Chinese fir plantations in the Dagang mountain after freezing rain and snowstorm disaster in 2008 were selected as the object of this study. We chose representative districts, and set up 10 sample plots, then investigated the damaged status, recovery and reconstruction techniques of Chinese fir plantation. We assessed the healthy level of the forest ecosystem after three years' recovery and reconstruction. The results showed that; (1) The total ratio of damaged Chinese fir plantation in the Dagang mountain was 51.22 % , among these damaged trees, uprooted trees accounted for 3.73 % , stem -broken trees accounted for 6. 18% , and top-broken trees occupied 41. 32 % ; (2) As for the damaged degree of Chinese fir plantation, diameter at breast height (DBH) , tree height and elevation were the predominant factors; ( 3 ) The recovery and reconstruction techniques included forest clearing and complementary planting, density adjustment, and prevention and control of plant diseases and insect pests; (4) The minimum and the maximum of the health assessment index of Chinese fir plantation ecosystem after recovery were 10.59 and 12.03, respectively, and its mean value was 11.43.%以江西大岗山2008年冰冻雨雪灾害中受灾的杉木人工林为研究对象,选择具有代表性的典型区域,设置10个样地,调查了杉木人工林的受灾情况、恢复重建技术,并对恢复重建3年后的杉木人工林进行了森林生态系统健康评价.结果表明:(1)大岗山杉木人工林的各类受损比例达51.22%,其中翻兜占3.73%,腰折占6.18%,断梢占41.32%;(2)杉木人工林的受灾程度,主要受胸径、树高和海拔的影响较大;(3)受灾杉木人工林的恢复重建技术主要有林地清理和补植、密度调整和病虫害防治等;(4)冰冻雨雪灾害后经过恢复的大岗山杉木人工林生态系统健康评估指数最小值为10.59,最大值为12.03,平均值为11.43.
