摘　　要：在四川省毛竹资源集中产地宜宾市,调查2008年初冰雪冻雨天气对毛竹造成的危害,分析毛竹受害程度和分级状况。结果表明:毛竹林平均受损率为14.6%,受损率10%～30%的中度受损面积占66.7%,毛竹林受损以倒伏破裂为主,占受损总株数的78.3%。毛竹受害原因主要是冰雪冻雨重力作用,立地海拔较高、坡度较大、土壤瘠薄,以及经营粗放的毛竹林损失严重。重建措施包括适地适树、严格执行营造林技术标准和规程、选用新品种和及时监测预防等。The bamboo forest of Phyllostachys edulis at the central production region in Yibin City of Sichuan Province was heavily damaged by the ice-snow-frozen rain weather in the early spring of 2008.The damage intensity and categorization were investigated and analyzed.It was found that the average damage ratio was 14.6% of total plants.The moderately damaged stand with 10%～30% plants damaged took a percentage of 66.7 of the whole forest area and the major damage types exhibited as plant fallen and culm split,consisting of 78.3% of the damaged bamboos.The bamboo forest damage was mainly attributed to the accumulative weight of ice or snow on the surface of plant body.On the site of higher altitude,steeper slope and poorer soil or in the stand with poor management,the severer damage was found.The integrated measures were recommended for reestablishment of the damaged bamboo forest,including more effective site selection,more strict exercise of silvicultural standard or criteria,more successful application of improved bamboo varieties or species,and more efficient monitor and protection before the harsh weather coming.
