[目的]对2008年初特大冰冻灾害造成的我国南方常绿阔叶林灾害类型及受损程度进行评估。[方法]2009年5月在大明山常绿阔叶林典型受灾地带设置了80个20m×20m(3.2hm2)调查样地,对其中6个优势种的受灾情况进行了调查。[结果]大明山常绿阔叶林受灾严重,受灾率达51.8%;不同树种的受灾率各不相同,其中以罗浮槭受灾率最高,栓皮木姜子受灾率最低;各树种受灾类型以冠损率最高,掘根率最低,且树种间的受灾率、冠损率和折干率有0.05水平显著差异;各树种的未受灾及灾害类型之间的树高、胸径、冠长均有0.05水平显著的差异。[结论]大明山自然保护区常绿阔叶林冰冻灾害类型的形成与树木的大小有关;云贵山茉莉、罗浮槭、罗浮柿更易发生掘根、冠损等灾害。
[Objective] To evaluate the disaster types and the damage degree of the evergreen broad-leaved forest in southern China caused by the special freezing disaster in early 2008. [Method] Eighty 20 m × 20 m (3.2 hm 2) survey plots were set up in May 2009 in the typical affected area of the evergreen broad-leaved forest in Daming Mountain. The affected conditions of 6 dominant species were investigated. [Result] The evergreen broad-leaved forest in Damingshan had a serious disaster with a disaster rate of 51.8%. The disaster rates of different tree species were different. Among them, the highest disaster rate was in Luo-feng-ai and the lowest was in " The highest damage rate and the lowest rooting rate, and there was a significant difference in the rates of damage, crown damage and dry-down between 0.05 and 0.05. The tree height, diameter at breast height and crown length of all tree species were 0.05 Significant differences in levels. [Conclusion] The formation of the frozen disaster type in evergreen broad-leaved forest in Damingshan Nature Reserve was related to the size of the tree. The damages of mulching, crown loss and other damages occurred more easily in jasmine, jasmine, and maple.
