摘  要:
在GIS的支持下,建立了林火蔓延的空间背景数据库,在此基础上采用了王正非林火蔓延模型和遍历各点算法,在空间背景数据库之上,用Visual C++6.0+MapObject2.1控件技术进行了林火蔓延的动态模拟,以实现任意地点、任意气象条件下的林火蔓延动态仿真模拟,直观地掌握林火的发生、发展和蔓延的过程,以及林火蔓延的方向等。通过对模拟结果的分析得出,在模拟的过程中计算机运行比较快,模拟效果很好。

摘  要:
Under the support of GIS, a space background database of forest-fire spread was established. On the base of the space background database, dynamic simulation of forest-fire spread was achieved with Visual C++6.0+MapObject2.1control technology by means of Wang Zhengfei′s forest-fire spread model and the algorithm for traversing every point. So, dynamic simulations of forest-fire spread at any arbitrary locations or under any arbitrary weather conditions were realized. The occurrence, development and spreading process of forest-fire are more intuitive, and the spread direction of forest fires can be simulated. Analysis of simulation results shows that the simulated effect is very satisfactory because computer runs fast in the process of simulation.
