中文摘要:

      目的 基于公路景观形式美价值与视觉空间感知要素，总结归纳出可视率、绿视率、空间开敞度、空间形态指数与空间信息熵5个空间参数，并对云南省思小美丽公路展开视觉景观评价，以期提升公路沿线视觉景观质量。方法 利用GoPro相机进行公路景观采集，并借助PS软件合成人眼视野范围照片作为基础评价材料，再利用GIS、OpenCV等软件对其进行空间参数维度的考量。结论 思小美丽公路视觉景观呈现出极不均衡的空间参数结构;且存在游憩服务设施配备不足、部分路段植物养护不佳，缺乏管理及沿途景观信息缺少地方特色的主要问题。基于空间参数的公路视觉景观评价是对我国公路建设转型研究的积极回应，可为今后云南省开展公路美化绿化工程提供实际参考，也可为全国美丽公路的景观规划设计提供借鉴。

英文摘要:

      The work aims to summarize the five spatial parameters of visibility, visible green index, space openness, spatial shape index and spatial information entropy on the basis of the aesthetic value of expressway landscape form and visual space perception elements and carry out visual landscape evaluation on the Si-Xiao Expressway in Yunnan Province, in order to improve the visual landscape quality along the expressway. GoPro camera was used to collect expressway landscapes, and PS software was applied to synthesize photos in the field of view of the human eye as the basic material for evaluation. With the help of GIS, OpenCV and other software, the dimensions of spatial parameters were considered. The spatial parameter structure of visual landscape of the Si-Xiao Expressway is extremely unbalanced. Some problems are found along the Si-Xiao Expressway, including insufficient recreation service facilities, poor plant maintenance in some sections, inadequate management and lack of local characteristics of landscape information along the expressway, etc. The evaluation of expressway visual landscape based on spatial parameters is the most active attempt to practice the research of expressway construction transformation in China. It can provide practical reference for expressway beautification and greening projects in Yunnan Province in the future, and can also provide reference for landscape planning and design of beautiful highways in China.
