| 摘要: |
| 在风景园林规划设计中，当前使用ArcGIS作为道路自动选线工具的研究较多，但该方法在小区域内无法取得较为精准的选线结果。基于Rhino+Grasshopper平台，对Dijkstra最短路径算法、遗传算法及道路选线影响因素进行研究，构建了参数化风景环境道路自动选线模型。使用参数化设计生成的路径符合风景区低影响开发和低成本建设的原则，且路径曲线最大限度满足风景区道路极限平曲线现行规范值。构建的参数化模型可以解决所有同类型问题且便于调整和优化，为风景环境道路选线提供了新的解决方法。 |

| Abstract: |
| In the planning and design of landscape architecture, there are many researches using ArcGIS as road automatic route selection tool at present, but it is unable to achieve more accurate route selection results in a small area. Based on the Rhino+Grasshopper platform, this paper studies the Dijkstra shortest path algorithm, the genetic algorithm and the influencing factors of road route selection, and constructs the road automatic route selection model in the parameterized landscape environment. The path generated by using parametric design conforms to the principle of low impact development and low cost construction of scenic spot, and the path curve can meet the current standard value of limit horizontal curve of scenic spot road to the greatest extent. The parameterized model constructed in this study can solve all the problems of the same type, and it is easy to adjust and optimize, which provides a new solution for road route selection in scenic environment. |
