Optimization Of Urban Waterfront Space From The Perspective Of Periphery Theory

Openness is the essential attribute and the proper meaning of urban waterfront space.Asa system boundary connecting urban space and water environment,its openness directly affects the degree of unicom between urban interior and water environment.In the "Build sharing,under the background of" National Health ",the paper studies the openness of urban waterfront with the help of the theory of boundary shell,probes into the spatial elements that affect the openness of waterfront space,and puts forward a targeted space optimization strategy to shape moderately open waterfront space and realize the vitality remodeling of waterfront space.First,this paper expounds the necessity,importance and feasibility of the open study of waterfront space from the perspective of openness,reality and theory,and sums up the influential factors of the openness of waterfront space by combing the relevant literatures and case studies at home and abroad,as well as the theoretical core of the theory of the boundary shell--openness,look for a fit point.Secondly,by explaining the basic characteristics,expression mechanism and the intrinsic relation between the constituent elements and the boundary shell parameters and the open calculation of the boundary shell,the boundary shell description of the waterfront space openness is described: The Urban waterfront space contains the shape boundary shell,the functional boundary shell,the traffic boundary shell,the landscape boundary shell,the space boundary Shell 5 multidimensional boundary shells,As well as the Shore line shape,building function,road area,landscape corridor width,the width of the building,such as 13sub-boundary shell,in order to establish a waterfront space open Space Evaluation Index System.Thirdly,the paper constructs the test model of the open boundary shell of waterfront space,which is qualitative and quantitative analysis of the openness of the elements of waterfront space,and obtains the spatial characteristic evaluation of the open space of the waterfront;the second is to analyze the characteristics of the citizens ' activities through the investigation of the citizen's activity data.The validity of the spatial constitutive factor hypothesis is checked by the non spatial characteristics of the citizen's activity intensity.Then,the test model is introduced into Dalian Heishijiao-star Gulf Coastal space for empirical research,the openness of the research area is qualitatively,quantitatively evaluated and compared,the open problem of waterfront space is identified,the key factors affecting openness are determined,and the direction of the optimization strategy of waterfront space is pointed out.Finally,from 5 aspects of form,function,traffic,landscape and space,the optimum principle and optimization strategy of waterfront space are put forward.including "water-green" orientation principle,the 5 principles of multidimensional blending principle,level gradual change principle and so on,such as the harmonious shoreline shape of human water,the height control of falling by layer,the function mixing of gradient changing,the traffic organization of decreasing rank,the blue-green system of network connection,the open architecture interface and so on,10 optimization strategies.
