摘要:

布局合理的森林火灾监测点能通过少量的探头数目最大化地覆盖监控范围,及时发现火灾并确定火灾位置,可以减少灾害发生。以宁夏银川市西夏区范围内的贺兰山自然保护区为研究对象,基于地理信息系统(GIS)的可视性分析方法,根据坡度、坡向、海拔对火灾发生的影响程度,对选取的20个监测点进行排序和优先布设。结果显示,合理的火灾监控点选址可以监测到67%的森林面积。通过研究分析,以期为科学合理地部署森林火灾监测点和林业管理提供决策参考。

Abstract:

The forest fire monitoring points with reasonable layout can cover the monitoring area with a small number of probes to find the fire in time and determine the fire location.Taking Helan Mountain Nature Reserve in Xixia district,Yinchuan city,Ningxia Hui autonomous region as the research object,based on the visibility analysis method of geographic information system (GIS),20 monitoring sites were selected and arranged in order and priority according to the influence degree of slope,slope direction and elevation on fire occurrence.The results show that 67% of the forest area can be detected by a reasonable fire monitoring site.Through the research and analysis,it is expected to provide a reference for the scientific and rational deployment of forest fire monitoring points and forestry management.

Key words: fire monitoring station, peak points, terrain analysis, forest fire, Helan Mountain Nature Reserve
