摘　　要：云南省独特的地理地貌以及多变的气候因素,造就了云南省森林火灾易发且发展迅速的特点。针对云南电网范围内架空输电线路以及电网设备可能遭受的森林火灾问题,开展林火蔓延研究,重点突破运用Rothermel模型和惠更斯原理相结合的方法对林火蔓延进行实时模拟,在此基础上,运用ArcGIS的图形处理和空间分析能力,对蔓延过程进行图形化显示,为电网开展一次设备山火风险防控工作提供有力支撑。The unique geographical features and changeable climatic of Yunnan Province make the forest fire prone,frequent and develops rapidly.Aiming at the problem of forest fire that may be suffered by overhead transmission lines and power grid equipment in Yunnan Province,the research on forest fire spread was carried out,and the method of combining Rothermel model and Huygens principle was mainly used to simulate forest fire spread.On this basis,the powerful graphic processing capabilities and spatial analysis capabilities of ArcGIS are used to graphically display the spread process,providing a strong support for the power grid to carry out the risk prevention and control work of mountain fire.
