Research On Landscape Pattern Analysis And Visualization Of Huizhou-styled Village

Huizhou-Styled Village is a typical representative of the traditional Chinese ancient village.The Huizhou-Style is the apotheosis of harmony between the Chinese ancient people and nature.Analyze Huizhou-Styled Village landscape pattern,extract imagery and visualization expression of 3D landscape have significance scientific value.This paper sampled 4 Huizhou-Styled Village as research object.Image extract,structure characteristics and landscape analysis based on rule modeling method to realize Huizhou-Styled Village landscape fast batch 3D expression and visualization analysis.This paper combined landscape pattern with 3D visualization method,effectively analyzed ecology connotation of Huizhou-Styled Village,theoretical supported the heritage,protection,planning and tourism development of Huizhou-Styled Village culture.The main research contents and achievements of the thesis are as follows:(1)Spatial characteristics analysis of Huizhou-Styled Village based on ideal ecosystem modelBased on building environment theory and psychological field theory,from the ecology aspect,this paper forwarded the ideal ecological system model of ideal living environment and macro-structure analysis method of Huizhou-Styled Village landscape.The layout and spatial structure featured edge effect,closure effect and connectivity effect of ideal ecological system model.Thus Huizhou-Styled Village spatial analysis showed a composited pattern of "mountain-forest-village-river-forest"spatial structure which is a ring structure of construction land-centered with nature scenery stereoscopic surroundings.It reflects the good ecological cycle inside the village and conforms to ideal living environment model.(2)Analysis on 3D landscape indices of Huizhou-Styled VillageThis paper extended the traditional 2D landscape indices method,overcame complex terrain deviation of traditional indices method,put up the improved measurement of patch area and circumference.What’s more,the paper analyzed the Huizhou-Styled Village layout based on improved 3D landscape indices,founding that the problems of 2D landscape indices in landscape surface morphology of mountainous areas through comparison.The Huizhou-Styled Village area and perimeter metric were underestimated,whereas the shape metric and the diversity metric were overestimated.This caused the underestimation of the dominance of forest land patches was underestimated and the overestimation of the construction land dominance of artificial patches or semi-artificial patches during analysis of landscape pattern.The Huizhou-Styled Village preserved higher stability,connectivity and aggregation in landscape type and level.The natural landscape advantages are large than human landscape.(3)Huizhou-Styled Village modeling and visualization analysis based on rolesThe complexity,rank and diversity of Huizhou-Styled Village brought problems such as modeling time and complexity.This paper applied reusable high effective village modeling method which is effective,flexible,cost-effective.The modeling mainly focus on Huizhou-Styled architectural,village component and village structure characteristic.This paper developed Huizhou-Styled Village automatic building rule set,and forward the visualization method.In the end,this study extracted Huizhou-Styled Village image and compiled relevant modeling rules,completed the 3D model of Chengkan Village,and randomly generated central and strip based 3D model.It also realized landscaped type’s nature query based on 3D model;and surface,spatial projection area and spatial measurement of distance;3D spatial analysis and application of terrain section analysis,visualization analysis,virtual roam.This paper methodologically supported the Huizhou-Styled Village image modeling,layout analysis,and culture heritage and digital protection.It extended the research area of Huizhou-Styled Village landscape.
