摘要：南岭是广东省生物资源、生物基因最丰富的宝库。2008年1—2月份,南岭遭遇到几十年甚至百年一遇的特大雨雪冰冻灾害,给森林生态系统造成了极大的破坏,使南岭林区位于海拔500—1000 m之间的林木雪折、倒伏及包括昆虫在内野生动物的大量死亡。林地清除风倒木和粗大的树技,树木园内基本清除地面各种覆盖物,作为森林生态修复与重建的最重要措施,此措施使冰灾后形成的大量林窗很快萌生各种植物,从而改善了林分结构,使森林生态系统得到修复和重建,经3年的恢复期,林分及其凤蝶多样同步获得恢复,也使生物多样性比冰灾前更为丰富,树木园内凤蝶种群数比冰灾前2年平均值增加144.44%,种群密度比冰灾前2年的平均值降低4.62%;500—1902 m灾后林区调查,3年后凤蝶种群数比冰灾当年增加为156.25%。因此,此研究结果然说明冰冻灾害后只要及时对原始林采取森林生态的恢复措施,不仅不会导致种群的灭绝,而且还有可能丰富生物多样性。
Nanling has the most abundant biological resources and biological gene pool in Guangdong Province of China. It suffered from a hundred-year return period snow disaster in early 2008, which caused severe damages to its forest trees grown in the range of 500-1000 m above sea level （a.s.1） and the associated insect fauna. In order to study the diversity restoration of Papilionidae species, investigations were made in some forest stands located at 500-1000 m a.s.1 and the Nanling Arboretum where all damaged plants were removed as a means of ecological restoration immediately after the occurrence of the snow disaster. Results showed that after three years of restoration, the diversity of forest stand structures and Papilionidae became much richer. The number of Papilionidae populations in the arboretum increased by 144.44%, while the population densities decreased by 4.62 %. The number of Papilionidae populations in the forest stands increased by 156.25%. This study implies that artificial restoration of damaged forest ecological systems will not lead to the species extinction, but probably lead to enrichment of the biological diversity.
