Research On Beautiful Rural Landscape Based On Real-life 3D Mode

The construction of beautiful countryside is the basic unit of the construction of beautiful China,and the construction of beautiful countryside is of great significance to promote the construction of a new socialist countryside.In recent years,some regions have achieved excellent results in the process of building beautiful villages,and the village landscape directly reflects the important contents and achievements of village construction.How to extract and analyze the landscape characteristics of these practical achievements is of great significance to the planning and construction as well as evaluation and identification of beautiful villages.The existing village landscape research methods have a series of problems such as single research dimension and lack of quantitative means.In the construction of village landscape,landscape evaluation is an essential part,but the current evaluation and analysis methods for village landscape are too limited.In response to the above problems,the research method of beautiful countryside form and color landscape based on realistic 3D model is proposed,and the quality of village color landscape is evaluated through the control analysis of beautiful countryside color landscape and ordinary countryside.This paper takes Jinzhai County of Anhui Province as the research area,selects typical beautiful villages with strong representativeness as research objects,combines UAV photogrammetry technology,constructs realistic 3D models,and uses a combination of quantitative and qualitative methods for landscape feature analysis and quality evaluation.The main preliminary conclusions are as follows:(1)The study of village morphology and landscape.The research objects are 24 provincial beautiful villages and 12 ordinary villages in Jinzhai County.Explore the differences in the form of beautiful countryside and ordinary rural landscape.Through visual interpretation and quantitative methods,the morphological characteristics and spatial sequence of beautiful villages are classified.In addition,the landscape indicators such as courtyard space ratio,road space,village intelligibility of different types of villages are summarized and analyzed,and the research results of village spatial morphology landscape based on the real 3D model are obtained.(2)Research on village color landscape.Comparative analysis of beautiful villages and ordinary villages in Jinzhai County from the perspective of color attribute and pattern.The experimental results show that the distribution of village colors is more concentrated and characterized by sub-area distribution compared with ordinary villages.The natural landscape color of beautiful villages in the Menzel color system is mainly distributed in the YR(yellow-red)-GY(green-yellow)interval,while the ordinary villages are mainly distributed in the YR(yellow-red)-BG(blue-green)interval,and the artificial landscape of beautiful villages is mainly in the medium brightness,and the color intensity is mainly concentrated in the low color intensity range.The number of color patches and color types in the beautiful countryside is smaller than that in the ordinary countryside,and the larger color patches maintain the stability of color in the beautiful countryside villages.The irregularity of color patches in woodland,grass and houses in the common countryside is obvious,the fragmentation of color landscape is serious,and the heterogeneity of color landscape is significant.(3)Quality evaluation of village color landscape.Through the evaluation of the beauty of the village color landscape,the mean value and standard deviation of the beauty of the village color are 4.13 ± 0.35,and the mean value of the beauty of the ordinary village color is 3.11 ±0.67.The mean value of the general countryside color beauty score is 3.11±0.67 The color landscape evaluation model shows that the dark green has a relatively large area,relatively concentrated distribution,tortuous green edges,low color richness,relatively large color blocks,and relatively concentrated rural color landscape has a higher beauty score.
