摘　　要：合适的视觉感知区位是获得良好景观体验的必要条件,但GIS视域计算结果对可视区位与景观语义之间可视关系的表征能力不足,难以进一步开展视觉景观资源的深度价值挖掘。论文基于已有景观视觉感知计算的理论与实践成果,提出并设计了面向线性文化遗产的景观视觉感知区位信息模型(landscape visual perception location model,LVPLM),基于NetCDF多维栅格数据结构建立了LVPLM数据集的组织方法及其应用逻辑。LVPLM数据集通过二维地理坐标维度表达视觉感知区位,通过语义特征点编码维度表达目标景观语义信息,进而建构视觉感知区位与景观语义之间的可视关系,实现了目标景观、感知区位和可视状态的信息集成。同时,设计了“钻取”“切片”“切块”三种LVPLM数据集应用模式,为多模式景观视觉感知信息挖掘与分析奠定了基础。论文选择长城线性文化遗产景观资源开展实证研究,建立了古北口长城LVPLM数据集,并通过实地调研勘测采集视觉对照验证数据,评估了数据集的基本可信度,初步证明了LVPLM模型的可行性与应用价值,也为长城国家文化公园高质量建设提供了新的数据资源。Appropriate visual perception location is a necessary condition for marvellous landscape experience,and rich visual perception spatial information resources will be helpful for exploring the overall perception of beautiful places.Linear cultural heritage not only contains rich resource value and profound cultural heritage assets,but also has important values in the attributes of visual landscape resources.However,the ability of the GIS viewshed computation results to characterize the visual relationship between the visual location and landscape semantics is insufficient for further carrying out the deep value mining of visual landscape resources.Based on the existing methods of landscape visual perception calculation,this study designed the landscape visual perception location model(LVPLM)for linear cultural heritage,and developed the organization method and application logic of the LVPLM dataset based on the NetCDF multidimensional raster data structure.The LVPLM dataset expresses the visual perceptual location through the two-dimensional geographic coordinates and the semantic information of the target landscape through the semantic feature point coding,and then constructs the visual relationship between the visual perceptual location and the landscape semantics,and realizes the information integration of the target landscape,the perceptual location,and the visual state.This study also designed three application modes of the LVPLM dataset,namely"drilling","slicing",and"dicing",to lay the foundation for multi-modal landscape visual perception information mining and analysis.This study selected the linear cultural heritage landscape resources of the Great Wall for empirical research,established the LVPLM dataset of the Gubeikou Great Wall,and collected visual comparison verification data through field investigation and survey,evaluated the basic credibility of the dataset,initially proved the feasibility and application value of the LVPLM model,and also provided a new data resource for the high-quality constructi
