基于GIS的林区公路路线设计

Route Design of Road Construction in Forested Area based on GIS

在林区公路建设中,传统的路线勘察方法成本高,耗时长。通过分析最佳路线的基本原理,阐述了应用ArcGIS的空间分析模块进行最佳路线选择的方法和步骤,并以某林场林区公路路线设计为例说明基于GIS的最佳路线分析的具体应用。基于GIS林区公路路线设计新方法的可行性,在很大程度上缩短了勘查中的工作量。

As the traditional road reconnaissance in forestry road construction costs a lot of expenses and long time, the paper describes the method and procedures for optimum route selection based on ArcGIS spatial analysis module according to the principle of optimum route. And a case study on route design in one of forestry farms is taken as an example to explain the detailed application further. The result shows that the new method is feasible and can shorten work amount of reconnaissance in large extent.
