摘　　要：四川攀西林区多以针叶林为主。开展不同海拔梯度下针叶林林下可燃物特性的研究对当地森林防灭火工作具有重要意义。以四川攀西地区云南松及高山松为研究对象,评估了不同海拔针叶林可燃物的特性。结果表明:海拔在一定程度上与所有的可燃物特性存在相关性,海拔可能是可燃物特性的关键影响因素之一;地上部分可燃物与腐殖质可燃物的特性在一定程度上存在相关性;可燃物干重呈现出海拔梯度上的特征,且地上部分可燃物相比腐殖质可燃物更易燃。本研究丰富了海拔梯度下可燃物的相关研究,为四川攀西地区森林防灭火工作的精细化提供理论基础。The forest areas in the Panxi region of Sichuan Province are mainly coniferous forest.It is of great significance to study the fuel properties of coniferous forest under different altitude gradients for local forest fire prevention and control.In this paper,P.yunnanensis and P.densata in Panxi region of Sichuan as the research objects to evaluate the fuel properties in coniferous forests at different altitudes.The results show that the altitude is correlated with all the fuel properties to some extent,and the altitude may be one of the key factors affecting the fuel properties.There is a degree of correlation between the fuel properties of above ground part and humus.The dry weight of fuel presents the characteristics of altitude gradient,and the above ground part is more flammable than the humus.This study enriched the related research of fuel under altitude gradient,and provided a theoretical basis for the refinement of forest fire prevention and suppression work in Panxi region of Sichuan Province.
