| The strategy of rural revitalization and the construction of harmonious rural areas have put forward higher requirements for the quality of rural environment.However,the modern construction method overly pursues speed and lacks respect for the original landscape elements of the village,which damages the core of rural spirit,eliminates the constraints of village sentiment,and blurs the characteristics and style of rural landscape.Before the construction and development of rural landscapes,a comprehensive evaluation of the visual quality of rural landscapes helps to clarify the advantages and disadvantages of landscape features,thus formulating more scientific and reasonable strategies for optimizing rural landscape development and planning landscape structures according to local conditions.The combination of evaluation and optimization can effectively promote the beautification of rural living environment and the development of rural tourism industry,drive rural revitalization,and build livable and beautiful villages.This study combs the research status of the related concepts such as landscape visual quality evaluation and rural landscape,and from the perspective of geographical characteristics and aesthetic characteristics of landscape resources,selects the ASG comprehensive method that combines AHP analytic hierarchy process,SBE scenic beauty and GIS spatial analysis as the research method of landscape visual quality evaluation,evaluates and analyzes the landscape visual quality of Baotaba Village in Kaijiang County,and then outputs the village landscape optimization strategy.The main research results of the paper are as follows:1)Divide the village into 14 landscape evaluation units according to the category of landscape feature elements.Based on the current situation of the village and the summary of previous research,establish an AHP evaluation structure based on objective geographic information quantitative analysis combined with subjective preference qualitative analysis.Use landscape visual beauty,landscape visual absorption,and landscape visual sensitivity as the evaluation criteria layer for landscape visual quality,and set 9 specific evaluation indicators such as public visibility below the criteria layer,And by assigning weights to the indicators through expert scoring,a visual quality evaluation index system for the landscape of Baotaba Village was constructed.2)Collect geographic information data,landscape feature resource images,and other data of Baotaba Village for various indicators,use GIS spatial processing technology,SBE questionnaire survey,and other methods to complete the visual quality evaluation of Baotaba Village landscape,and calculate the visual quality scores of each evaluation unit in the village,From high to low,they are Unit 13(4.63)>Unit 2(4.44)>Unit 3(4.25)>Unit 1(4.19)>Unit 14(3.44)>Unit 5(2.87)>Unit 7(2.75)>Unit 4(2.49)>Unit 8(2.19)>Unit 9(2.01)>Unit 6(1.87)>Unit 12(1.75)>Unit 10(1.38)>Unit 11(1.38).The top two feature types in terms of quality are paddy landscapes dominated by grid fields and lotus ponds.3)On the basis of the total score,a three-dimensional coordinate system is established based on the average score of the three criteria layers of landscape visual sensitivity,visual absorption,and visual beauty.The 14 evaluation units of the village landscape space are further divided into 8 different types of visual quality level areas,namely core construction area,detail optimization area,key renovation area,natural development area,emergency improvement area,maintenance protection area,and reserve development area.Based on the advantages and disadvantages of the landscape feature type units in the region at the three major criteria levels,propose landscape optimization management strategies for each region from the perspectives of landscape construction feasibility,development potential,natural and cultural aspects,to achieve clear priorities and distinctive features,and comprehensively improve the overall visual quality of the village landscape from multiple perspectives. |
