摘要:
以千岛湖29 个样岛木本植物的种子与幼苗为研究对象,分析了种子大小与种子数量的相关性,以及岛屿参 数、地形因素和土壤养分含量如何影响种子大小并作用于幼苗早期存活。结果显示:(1)物种间种子大小与种子 数量存在权衡关系;(2)种子大小对幼苗半年存活率无显著正效应,但坡向朝东、土壤碳含量低增加了种子大小 对幼苗存活率的正效应,而夏季对大种子幼苗的不利影响大于小种子幼苗;(3)幼苗高度和土壤磷含量对幼苗半 年存活率有正效应,而幼苗所在岛屿与最近岛屿的距离对幼苗存活率有负效应。本研究结果表明,千岛湖片段化 生境中种子大小和生境因素共同影响幼苗早期存活,小尺度的生境异质性增强种子大小的作用,从而影响森林更 新和群落构建。
Abstract:
During 2019-2020, 29 islands dominated by Pinus massoniana with few human disturbance were selected in the Thousand Island Lake, Chun’an, Zhejiang province to establish forest dynamic plot. In spring of 2011, 498 quadrats were built in the 29 islands for investigation of seedlings in spring and autumn from 2011 to 2015. Results showed that there was a trade-off between seed mass and seed number. Seed mass had no significant effect on seedling survival rate within half a year. The aspect and the lack of soil carbon content had positive effect of seed mass on seedling survival rate. Larger mass had greater negative effect than small mass on seedling survival rate in summer. Seedling initial height and soil phosphorus content showed positive effect on seedling survival rate, while distance to the nearest island had negative effect on seedling survival.
