川西地区常见森林类型枯落物燃烧性状差异分析
Analysis of the Variation in Burning Characteristics of Litters from Different Forest Types in Western Sichuan
摘要
Abstract
[Objective]To study the burning characteristics of litters from different common forest types in west Sichuan can help assess the risk and intensity of surface fires in different forest types.[Method]Six common forest types in the western Sichuan region were selected and their litter moisture content,ash content,ignition point,dry weight calorific value(GCV),and ash free calorific value(AFCV)were measured.By using principal component analysis,the variation in burning characteristics across different forests were comprehensively evaluated.[Result]The results showed that the differences in moisture content,ignition point,gross calorific value(GCV),and ash-free calorific value(AFCV)were significant among different forest types.Through comprehensive analysis,the flammability of litters from six common forest types in western Sichuan was ranked as follows:Pinus radiata＞Pinus densata＞Pinus armandii＞Quercus semicarpifolia＞Pinus yunnanensis＞Picea asperata-Abies fabri.[Conclusion]In this study,we measured and analyzed the burning characteristics of litters from six common forest types in western Sichuan.Our study can help predict the risk and intensity of surface fires in different forest types,and provide references for fire prevention.关键词
