摘　　要：山火不仅对生态系统造成损害,还严重危害了电网的安全稳定运行,成为引发输电线路故障的主要自然灾害之一。在山火预警研究方面,随着卫星网络不断成熟,借助遥感影像,选取预警指标,建立准确的预警模型,可构建完善的山火预警平台。文章分析2001—2009年历史火点数据,选取植被类型、绿度指数、高程、坡度、坡向和月份6个预警指标,利用空间分析及统计分析相结合的方法构建预警模型,对某示范架空线路沿线遥感数据进行处理,形成山火预警等级可视化地图。实现科学预测易发生森林火灾事故的地理位置,从而进行有针对性的预防。The mountain fire not only damages the ecosystem,but also seriously endangers the safe and stable operation of the power grid,which has become one of the main natural disasters causing the transmission line fault.In the research of early warning of mountain fire,with the continuous maturity of satellite network,with the help of remote sensing images,the selection of early warning indicators and the establishment of accurate early warning model can build a perfect mountain fire early warning platform.This paper analyzes the historical fire point data from 2001 to 2009,selects six early warning indicators,including vegetation type,greenness index,elevation,slope,aspect and month,constructs an early warning model by combining spatial analysis and statistical analysis,and processes remote sensing data along a demonstration overhead line to form a visual map of mountain fire warning level.To achieve scientific prediction of the geographical location of forest fire accidents,so as to carry out targeted prevention.
