Abstract: According to the investigation on the Cunninghamia lanceolata forest plantation in the Jiulongshan Nature Reserve, Zhejiang Province, China, differences in resistance ability to ice and snow damage and sprouting ability of Chinese fir (Cunninghamia lanceolata) due to the severe ice and snow storms occurred between January and February 2008 were to be analyzed among different DBH, tree height, taperness and altitude. The results showed that the Chinese fir plantations at this site were severely damaged, The crown breakage and stem breakage exhibited higher proportion of the damage, while uprooting and died of freezing exhibited lower proportion. The Chinese fir possessed exceedingly strong sprouting ability, and the crown breakage plant possessed highest. Significant differences of resistance ability and sprouting ability of Chinese fir were observed among different DBH and the different tree height, the shorter trees with smaller DBH were more likely to be heavier afflicted by uprooting and died of freezing, while the taller ones with higher DBH were more likely to be lighter afflicted by crown breakage and stem breakage. The top sprouting exhibited greater proportion. The trees in the high altitude area were more heavily afflicted and the ones in midaltitude area possessed stronger sprouting ability.
