摘　　要：以广西桂林七星景区为研究区,基于遥感、地形、POI、信号热力分布差异等时空数据,选取植被、坡度、坡向、建筑物、道路、景点位置和人流密度分布作为火灾风险的评价因子,利用层次分析法、因子加权叠置分析法和自然断点法评估火灾风险,模拟传感器分布,计算并评价景区的真实建设成本。结果表明,基于多元时空属性数据的火灾监测传感器布局方法可以很好地模拟复杂地形地貌环境的景区布局,实现中高风险区的全覆盖,且考虑了硬件成本和地形可达性成本对传感器布局与火灾监测覆盖面积的影响。Taking Qixing scenic spot in Guilin,Guangxi as the study area,based on the spatio-temporal data such as remote sensing,topography,POI,signal thermal distribution difference,taking vegetation,slope,aspect,building,road,scenic spot location and pedestrian density distribution as fire risk evaluation factors,we used the analytic hierarchy process,factor weighted superposition analysis and natural breakpoint method to evaluate the fire risk,simulated sensor distribution,and calculated and evaluated the real construction cost of scenic spot.The results show that the layout method of fire monitoring sensors based on multivariate spatio-temporal attribute data can well simulate the layouts of scenic spots with complex terrain and geomorphic environment,and achieve full coverage of middle and high risk areas,and consider the influence of hardware cost and terrain accessibility cost on sensor layout and fire monitoring coverage area.
