摘　　要：通过外业调查和室内测定,获得西山国家森林公园主要可燃物的相关参数,输入BehavePlus模型,得到潜在火行为参数,以火强度大小为主要指标划分主要可燃物类型,结果表明:在坡度分别为25°和35°情形下,高强度火的林分为地盘松林、麻栎林和云南油杉林,中强度火的林分是华山松林和滇青冈林,低强度火的林分只有旱冬瓜林。研究结果可合理划分火险等级,实施科学的火管理。Through field investigation & laboratory measurements,the relevant parameters of main combustible of Xishan National Forest Park were obtained;BehavePlus model were input;potential forest fire behavior parameters were obtained;the main fuel types were divided by taking fire intensity size as the main indicator index.Result shows that:while the slope is 25°and 35°respectively,the stand with high strength are Pinusyunnanensis ,Quer-cus acutissima &Keteleeria evelyniana;the stand with medium strength are Pinus armandii &Cyclobalanopsis glaucoides;the stand with low strength is only Alnus nepalensis.The results can be a reasonable division of fire danger rating,the implementation of scientific fire management.
