基于3S技术的森林防火道路规划研究

摘要

利用3S技术得到林相图的空间数据,依据森林防火道路规划的标准要求,通过给定的约束条件、规划目标以及评价条件,分析森林防火林道初始布局,考虑各种影响最优分布的指标,对森林道路进行优化分析与规划,得出最优规划图,实证分析表明此方法在道路规划中有很大的优越性.%Using the 3S technique to get the spatial data from stock map,according to the criteria of road planning for forest -fire prevention, through the constraint condition,planning objective and valuation conditions,this paper analyzed the initial geographical distribution of forest - road for forest - fire prevention. Considering all indicators affecting optimal distribution, optimizing the analysis and planning of the forest road,then it got the optimal planning map. And empirical analysis confirmed the superiority on road planning.
