Analysis of the physicochemical properties and flammability of the plant leaves of typical plants in Chongli District of Zhangjiakou City,Hebei Province
摘要
Abstract
[Objective]This study analyzed the physicochemical and combustion characteristics of the leaves of eight typical plants in Chongli District of Zhangjiakou City,Hebei Province,the study aimed to provide insights for assessing the risk of local forest fires and their sustainable management.[Method]Based on the distribution patterns of the typical land surface types and natural conditions in Chongli District of Zhangjiakou City,eight plant species,including Betula platyphylla,Pinus tabuliformis,Larix gmelinii,Corylus heterophylla,shrubs,herbs,Prunus sibirica,and P.sylvestris var.mongolica were selected as the research objects.Leaves were collected from pure forest segments with high vegetation coverage,and their physicochemical properties were determined.The combustion characteristics of the leaves of these eight plant species were determined by principal component analysis.The leaves were additionally categorized based on their combustion levels by cluster analysis.[Result]The combustion intensity of the leaves ranged from strongest to weakest in the following order:P.sylvestris var.mongolica,B.platyphylla,herbs,P.sibirica,C.heterophylla,P.tabuliformis,L.gmelinii,and shrubs.The leaves were classified into three categories by principal component analysis and cluster analysis,namely,the highly combustible,moderately combustible,and most easily combustible groups.The highly combustible category included L.gmelinii,P.tabuliformis,and scrub plants.The moderately combustible category comprised B.platyphylla,C.heterophylla,herbs,and P.sibirica,while the most easily combustible category included P.sylvestris var.mongolica.[Conclusion]L.gmelinii,P.tabuliformis,and shrub plants exhibited the lowest combustion propensity,thus posing as minimal wildfire hazards.Conversely,the combustion propensity of P.sylvestris var.mongolica was highest,indicating an elevated risk of wildfires.Therefore,targeted attention and preventive measures are imperative for controlling wildfires in Chongli District.The findings provide crucial evidence for predicting forest fires in Chongli District of Zhangjiakou City,and advocates the implementation of measures such as biological fire prevention and controlled burning during forestry operation.关键词
