摘要: 在滇中昆明西山国家森林公园紫茎泽兰连续分布区设置样地,进行外业调查、采集样品,并在实验室测定燃烧性参数,包括活紫茎泽兰(带枝条和叶)、枯死紫茎泽兰和紫茎泽兰凋落物的点着温度、热值、灰分含量等。结果表明:枯死、活紫茎泽兰的载量不到为0.5kg/m2,凋落物的载量为(0.97±0.06)kg/m2,载量不大;枯死和活紫茎泽兰的点着温度分别为(236.7±4.8)℃,(243.4±4.8)℃,凋落物的为(281.7±1.9)℃,点着温度都很低,很容易着火;枯死、活紫茎泽兰的热值为分别为(21 075.2±8 627.2)kJ/kg和(18 527.9±913.7)kJ/kg,凋落物的热值为(16 223.2±1 257.6)kJ/kg,处于较高水平;枯死紫茎泽兰的灰分含量为(9.89±0.33)%,活紫茎泽兰的灰分含量为(4.44±1.01)%,凋落物的灰分含量则高达(17.22±5.93)%。

Abstract: Sample plots of Eupaorium adenophorum Spreng were set up,and field investigation and lab experiments were conducted for testing combustible indexes,including ignite temperature,heat values and ash content.The results showed that the fuel loads of dead and live Eupaorium adenophorum Spreng were less than 0.5 kg/m2,while the litter of Eupaorium adenophorum Spreng arrived at (0.97±0.06)kg/m2;ignite temperatures of dead,live and litter fuels were (236.7±4.8)℃,(243.4±4.8)℃,and (281.7±1.9)℃,respectively,which was very easy to ignite;heat values of dead,live and litter fuels were (21075.2±8627.2)kJ/kg,(18527.9±913.7)kJ/kg and (16223.2±1257.6)kJ/kg,respectively,which reached a high point;and the ash contents of dead and live fuels were (9.89±0.33)% and (4.44±1.01)%,while that of the litter amounted to (17.22±5.93)%.

Key words: fuel load, ignite temperature, heat values, ash content, Eupatorium adenophorum, central Yunnan province
