摘要: 对江西安福毛竹林2 008年发生大面积雨雪冰冻灾情的调查和分析。结果表明:毛竹受灾程度与海拔高、林分密度和立竹年龄等有显著相关,其受灾规律为海拔350 m和1 000 m的毛竹林受灾程度分别为51.8%和71.7%;壮龄竹和幼龄竹的受灾程度分别为29.7%和53%;林分密度为2 400~3 000株·hm-2的毛竹林受灾程度为32.5%,分别是立竹度为3 000株·hm-2以上和2 400株·hm-2以下的损失率48.3%和90.3%。此外,毛竹林受灾程度还受林分类型、不同坡度、不同坡向等影响,其表现为纯林大于混交林,陡坡大于缓坡,西北坡大于南坡,说明此次毛竹受灾程度是多因素综合作用的结果。

Abstract: Based on the investigation on the damage of Moso bamboo caused by freezing rain and snow in Anfu, Jiangxi Province in 2 008, the relationship between the damage rate and related factors, such as ages of the culm, the stand and the slope etc. were analyzed in this paper. The results showed that Moso bamboo damage had significant correlation to altitude, stand density and its age. Its damage was 51.8% and 71.7% at 350 m and 1 000 m altitude, respectively. The Moso bamboo damage in 3~5 years and 1~2 years bamboo was 29.7% and 53%, respectively. Its damage was 32.5% in 2 400~3 000 trees•hm-2, 48.3% in over 3 000 trees•hm-2 and 90.3% in below 2 400 trees•hm-2, respectively. Meanwhile, Moso bamboo damage was affected by forest types, different slope, different aspect and so on. Its damage in the pure forest and on steep slopes and northwest slope was severer than that in the mixed forest, gentle slopes and southern slope, respectively. It is concluded that the damage in Moso bamboo plantation was an aggregate result of various factors.
