| 摘 要： | 林火行为具有时间和空间特征,利用DEM(Digital Elevation Model)对林火行为进行3维模拟是一个很有前景的研究方向。本研究利用ArcView实现DEM数据源的提取、模型转换,通过林相图和地形图的配准,将影响林火蔓延的可燃物因子与DEM结合,进行效果图显示,为林火行为的3维模拟进行了有益的实践。

| Abstract: | Fire behaviors have spatio-temporal features.Using digital elevation model to simulate three-D display of fire behaviors has good prospect.The paper uses ESRI Arcview 3.0 to extract DEM data and performs model transformation.Then by means of registration of topographic map and forest map,the paper introduces how to operate overlay and evaluate factors that influence fire spread and display the effect pictures. |
