Abstract: 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.
