摘　　要：针对高压架空输电线路的智能优选,研究了选线的多种影响因素及其量化方法,设计了一种变分辨率网格数据模型,并结合GIS的地形分析和空间分析,提出了顾及诸多因素的最短路径选线算法,在此基础上,构建了智能选线系统。实验分析表明,智能选线系统选出的线路符合要求,而且其速度明显优于人工选线,为送电线路选线提供了科学依据。For the smart preferred selection of high-voltage overhead transmission route, this paper studies a variety of factors as well as their quantitative methods about route-selection and designs a variable-resolution-grid data model. Taking so many factors into account, we propose a shortest path algorithm combining the terrain and spatial analysis of GIS. Based on it, the smart route selection system is constructed. Experiments show that the route selected through the system can meet the requirements. More importantly, its speed is superior to manual route selection. It offers a scientific foundation to the choosing of delivering electrical wire.
