Study On The Spatial Identification Based On Network Semantics And Space Syntax ——A Case Study Of Renmin South Historical District

Historical and cultural blocks carry fragments of historical changes and cultural memory for urban development,and are also the epitome of a city’s sustainable social and economic development in a certain period of time.The unique culture in the city breeds the unique life scene and spatial environment.Increasingly importance has been attached to the protection and renovation of the regional culture of the urban city,so that the renewal and construction of historical and cultural blocks is regarded as an important way to build a unique cultural carrier.The important perceptual source of the block lies in the identification and imageability in the spatial environment it depends on,which is affected by both the spatial structure of the block and the rhythm of user behavior and activity.At present,the protection and renewal work under the local construction has encountered various difficulties,which has buried the personality and characteristics of the block in the wave of commercialization and urbanization,making the spatial identification of historical and cultural blocks an emphasis of renovation and improvement.In the Internet society,people’s daily life has been deeply penetrated by new media,which not only subverts the way people perceive and experience space,but also changes the generation mechanism of urban imagery.At the same time,it also develops a new research direction for the spatial cognition and spatial organization of historical and cultural blocks.this paper firstly reviews the proposal and development of the concept of identification,sorts out the relevant core theories,externalized application methods and research methods of spatial cognition,and summarizes two aspects that affect spatial cognition-the principles and methods of network media and space syntax,and clarifies the interaction mechanism between the two and space.It is pointed out that the research on the cognition and identification of historical blocks by the combination of network semantics and spatial syntax is still in its infancy,lacking systematic research and practical demonstration.Based on this,the network semantics and spatial syntax introduced and used in this paper is a new way of combining social and humanistic characteristics with spatial network relationship analysis.In addition,taking the Renmin South historical and cultural block of Guangzhou as an example,the spatial identification of historical block is analyzed from three different levels and perspectives: the macro-city network structure,the spatial form of the meso-block,and micro-block space nodes.Summarize the spatial characteristics and existing problems of identifiable features,and explore the causes behind.Finally,this paper summarizes the application strategies and research conclusions of the network semantics combined with spatial syntax in the demonstration of historical and cultural blocks.At the same time,it reflects on the problems that have arisen in the planning of historical blocks at the current stage,and discusses the strategies to optimize the identification of space from the two aspects of overall optimization and targeted improvement.
