冰灾后南岭五指山森林树种的受损与早期恢复
Damaged status and early recovery of tree species in Wuzhishan of Nanling Mountains, South China after the ice storm in 2008
摘要
Abstract
By using belt transect method, an investigation was conducted on the damaged status and early recovery of the dominant tree species and protected tree species in Wuzhishan of Nan-ling Mountains after the ice storm in 2008. On three belt transects of 2-7 km long and 15 m wide, a total of 2832 trees with diameter at breast height (DBH) >2 cm were recorded, belonging to 141 species of 53 families and 96 genera. The damaged rate was 73% , of which, 61% was slightly damaged. About 84% of the damaged individuals more or less recovered one year after the ice storm, but nearly 16% did not recover, died, or were dying. For the dominant tree species in Fagaceae, Lauraceae, Magnoliaceae and Hamamelidaceae, their damaged rates and recovery rates were higher. Fifteen nationally protected tree species were recorded, of which, Pinus kwangtungensis and Fokienia hodginsii were most common. Except for Cephalotaxus fortu-nei and Amentoxtaxus argotaenia, the other protected species were more or less damaged, with 59% of them died or dying. In addition, 25% of the low density species with <3 individuals suffered various damages or died. The extreme ice storm in 2008 caused serious damage to the forest trees, but most species could recover naturally by sprouting. However, the loss of some rare and vulnerable species could alter the species composition, and further, affect the community succession process in the future.关键词
