| 在风景园林规划设计中，视觉关系一直是分析研究的重要内容之一。在地形复杂的山地丘陵环境中，GIS等工具能够辅助规划师更好地进行决策。目前，GIS作为一种地理分析工具，已经被广泛地应用到多种行业的可视性分析中，但在国内风景园林规划领域尤其是线性空间规划方面，GIS视域分析的方法和考虑的因素仍然比较单一。以自贡市旅游快速路G247为例，引入累积视域、视觉幅度等多种评价参数，基于ArcGIS和ENVI平台，结合GIS工具、python编程和遥感影像监督分类解译，分别从地表类型、地形可视性和空间特征3个层次，对西南地区典型山地丘陵区域的道路景观评价和控制方式进行研究，为拓展和完善GIS技术在路径视觉关系评价规划中的应用方式提供参考。 |

| Abstract: |
| In landscape planning and design, visual relationship has always been an important content of analytical research. In a mountainous or hilly environment with complex terrains, tools such as GIS can help planners make better decisions. At present, GIS, a geographic analyzing tool, has been widely applied to the visibility analysis of various industries. However, in the field of landscape architecture planning, especially linear spatial planning, GIS view analysis methods and considerations are still relatively single. This paper takes G247, a tourist highway in the city of Zigong as an example, introducing various evaluation parameters such as cumulative field of view and visual amplitude. Based on the ArcGIS and ENVI platforms, coupled with GIS tools, python programming and remote sensing image supervised classification and interpretation, this research adopts three levels including surface type, visibility of terrain and spatial characteristics are used to study the road landscape evaluation and control methods in typical mountainous and hilly areas in Southwest China. It provides methods for expanding and improving the application of the GIS technology in linear visual relationship evaluation planning. |
