| 摘 要： | 本文揭示了红松原始林卫生清理后,绿色草本植物数量增加了59.1%,矮小灌木数量下降了50.95%,枯枝落叶层含量下降了24.58%。卫生清理后4年和14年,林内气温分别升高了6.0%和1.2%,相对湿度分别下降了4.26%和5.32%。这表明卫生清理后,绿色草本植物数量的增加和温度的变化使火险等级提高,而小灌木、枯枝落叶层和5种清理木的减少降低了大火和树冠火的可能性。

| Abstract: | The paper concerns in virgin korean pine forest, after sanitation cutting, the herb increases 59.1%, the shrub decreases 50.95%, the litter decreases 24.58%. After 6 and 14 years of sanitation cutting, the atmospheric temperature in the forest rised 6.0% and 1.2%, the relative humidity in the forest declines 4.26% and 5.32%. These results explain that the increase of the number of the herb and the change rising the fire danger class, the decrease of the number of the shrub and clearing all died trees in the forest will decrease the possibility of the big fire and the forest crown fire. |
