昆明西山森林公园主要林型地表可燃物的潜在燃烧性

Study on Potential Combustibility of Ground Fuels in Kunming Xishan National Forest Park

通过外业调查和实验室测定,以单位面积热量为关键指标,研究了昆明西山国家森林公园的华山松、云南油杉、地盘松、麻栎和旱冬瓜5个主要林型地表可燃物的潜在燃烧性。结果表明,地表可燃物潜在燃烧性最强的是华山松,其次为地盘松,最弱的是旱冬瓜,云南油杉和麻栎的潜在燃烧性很接近。5种林型地表可燃物的潜在燃烧性从强到弱依次为华山松、地盘松、云南油杉、麻栎和旱冬瓜。

Through field investigation and lab test,using the heat per unit as the key factor,this paper studied the latent combustibili-ty of ground fuel of 5 main forest types of Pinus armandii Franch.,Keteleeria evelyniana Mast.,Piuus Yunnanensis Var Paamaea, Quercus acutissima Carr.,and Alnus nepalensis D.Don.The results showed the one had the potential strongest flammability was Pi-nus armandii Franch, followed by Piuus Yunnanensis Var Paamaea, the one had the smallest flammability was Alnus nepalensis D.Don,while Keteleeria evelyniana Mast.neared Quercus acutissima Carr.The potential combustibility from strong to weak was as following：Pinus armandii Franch,Piuus Yunnanensis Var Paamaea,Keteleeria evelyniana Mast,Quercus acutissima Carr,and Alnus nepalensis D.Don.
