Optimization Strategy Of Spatial “island” Phenomenon In Historical Areas Based On Network Analysi

Historic areas are the product and result of specific natural,social and cultural influences,and the existing historic districts in various places generally seem to have systematic,diverse,regional and cultural characteristics.The historical area comprehensively carries the history,traditions,regions and customs of a region,and its protection and development have always attracted the attention of scholars in the fields of architectural history,cultural relics protection and urban planning.However,due to the static,fragmented and focusing on the protection concept of physical units in the past,traditional neighborhoods with high cultural value have not been able to look at the problem from the connection of the spatial network between physical units,nor can they adopt a systematic perspective to look at the problem at all levels of the system,so it is difficult to form a protection method of the system as a whole,resulting in the phenomenon of spatial "islands" at the individual levels,blocks,areas and other levels caused by the rupture of function,line of sight,context and style in the development of historical lots.At present,the spatial syntax and other software based on spatial network modeling and analysis provide a tool basis for the overall analysis of various typical "island" phenomena in historical lot protection and systematically solve the "island" problem in historical lot protection.From the perspective of the system as a whole,combined with the investigation of a large number of historical and real data,this paper deeply analyzes the characteristics of the natural environment,society and humanistic spatial network of the historical area of Jinan commercial port area,and uses spatial syntax as an auxiliary tool to analyze the spatial causes of the "island" phenomenon in the protection of the commercial port area,in order to form a systematic method to improve the phenomenon of "island" in the historical area from the macro,meso and micro perspectives,and promote the transformation of the protection of historical location from focusing on entities to focusing on context.Firstly,on the basis of the existing research results of historical lots and spatial networks by domestic and foreign researchers,this paper reflects and comments on the current situation faced in historical lots,and clarifies the main content,research objects,research methods and overall framework of this study.Then,the system theory and space syntactic techniques involved in the construction of historical spatial networks are analyzed.The spatial network of historical locations is structured from the three network levels of macro,meso and micro,and the three network levels of historical and cultural spatial network,social communication spatial network and natural environment spatial network,and the relationship between each level is analyzed.On this basis,taking the historical lot of Jinan Shangbu District as an example,the key elements and performance characteristics of each spatial network level in the historical lot are analyzed,and the spatial "island" phenomenon in the historical lot is examined in the cultural,social and natural environment spatial networks,and its existence characteristics are analyzed,which provides a basis for the optimization strategy of the spatial "island" phenomenon in the historical lot.Finally,aiming at the construction of the spatial network of the historical area of the commercial port area and the performance characteristics of the phenomenon of spatial "island",combined with its protection regulations,and based on the principle of system optimization,an optimization path from whole to part,from node to connection,and from entity to fiction is proposed.Specifically,from the macro,meso and micro levels,the optimization strategy of the "island" phenomenon of historical location space dominated by historical location to urban style,from material space to system context,and from building unit to cultural atmosphere is proposed.From the perspective of the system as a whole,it provides scientific and systematic solutions to the practical problems encountered in the process of historical lot protection and development.
