrough point,focuses on the formation of urban natural spatial pattern,combines with the historical evolution materials of urban natural system,summarizes the traditional urban development mode of natural landscape,and puts forward the scientific theory and practice basis for the protection,construction and inheritance of traditional natural landscape,which are applicable to current China’s city,so as to promote the sustainable development of urban and natural system in China.This paper through the research methods of ancient and modern literature research,field investigation,graphic analysis,from four aspects analyzes urban development and natural system evolution in Huzhou:(1)Evolution of urban development in ancient Huzhou;(2)Urban natural system in ancient Huzhou;(3)Research on urban landscape system in ancient Huzhou;(4)Analysis of the natural urban development mode of Huzhou.First,according to the historical documents,this paper combs the formation and historical changes of the ancient city of Huzhou.Then,through the research methods of urban morphology and image analysis,discusses the site changes and urban morphology evolution in different periods of urban construction of Huzhou.Next,according to the above research,this paper analyzes and summarizes the main factors affecting urban development in different stages.Secondly,this paper analyzes the elements of the natural system in ancient Huzhou,which is divided into four categories:mountains and terrain,network of rivers and lakes,the water system of inner city and human landscape.Through a detailed discussion of the contents of each part,it is concluded that the natural system of ancient Huzhou has the characteristics of multi-level spatial pattern with "the fusion of landscape city" and ecological pattern of " the link of landscape city".Thirdly,based on the research of urban construction and natural system evolution in ancient Huzhou,this paper discusses the creation of "eight views" culture and the construction of urban sight system under the coordination of landscape environment in urban natural system.Finally,through analyzing the formation and development of urban pattern in contemporary Huzhou,comparing and evaluating the ancient and contemporary urban pattern,this paper discusses the inheritance and development of modern urban planning on the basis of natural environment in ancient Huzhou.From this,we can conclude that in the evolution process of urban and natural system,it shows a spiral rising relationship.Urban development is based on the energy supply of natural system,and in the process of improvement and expansion,cities will be more effective development and utilization of the surrounding natural system.It makes the natural system evolve from pure nature to comprehensive natural resources,and to utmost respect the relationship between city and natural system is an important foundation for the future urban development.
