Road planning for a scenic environment should not only comprehensively research many factors such as landforms, vegetation, water bodies, etc., but also pay due attention to ecology, function, reasonable engineering workload, aesthetic requirements, etc., and is therefore a multi-object systematic project. The parameterization method used in this paper provides a reliable scientific basis for road planning for a scenic environment, being more methodical, accurate, efficient and practicable in comparison with traditional methods of line selection based on experience. For this research, a road planning algorithm based on the ArcGIS software platform is used to construct a model of parameterized road planning for a scenic environment, taking as an example the Northern Area of Niushou Mountain Scenic Spot, Nanjing, China
