| 摘 要： | 毛竹(Phyllostachys edulis)是我国资源最丰富、利用范围最广、经济价值最大的优良竹种(江泽慧,2002),广泛分布于浙江、安徽、江西、湖南和福建等省区.由于该竹秆形高大、枝叶繁茂,一直以来是风雪灾害影响较大的林种之一(肖本权,2003).2008年1月份,我国南方遭受历史罕见的雨雪冰冻灾害,波及范围正好为毛竹的主分布区,毛竹林受灾极其严重.据报道,全国受灾竹林400万hm<'2>以上,其中80%为毛竹林(李潇晓,2008).

| Abstract: | Compared with the undamaged Phyllostachys edulis,the wood mechanical properties of bended bamboo for 4-year-old by frost and snow were studied. It was shown that the wood mechanical properties of bended Phyllostachys edulis were equivalent to or a little less than those of the undamaged bamboo. The bending strength(MOR) of moderately bended bamboo and the modulus of elasticity in static bending(MOE) of heavily bended bamboo were 125.8 MPa and 10 978.9 MPa respectively in the culm base,and compared with thos... |
