| 摘 要： | 锥连栎林是金沙江干热河谷仅有的几种重要天然植被之一,由于恶劣的气候环境以及长期严重的人为干扰作用,林地生境破碎化程度较高,幼苗天然更新极为困难.分析了锥连栎林更新幼苗主要生长的落叶堆积洼地、落叶堆积平地、菁沟冲积台地和缓坡草丛等4种微生境特点,并比较研究了不同微生境下天然更新幼苗生长的形态特征、生物量分配以及幼苗生存状...

| Abstract: | Quercus franchetii forest is one of the very important natural vegetations in dry-hot valley of the Jinsha River,China.Now it is very difficult for seedling natural regeneration because of serious habitat fragmentation resulting from bad climatic environment and long-term serious human disturbance.Seedlings in the Q.franchetii forest are mainly located at low land covered by litter(LLCL),flat ground covered by litter(FGCL),terrace along water ditch(TAWD) and grassland in gentle slope(GGS).To know the seedli... |
