| 摘 要： | 通过对大兴安岭兴安落叶松火烧迹地木炭的野外调查和取样，分别选取不同来源（兴安落叶松，白桦，灌木，草本）的木炭，以及不同火烧时间（当年，1年，4年，5年）的木炭，研究不同种类木炭浸提液，以及相同种类不同火烧时间木炭浸提液对兴安落叶松种子萌发的影响。研究结果发现，不同来源、不同时间的木炭对兴安落叶松种子的萌发均有显著性的影响，但作用力的方向和大小也各不相同，这说明木炭对种子萌发的影响因素非常复杂。 |

| Abstract: | To understand the effects of charcoal after forest fire on the germination of Larix gmelinii at Great Xingan Moutains, we investigated the charcoal distribution and collected different types of charcoal produced by trees(L.gmelinii and Betula platyphylla Suk.), shrub and grass, respectively. We collected charcoals produced by different years(1, 2, 4 and 5 year) from the burned forest sites. Then, the charcoals were soaked into water at 12, 24, 48 and 96 h to obtain different charcoal solution. There were significant effects of different charcoal and different produced years on the germination of L.gmelinii seeds. However, the strength and directions of effects were randomly, and the effects of charcoal were very completed. |
