The invention discloses an electric transmission line disaster prevention and reduction early warning analysis platform. A fire alarm module is used for obtaining state grid mountain fire information,mountain fire patrolling information and mountain fire monitoring information; a fire early warning module is used for conducing short-term, medium-term and long-term fire early warning by combiningmeteorological factors, vegetation information, seasons, human activities and historical mountain fire information and comparing a platform early warning result with a wide area network disaster earlywarning information to correct and optimize an early warning module in time, and the fire early warning module is further used for comparing early warning information generated by a platform and information of disasters occurring actually and giving an analysis result; a mountain fire drawing module is used for drawing a mountain fire map in an automatic programming mode. The fire occurrence information and geographic information of electric transmission lines are combined organically, the influence on the electric transmission line at the specific location by a fire is judged fast and accurately, a power grid is reasonably dispatched and adjusted, and the influence on industrial, agricultural and living electricity consumption by electric transmission line faults caused by fire damage isreduced.
