摘要:

“以网防火”是林火管理的重要形式之一。影响林火阻隔网(FFSN)火灾防控效能发挥的因素很多。文中建立FFSN火灾防控效能评判指标体系: FFSN密度、FFSN网眼变动系数、FFSN连通度、FFSN通达度、森林消防水资源点-FFSN连通指数以及森林消防水资源点-FFSN通达度6大指标; 依此构建FFSN火灾防控效能综合评判模型。应用FFSN与森林资源矢量数量和属性数据,借助ArcGIS技术和数学方法,获取评价指标值,定量评判以广州市各区FFSN火灾防控效能评判顺序,其结果为花都林区>白云林区>增城林区>从化林区。评判结果符合实际,为林区FFSN建设与评价提供重要参考依据。

Abstract:

Forest fire separating network (FFSN) is one of the key means in forest fire management. In this paper an evaluation index system for FFSN efficiency was established, with considering related factors affecting the forest fire controlling efficiency. Those indices include FFSN density, FFSN network distributed size and so on with which, a fuzzy comprehensive evaluation model of FFSN efficiency was constructed. Fire control efficiency of FFSN in the Guangzhou forest districts was evaluated quantitatively by using the geography information system software ArcGIS which has powerful spatial analysis and statistics functions. The result showed the fire control efficiency was in a ranking of: Huadou forest area>Baiyun forest area>Zengcheng forest area>Conghua forest area. The evaluated result was consistent to the reality. This study provided an important reference for FFSN construction and its evaluation.

Key words: forest fire separating network(FFSN), fire control efficiency, fuzzy comprehensive evaluation
