| 摘 要： | 种群更新对维持种群的稳定和发展具有极其重要的意义。通过野外实地调查,对不同地区乌冈栎种群的更新情况进行了分析,结果如下:1)大多数地区乌冈栎种群的幼苗结构呈倒金字塔型,说明乌冈栎种群的更新存在一定的困难;但在乌冈栎顶级群落中,由于仍存在一定数量的幼树,短期内的更新仍能继续进行;2)从乌冈栎幼苗空间分布格局来看,林窗或林缘处呈聚集分布,而林冠下呈均匀分布,这与乌冈栎幼苗生长的需光性有极大的关系;3)乌冈栎的萌发实验表明,1～2个月的沙藏处理有利于提高萌发率,而萌发过程中鼠害和虫蛀是限制出苗率的主要原因之一;4)乌冈栎种子的传播除靠重力外,啮齿类动物对它的影响最大,他们之间存在一定的权衡关系。为了提高乌冈栎种群的天然更新率,适当干扰地开辟林窗是较佳的途径。 |

| Abstract: | It is very important for regeneration of a population to maintain its stability and development.Based on the field investigation,the regeneration of Quercus phillyraeoides population in different places was discussed.The results are showed as fo11ows:(1)The pattern of population in most areas was shown with an inverted pyramid form,which means that there were difficulties for the population to regenerate;but in the climax community of Quercus phillyraeoides,the population regeneration could continue because... |
