摘要: 通过外业调查和实验室测定,利用绝对含水率和载量2个关键指标,研究了持续干旱背景下昆明西山国家森林公园的华山松、云南油杉、滇青冈、地盘松、麻栎和旱冬瓜等6种主要林型的可燃物特征。结果表明:地表可燃物、粗死木质残体的含水率最高的都为云南油杉林,分别为55.36%,40.95%,最低都为滇青冈林,分别为10.26%,10.58%,差异显著,最高与最低分别相差约5.4倍、3.9倍;载量都达到较高水平,地表可燃物载量最大为华山松林(4.53±1.11) kg/m2,最低为旱冬瓜林(2.08±0.19) kg/m2,相差约2.2倍,粗死木质残体载量最高为地盘松林为(0.94±0.16) kg/m2,最低为旱冬瓜为(0.07±0.03) kg/m2,相差约13.4倍。

Abstract: During sustaining drought from 2009 to 2012,by plots surveying in Xishan national forest park of Kunming and lab experiments and using 2 key factors including moisture content and fuel loading,the characteristics of ground fuels of six main forest types which consist of Pinus armandii Franch,Keteleeria evelyniana Mast,Cyclobalanopsis glaucoides Schottky,Pinus Yunnanensis Var Paamaea,Quercus acutissima Carr and Alnus nepalensis D.Don were studied.The results have shown that the highest moisture contents of ground fuel and coarse woody debris are Keteleeria evelyniana Mast,which are 55.36% and 40.95% respectively;while the lowest is Cyclobalanopsis glaucoides Schottky,which are 10.26% and 10.58% respectively.The highest fuel loading of ground fuel and coarse woody debris is Pinus armandii Franch and Piuus Yunnanensis Var Paamaea,which are 4.53±1.11 kg/m2 and 0.94±0.16 kg/m2,respectively,while the lowest of them are Alnus nepalensis D.Don,which are 2.08±0.19 kg/m2 and 0.07±0.03 kg/m2,respectively.

Key words: moisture content, fuel load, ground fuel, coarse woody debris, Xishan National Forest Park of Kunming
