摘要(Abstract)：
根据广元市利州区重点林区林火阻隔系统现状,分析了其目前存在防火树种单一、林分结构简单、野外火源复杂、生物阻隔带密度低等问题,并提出了提高阻隔网络密度,以防火林带建设为重点的对策。同时对防火林带网络等级、防火树种选择、防火林带结构与配置等问题进行了初步探索。防火林带分为2级来建设,根据自然条件因地制宜,合理布局,明显提高阻隔网络密度,阻隔网络分布更均匀,构建成一个新型的森林防火阻隔网络,真正达到提高利州区森林防火综合保障能力、减少森林火灾隐患的目的。
According to the status quo of forest fire barrier system in key forest areas in Lizhou,the current problems were analyzed such as single tree species,simple stand structure,complex outdoor fire source and low-density biological barrier zone. The countermeasures were put forward including desification of barrier network,and establishment of Forest Belts. At the same time,the network level of fireproof forest,tree species selection,structure and configuration of fireproof forest belts were explored. The fireproof forest zones were divided into two levels for building. The new fire prevention forest network zone was designed according to the local conditions and reasonable layout,by obviously mproving the density of the barrier network and the more even distribution of the obstructing network,so as to truly improve the comprehensive forest fire protection capability in Lizhou District,and reduce the hidden danger of forest fires.
