The invention relates to a forest fire detection algorithm, and particularly to a forest fire detection algorithm and a system based on MODIS remote sensing images, and a storage medium thereof. According to the mountain fire detection algorithm, band radiation values of different channels are utilized, brightness temperature conversion is carried out according to a Planck formula, calculated hotspots are filtered, hot spots with abnormal temperature are obtained, real fire points are screened out through vegetation indexes, and the mountain fire detection algorithm can be used for fire prevention and disaster prevention in remote mountainous areas, and national property and natural resources are protected. 本发明涉及山火检测的算法，尤其为一种基于MODIS遥感影像的山火检测算法、系统及其存储介质，所述的山火检测算法在于利用不同通道的波段辐射数值，根据普朗克公式进行亮温转换，对计算出的热点进行过滤，进而得到温度异常的热点，再利用植被指数筛选出真实火点，本发明可用于偏远山区的防火防灾，保护国家财产和自然资源。
