基于GIS场模型的时空格局演变及关联性研究
Research on spatial-temporal pattern evolution and correlation based on GIS field model
摘要
Abstract
In view of the lack of GIS 'field' research method in spatial analysis and the real demand for strengthening the protec-tion and research of national key cultural relics.Based on the POI point elements,this paper built the spatial analysis idea of 'point-surface-body' interaction,and comprehensively applied the GIS 'field' model methods such as density field surface model,hotspot detection model,geographic information mapping and collaborative location quotient.The 'field' model method was used to extract and identify the morphology,hotspots and their scale levels of the national protection units,analyze their spatial structure,distribution pattern and spatial correlation,and make a historical and geographical review.The results showed that:① GIS field model could make up for the lack of 'field' perspective in spatial analysis,and could effectively extract,identify and express geographic elements or objects with different morphology,intensity level,extensiveness density,structural hierarchy,and spatial interactions from POI data with a small sam-ple size of large-scale scope,so as to realise quantitative hotspot patterns.② The national conservation units had the following charac-teristics.Unit cases:the location was 'dense in the southeast-sparse in the northwest',and the morphology was 'multi-axis,multi-core,multi-sheet,multi-layer' nested field shape,showing strong continuity and boundary ambiguity.The interaction of hotspots in different periods,the interaction,agglomeration and spatial heterogeneity of hotspots in different periods were obvious,and the distribu-tion of hotspot levels was inversely proportional to the degree of dispersion,presenting a tendency to the distribution of 'provincial boundaries'.The map of geographic information didn't reveal obvious and regular features of the map,and locally different levels of hotspots had formed a multifarious and complex,spatially superimposed symmetrical and digital field hierarchical structure mapping,and the differences in node connectivity were highlighted.Digital field hierarchical mapping,the global synergistic location quotient of spatial correlation was less than 1,the overall correlation and spatial interaction were weaker,the attraction degree of the existing class by the ancient class was much larger than that of the ancient class by the existing class locally,and the spatial correlation strength of the two classes on the 'north-south direction' was larger than that of the 'east-west axis'.The spatial association strength of the two catego-ries in the 'north-south direction' was greater than that in the 'east-west axis'.关键词
