| 摘 要： | 采用控制火烧的方法探讨不同季节火烧对小针茅草原的影响。结果表明:火烧会抑制丛生禾草小针茅和无芒隐子草的高生长;春季火烧使群落的盖度在整个生长季偏低;火烧减少群落地上生物量,在整个生长季中火烧处理地基本低于未烧地,春季与冬季火烧地相比,前者总体低于后者。因而火烧处理对于小针茅草原具有一定的抑制作用,尤其春季火烧较为明显,这与火烧对建群种小针茅地面更新芽的影响有关。 |
| 关 键 词： | 火烧 季节 小针茅草原 |

| Abstract: | The influence of controlled fire on Stipa klemenzii steppe in different seasons was studied.The results showed that fire can inhibit the high growth of Stipa klemenzii and Cleistogenes songorica;fire in spring can reduce community coverage in whole growing seasons;fire can decrease aboveground biomass of plant community,it was lower in burned plot than in unburned plot during the whole growing seasons.Compared with burning in winter,burning in spring was general lower.In a word,burning had a certain inhibitive influences on Stipa klemenzii steppe,especially spring burning,this maybe related to the influence of burning on regeneration buds of Stipa klemenzii on the ground. |
| Keywords: | Burning Season Stipa klemenzii steppe |
