| 摘 要： | 从火烧对内蒙古锡林郭勒草原大针茅种群的影响着手，用控制火烧的方法探讨了不同火烧处理对大针茅种群的生态效应即火烧可以明显地降低大针茅的生长高度，减少其地上生物量，而其密度值的升高则是由于火烧导致大针茅的植丛分裂、增加了其小丛数量所造成的结果，这与其单丛干重的降低是一致的。总的来说，火烧对大针茅种群的生长发育具有明显的抑制作用。

| Abstract: | With the method of prescribed burning, the influence of burning on S. grandis population in Inner Mongolia steppe was studied. The results showed: fire can obviously decline its height growth, decrease its aboveground biomass, and increase its density, which was resulted from the plant thicket being broken up by fire and increased number of small thicket. It accorded with decreasing of dry weight per thicket. In generally, fire could produce a negative effect on the development of S. grandis population. |
