摘要

火灾是森林中毁灭性的危险事件,对资源、生物多样性、经济、动物生命产生负面影响,并使人类处于危险之中。本研究的目的是利用地理空间技术确定约旦面临森林火灾风险的地区。研究区域从死海向北延伸50公里,向东延伸15公里。森林火灾危险区地图是根据六个因素绘制的:土地覆盖等级、地形、与居民点的接近程度、海拔、坡度和与道路的接近程度。所有的因素都是根据它们的火灾敏感性或引起火灾的能力来选择的。在本研究中,利用模糊逻辑和层次分析法(AHP)的土耳其模型将该地区分为从极低到极高的五类风险。根据调查结果,大约12.12%的研究区域被划分为极低风险,25.54%的研究区域被划分为中等风险,12.84%的研究区域被划分为极高风险。在过去的十年里,这张地图已经通过民防档案中的数据证实了以前发生的火灾。这一结论对于了解易受火灾影响地区的地理分布非常有用。研究发现,将层次分析法和模糊逻辑相结合的GIS方法是对此类地图进行评估的有效工具。

AHP and fuzzy logic geospatial approach for forest fire vulnerable zones
Fires are devastating risky events in forests, having a negative effect on resources, biodiversity, economics, animal life, and putting people in danger. The goal of this study is to use geospatial techniques to identify areas in Jordan that are at risk of forest fires. The research area extends 50 kilometers north and 15 kilometers east from the Dead Sea. The forest fire risk zones map was developed using six factors: land cover class, aspect, proximity to settlements, elevation, slope, and proximity to roads. All of the factors have been selected based on their fire sensitivity or capacity to cause fire. In this study, a Turkish model with fuzzy logic and Analytical hierarchy analysis (AHP) was utilized to classify the area into five categories of risk ranging from very low to very high. According to the findings, approximately 12.12% of the study area is classified as very low risk, 25.54 % is classified as medium risk, while 12.84% is classified as very high risk. Over the last ten years, the map has been confirmed by prior fire occurrences using data from civil defense archives. This conclusion was very useful in gaining an understanding of the geographical distribution of fire-vulnerable zones. The research found that the GIS approach combined with AHP and fuzzy logic is a useful tool for estimating such kinds of maps.
