| 摘 要： | 以长白山不同演替阶段的森林群落(次生针阔混交林、次生杨桦林和原始阔叶红松林)内设置的永久样地为基础,布设种子收集器,定期收集并鉴定其中的种子,研究了紫椴(Tilia amurensis)种子雨的时空格局及其扩散机制.结果表明:不同森林群落中紫椴种子雨均始于7月末,持续近3个月,种子散布的时间序列为双峰曲线.第一峰值出现...

| Abstract: | Seed traps were installed to collect fallen seeds in three different types of forests in Changbai Mountain to explore the abundance and spatio-temporal dynamics of seed rain of Tilia amurensis.The three forest types were Mixed forests with Coniferous and Broad-leaved species(MCB),Secondary Poplar-Birch forest(SPB) and Original broad-leaved Korean Pine forest(OKP).Results showed that the seed rains started from late July and maintained nearly three months in all the studied stands.Two peaks occurred during t... |
