The Syntactic Parsing Of The Characteristics Of Coastal Mountainous City's Spatial Morphology Evolution

With the development of urbanization process,Qingdao has gradually entered the period of rapid urban development.The urban spatial morphology is undergoing a rapid and voilent evolution,coupled with the inner city's revolution and city exterior spatial expansion,making Qingdao city space in a sharp reorganization,a single spatial development model has hindered the sustainable development of Qingdao;at the same time the constraints of mountain-sea landscape topography conditions have always been an important factor affecting urban development,leading to Qingdao has formed a development path that different from other cities.Therefore,this paper is based on space syntax technology,to study the characteristics of urban morphology in different stages of coastal mountainous terrain environment;analysis the problems faced by Qingdao city under the restriction of coastal mountainous terrain;exploring the influence of special terrain landform on urban expansion and the interaction with city.finally,taking Qingdao as an example,to establish a correct and complete coastal mountain terrain city development concept.This paper is based on space syntax theory,select the typical "strip city" space characteristics of Qingdao as a quantitative research object,in-deep explore the different periods of urban development characteristics and deep-level evolution dynamic mechanism under constraints of mountain-sea environment in the theoretical level,enrich the urban morphology theory research results;in-deep explore the interaction between the environment and urban development,to strengthen the entity environment,historical and cultural style,regional characteristics and other connotative development in the practical level,and lay the foundation for achieving the pattern of large Qingdao.First of all,the article concludes the historical evolution of Qingdao city's development,summarizes the urban development of Qingdao from three aspects of urban development,the urban conditions and the urban development history,and divides the development history of Qingdao into three typical periods,six typical stages;Secondly,combining the means of space syntax,syntactic parsing the city's development status map in different periods,through analysing integration,selection and intelligent degree,to explore the evolution characteristics and the evolution dynamic mechanism of the city under the influence of the mountain-sea environment,then using the big data to proof the analysed results.Finally,based on the above quantitative analysis to summarize the rule of urban morphology evolution and summarize the problems existing in the development of urban morphology,the paper puts forward the reasonable suggestion of sustainable development of urban morphology.Through the above quantitative analysis and interpretation of Qingdao urban morphology evolution,we can draw the following conclusions:the spatial syntactic theory is feasible for the analysis of urban form formed under the influence of special landscape environment;during the colonial period,Qingdao showed the point to block-like accumulation evolution under the shape of coastal mountain terrain,in the disorder period,Qingdao showed strip leaping evolution under the influence of coastal mountain terrain,during the leaping development period,Qingdao showed multi-center leaping forward evolution under the restrict of coastal mountain terrain.its evolution rule include the strong growth of space,weak self-organization,high complexity and multi-center group guided by strip-shaped;evolutionary driving forces include environmental,transportation,administrative planning and other factors;facing the rapid expansion of urban scale,the diversification of morphological types,the lack of microcosmic level research and the disappearance of typical urban morphology types,the paper puts forward the measures of phased medium and sustainable urban development.
