摘要：在南岭冰雪灾害受损常绿阔叶林建立4块样地,分析样地内受损树木的受损类型、径级、树种组成等因子与灾后萌条关系,结果表明:1)灾害后受损优势木72.00%以上均有萌条出现,乔木层优势木萌条率高于灌木层,为南岭地区冰雪灾害后受损森林生态系统快速恢复与重建提供保障;2)不同受损优势木萌条率存在差异,萌条率随着受损程度的增加呈增加的趋势,其中倒伏类型萌条率最高(100%),其他受损类型中灌木层金缕梅科萌条率最低,乔木层樟科萌条率最低;3)冰雪灾害后萌条特性表现出与采伐、刀耕火种后不同的规律,应做为1个特例进行研究;4)建议在我国亚热带地区森林自然干扰频发区,在人工促进恢复时多选用格药柃、小红栲和交让木等,有利于各层次结构与组成的保持。
A frozen rain and snow disaster occurred from January to February 2008 caused an extensive and varied damage to the forest ecosystems across southern China.The objective of this study is to determine the response of dominant species of evergreen broad-leaved forest to the frozen and snow disaster in Nanling Mountain.Four plots were set to analyze the relationship between sprouting and damaged types,diameter classes,and species composition.The results showed that more than 72.00% of damaged dominant species could sprout.Sprouting rate in the tree layer was higher than that in the shrub layer,guaranteeing for recovery and reestablishment of forest ecological system in Nanling Mountain.There was variation in sprouting rate for different damaged dominant species.Sprouting rate of lodged plants was the highest（100%）.In shrub layer Hamamelidaceae plants had the lowest sprouting rate and in tree layer Lauraceae plants the lowest sprouting rate.Sprouting characters of damaged species showed different patterns dependent on harvesting,slash and burn cultivation.Based on this study,we suggest that in the forests frequently subjected to natural disturbance in the subtropical China,Eurya muricata,Castanopsis carlesii,and Daphniphyllum macropodum should be selected for artificial rehabilitaton of the disturbed areas which is beneficial to keeping the stability of layer structures and species composition of the forests.
