摘要：The effect of terrain on mass and heat transport of smoke plume has been neglected for a long time. A novel manner of investigating it has been proposed by integrating terrain with spatial position of smoke plume by means of Gaussian distribution. Based on unique features of digital elevation model and satellite imagery, several necessary parameters to calculate distribution of mass and heat being carried by smoke plume were capable of being obtained. The results of modelling have effectively indicated some phenomena which have not been discovered and reported. The new approach of being expressed by geomorphologic parameters is useful to not only understand how mass and heat transport of smoke plume are affected by terrain but also estimate how mass and heat impact upon the vegetation closed to burning spots. The relation between smoke plume and burning zone in mass and heat diffusion has been closely correlated.
