A Study On The Spatial Cognition Of Urban Village Based On PPGIS

A correct knowledge of the understanding of the living space of the urban village residents is of great significance for the transformation of the urban village.But how to capture people's cognition and values is difficult,and the concept of PPGIS provides a way to capture spatial qualitative data.This paper learns the foreign PPGIS concept and takes the pilot project of Duishan Village in Jimei District of Xiamen as an example to explore the methods and effects of PPGIS applied to capture the spatial cognition of residents,and provide suggestions for the transformation for urban villages.In terms of purpose,this paper is to explore the potential problems that may be encountered in the reconstruction or redevelopment of urban villages,and explore the feasibility of applying the PPGIS method to the spatial type of urban villages;the theoretical level borrows spatial cognition,landscape value and community attitudes and conflicts.Relevant theory;method level uses PPGIS concept design research process to capture the spatial cognition of three different types of residents in the mountain village,including the type of spatial value that residents can perceive and the attitude of spatial transformation,implemented in the form of point data.At the specific location,the GIS spatial analysis method is used to visualize the sp atial value of the mountain village in the residential level and reconstruct the conflict location,which provides guidance for the spatial transformation strategy of the mountain village.Firstly,the article summarizes the research background,defines re lated concepts,proposes the research purpose,significance and method,and introduces the research ideas of this paper.Then introduces the basic theory and summarizes the development history and application status of PPGIS.According to the specific situation of the study area,the PPGIS theory design is applicable to the acquisition process of the spatial cognitive data of the Duishan village.Finally,the acquired location-related information is entered into the GIS software in the form of points for analysis,and the local residents in the village are visualized.The spatial distribution of different cognitions of foreign operators and migrant workers reveals its connotation and significance.Finally,it summarizes the advantages and disadvantages of PP GIS applied in this research area,and discusses the possibility of spatial development of mountain villages and prospects for subsequent research.
