基于GIS的主干光缆路由敷设条件评价研究

GIS-Based Research on Installation Condition Elevation of Trunk Optical Cable Routing

利用GIS技术以及ArcGIS等GIS专业软件,结合相关主干光缆路由敷设线路设计理论,以江苏省灌云县城区为试验区,试图提出一套基于GIS的主干光缆路由敷设条件评价方法和流程。首先,总结出影响主干光缆路由敷设线路选择的因子并进行量化;然后,结合利用专家打分法得到的影响因子权重计算出总的作用分值并生成最终评价结果。结果表明:利用GIS空间分析技术能够比较有效地进行主干光缆路由敷设条件评价,其结果可以为主干光缆敷设线路设计等提供参考。

Using GIS technologies and professional GIS software such as ArcGIS,and combining relevant theories of installation line design of optical cable network,this paper uses the downtown area of Guanyun county in Jiangsu province as the study area and tries to propose a set of installation condition elevation approaches and procedures for trunk optical cable routing.First,the factors influencing the route choosing for the installation of trunk optical cable routing were concluded and quantified,then,with the weights of the influencing factors concluded through expert scoring,the total function values were calculated and the final elevation results were generated.This study indicated that：application of GIS spatial analysis techniques can effectively conduct evaluation of installation conditions of trunk optical cable routing,whose results can provide reference for the installation line design of trunk optical cable routing.
