Location Selection Methods of Mountain Forest Fire Monitoring Points Based on Terrain Analysis

doi:10.13466/j.cnki.lyzygl.2020.02.020

Abstract

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
