地形对滇西北高山松火烧迹地更新的影响
Impact of Topography on Regeneration of Pinus densata on Fire-Slash Site in Northwest Yunnan Province
摘要
Abstract
The correlations of topographic factors of the fire-slash site to the germination,density and growth status of the Pinus densata seedlings in northwest Yunnan Province were studied.The results showed that the regeneration of P.densata on the fire-slash sites was significantly influenced by the topographic factors.The aspect and the position on the slope had effect on seedling density,the gradient of the slope affected on the seedling germination time,while the elevation factor had a weak effect on seedling density.It was proposed that fire-slash site regeneration of P.densata should be adopted conditionally,which should be applied only on the downhill sites or in the flat sites.关键词
