Visualization Analysis Of Spatial Elements Of Chongqing Settlement Under Technical Intervention

The state attaches great importance to the protection of traditional villages and the construction of villages.It has successively proposed a series of policies such as“Chinese traditional villages” and “rural revitalization strategy”.However,due to technical constraints,the cognition of traditional villages,especially the inherent laws of traditional villages.Insufficient awareness.In recent years,the development of UAV technology,remote sensing technology,GIS,parametric design,big data and other technologies,the intervention of technology provides unlimited possibilities for the study of traditional settlements.In this study,the macro-depth DEM data of Chongqing settlement and the millimeter-scale DEM data of unmanned aerial vehicles are taken as the basic data sources.Through the comprehensive technologies such as GIS technology,parametric analysis technology and graphic visualization analysis technology,the spatial elements of Chongqing settlement are visualized and Multi-scale,multi-level and multi-angle visual analysis of geographic information patterns,ecology and land use,settlements and architectural spatial patterns of Chongqing settlements,revealing the inherent distribution of Chongqing settlement geographical distribution,settlement type,settlement texture,ecology and land use.law.The main work and conclusions are as follows:(1)Technical methods based on the visualization of settlement space elementsThe settlement information obtained by traditional technical methods is mainly two-dimensional,flat,and limited data resources.The rise of big data and the emergence of consumer-grade drones provide various possibilities for data collection.This paper adopts “active interventional” multi-level data acquisition technology;data processing technology based on “empty three operations”;data analysis technology based on “parameterization”;and “millimeter-level” DEM data through comprehensive data processing techniques.The millimeter-level orthoimage data,etc.,the integrationof technical techniques is an important means of visual analysis of settlement space elements.(2)Visualization analysis of settlement space elements under technical interventionVisual analysis of settlement geographic information at the macro level,visual analysis of settlement ecology and land use at the meso level,visual analysis of micro-level settlements and architectural space composition,visualization analysis of settlement elements at three different scale levels,for settlement space elements Visual analysis provides a more comprehensive theoretical basis.1 Visual analysis of geographic information of macro-level settlements,including settlement elevation analysis,settlement slope analysis,clustering agglomeration model analysis,settlement water system,scale of settlement within the basin,and other visual information related elements.2 Middle-level settlement ecology and land use Visual analysis mainly includes visual analysis of ecological landscape livelihoods such as settlement ecological pattern,settlement plaques,corridors,matrices,settlements,settlements,and land use.3 Visual analysis of micro-level settlements and architectural space composition,mainly including settlement groups Visual analysis of layout,settlement street structure,and main landscape nodes of settlements.(3)Visualization analysis and application of spatial elements in Chongqing settlementThrough the visual analysis of the geographical information of the settlements in the Luxi River Basin at the macro level,the laws of the distribution of macroscopic settlements are summarized,the geographical environment factors affecting the distribution of settlements and the clustering modes affecting the settlement are summarized;the visualization of the settlement ecology and land use of Hejiayan Village at the middle level The paper summarizes the law of the ecological pattern of the settlement of Hejiayan Village on the middle level,the distribution pattern of the settlement patches,corridors and matrix of Hejiayan Village,the law of the land use patterns of the settlements in Hejiayan Village,and the composition of the buildings and buildings of the Wanling Ancient Town on the micro level.Visual analysis,summed up the characteristics of the settlement group in Wanling Ancient Town,the settlement space structure of Wanling Ancient Town,and the texture of the street.
