摘要：以广东乐昌十二度水省级自然保护区内严重受损天然林为对象,研究冰雪灾害对该区域天然次生林建群种的影响。结果表明:1)该区森林建群种以甜槠、南岭栲、小红栲、雷公青冈、冬青、虎皮楠和交让木为主,具有典型的地带性植被分布;2)灾害对冬青损害最轻,虎皮楠损害最重,南岭栲、甜槠、小红栲、雷公青冈等栲类种和交让木损害居中;3)建群种各受损类型中胸径1.0～5.0cm以倒伏、压弯和正常类型最多,5.1～10cm以断干和翻蔸类型最多,15.0cm以上以断梢最多,10.0～15.0cm在各受损类型受损最低;4)海拔和坡度对不同的建群种受损程度影响不同,但在一定的范围内地形因子对林木严重受损率无影响。
To understand the degree of the disaster damages to Castanopsis forests in Yangdongshan Shierdushui Provincial Nature Reserve,Lechang County,Guangdong Province,four 50 m×30 m sampling plots located from 700 to 1 000 m of elevation were stablished. Species composition and dominant species in the community were investigated in April and November,2008. The effects of the frozen rain and snow disaster on the communities were assessed by counting the numbers of plants in damaged modes of dominant species and different classes of diameter at breast height （DBH）, and the relationship of landforms with damaged stands. The results showed that： 1） The community was analyzing dominated by Castanopsis species, which were Daphniphyllum macropodum , DaphniphyUum oldhamii , Castanopsis eyrei , Castanopsis fordii , C . carlesii , Cyclobalanopsis hui and llex chinenwsis . 2） D . oldhamii was severely damaged and, C . carlesii , D . macropodum , C . eyrei , C . fordii , and C. hui were moderately damaged, while I. chinenwsis was the most lightly damaged. 3） Plants with different dBH classes showed different damaged modes. The plants with 1.0 - 5.0 cm DBH class were mostly in damaged modes of lodging, stem bending and healthy, the plant with 5.1 - 10.0 cm DBH were subjected to trunk breakage and uprooting, and plants with more than 15 cm DBH mosthly suffered from top breakage. The 10.0 - 15.0 cm DBH class showed the least number of damaged plants. 4） The damaged degrees of different dominant species were differentially affected by elevation and slope.
