摘要
现代林火管理需要在整合森林防灭火信息的基础上,对林火发生、发展、蔓延以及可燃物景观格局现状进行系统深入的分析,以期对林分可燃物进行科学合理的空间布局,并实现对林火防区可燃物未来演替格局的预测。通过对相关研究的综述分析,基于地理信息系统(GIS)平台的空间直观模型模拟,是针对把林火作为驱动因子的大时空尺度森林景观变化研究的强有力工具。提出了以林火景观生态格局为核心的研究框架,具体研究成果将直接为林火防区提供灭火策略和灭火指挥辅助决策的数源基础和定量化技术支持。
It is necessary for modern forest fire management to base on conforming forest fire prevention and extinguishing information, systematically and profoundly analyze present wildland fire behavior and landscape pattern composed mainly of forest fuel, and arrange landscape components of forest fuel reasonably. So, people can simulate the vegetation succession, and predict future fuel pattern. Through comprehensive review of previous studies on landscape pattern, forest fire and dynamic simulation, using the GIS-based spatial explicit landscape models research on forest landscape dynamic variation that driven by forest fire disturbance on large special and temporal scale is a powerful tool. At last, the article describes a research frame whose core is the forest fire landscape ecological pattern, and the specific applying outcome will offer data source and quantificational technological support on forest firefighting strategy, command and decision assistant in the forest fire prevention area.
