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
