Разработана многозональная одномерная модель на основе одномерной Гауссовой модели возгорания в лесу. Решена оптимизационная задача вычисления среднеинтегральной температуры в лесу с многозональным расположением огня. С использованием гауссовой модели однозонального возгорания показано, что при одномерном многозональном возгорании возникновения зон колоколообразного возгорания средне интегральная температура уменьшается с ростом дистанции до центра многозональных пожаров. Также показано, что оптимальная функция зависимости интенсивности огня от дистанции до центра территории пожара имеет некоторый максимум в некоторой точке, вычисляемой по полученной формуле.

A multi-zone one-dimensional model based on a one-dimensional Gaussian model of forest fire has been developed. The optimization problem of calculating the average integral temperature in a forest with a multi-zone arrangement of fire has been solved. Using the Gaussian model of single-zone ignition, it is shown that with one-dimensional multi-zone ignition of bell-shaped ignition zones, the average integral temperature decreases with increasing distance to the center of multi-zone fires. It is also shown that the optimal function of the dependence of the intensity of fire on the distance to the center of the fire area has a certain maximum at a certain point, calculated by the obtained formula.
