| 摘 要： | 采用空间序列代替时间系列的方法,对阔叶林和白桦落叶松林火烧迹地生物量变化进行研究的结果表明：在阔叶林和白桦落叶松林的火烧迹地中,总生物量随着火烧后时间的延长呈增长趋势;在中、重度火烧迹地中,草本生物量、灌木生物量占总生物量的比例在火烧后15年间波动比较大,15年后趋于稳定;在轻度火烧迹地中,火烧1年后波动趋于平缓。 |
| 关 键 词： | 生物量 火烧迹地 阔叶林 白桦落叶松林 |

| Abstract: | The investigation on biomass in broad-leaved forest and the birch and larch forest at different degree of burned areas through the space sequence of time sequence method.The result showed that the total biomass of broad-leaved forest and the birch and larch forest into growing trend with time after fire.The curve of the proportion of the herbaceous biomass and shrub biomass account for total biomass was more volatile between 15 years in moderately and severe burned areas.But in light burned,the curve was ge... |
