| 摘 要： | 在浙江九龙山国家级自然保护区选择受雪灾破坏严重的银鹊树(Tapiscia sinensis)林和基本未受破坏的银鹊树林进行研究,结果表明:①从种群径级结构来看,受雪灾破坏严重的种群,幼苗、幼树、小树数量严重不足,其数量仅为1株,相反未受破坏的样地中则低龄级个体充足;②从种群高度和冠幅来看,受雪灾破坏严重的种群中银鹊树种群高度明显低于未受破坏的种群,前者中中树和大树平均冠幅明显低于后者;③微地形、银鹊树树高和尖削度以及林分特征是银鹊树种群雪实受害严重的原因。

| Abstract: | Study was carried out in Jiulongshan National Nature Reserve on effect of snow disasters in 2008 on population structure of Tapiscia sinensis, an endemic species in China. Two plots damaged by snow disasters were chosen, and the age structure was analyzed. The result showed that in seriously damaged population(Q1), there was only one seedling, indicating a declining population. In contrast, the age structure of not damaged population(Q2) was stable with sufficient young-aged individuals. Population height a... |
