人为火源森林火灾致灾因素及防控方法研究进展OA北大核心

Under the combined effects of global climate change and human activities,human-caused fire source have become the primary driver of forest fires.These human-caused forest fires exhibit widespread geographical distribution,high frequency,and strong correlation with human activities,accounting for approximately 90％of recent wildfires,thereby leading to significant ecological damage and substantial economic losses.This paper explores the causative factors and the prevention approaches for human-caused forest fires.From a spatial perspective,it examines the geographical and environmental characteristics of fire-prone areas;from a temporal perspective,it reveals the temporal distribution patterns of high fire incidence;and from a behavioral perspective,it analyzes the attributes of human activities contributing to fire ignition.Under the framework of"risk environment-risk cycle-risk source",the paper reviews the research progress on human-caused fire prevention and control in terms of quantification of causative factors,modeling of mapping relationships,and integration of multidisciplinary knowledge,analyzes their theoretical foundations,application effectiveness,and advantages and limitations in applicable scenarios.The paper also proposes suggestions for optimizing measures related to spatial deployment and behavioral intervention,and discusses the ways to promote the research by quantifying human activity characteristics and deconstructing the disaster chain of human-caused fires.The aim is to synthesize existing research findings to clarify the key factors influencing human-caused fire occurrences and the current methodologies and models,thereby providing theoretical support for refined human-caused fire management and control.
