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。
通過外業調查和室內測定,穫得西山國傢森林公園主要可燃物的相關參數,輸入BehavePlus模型,得到潛在火行為參數,以火彊度大小為主要指標劃分主要可燃物類型,結果錶明:在坡度分彆為25°和35°情形下,高彊度火的林分為地盤鬆林、痳櫟林和雲南油杉林,中彊度火的林分是華山鬆林和滇青岡林,低彊度火的林分隻有旱鼕瓜林。研究結果可閤理劃分火險等級,實施科學的火管理。

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.
