By plot surveying in Xishan National Forest Park of Kunming and lab experiments, using 2 key factors including fuel loading and heat value of unit area, the combustibility of coarse woody debris of six main forest types consisting of Pinus armandii Franch, Keteleeria evelyniana Mast, Cyclobalanopsis glaucoides Schot-tky, Piuus Yunnanensis Var Paamaea, Quercus acutissima Carr and Alnus nepalensis D. Don was studied. The results showed that the combustibility of CWD of Piuus Yunnanensis Var Paamaea was the strongest in the six forest types, while that of Keteleeria evelyniana Mast was the weakest. The combustibilities of Pinus armandii Franch, Cyclobalanopsis glaucoides Schottky, and Quercus acutissima Carr were.closely similar, and that of Alnus nepalensis D. Don was close to that of Keteleeria evelyniana Mast. The combustibilities of these six, CWD were in the order; Pinus Yunnanensis Var Paamaea, Quercus acutissima Carr, Cyclobalanopsis glaucoides Schottky, Pinus armandii Franch, Alnus nepalensis D. Don and Keteleeria evelyniana Mast.%通过外业调查和实验室测定,利用载量和单位面积热量2个关键指标,研究了昆明西山国家森林公园的华山松、云南油杉、滇青冈、地盘松、麻栎和旱冬瓜6个主要林型粗死木质残体(CWD)的燃烧性.结果表明,粗死木质残体燃烧性最强的是地盘松,最弱的是云南油杉,华山松、滇青冈和麻栎的燃烧性很接近,旱冬瓜的燃烧性仅微大于云南油杉,因此,燃烧性从强到弱依次为地盘松、麻栎、滇青冈、华山松、旱冬瓜和云南油杉.
