Abstract: Three processing ways of bamboo that turned over by ice and snow were done and the results show that the relation between the DBH and the utilization ratio was conical relationship,so does the relation between the DBH and the economic benefit.In processing way of bamboo mat and recombinant floor,the highest comprehensive utilization(59.4%),sales income(1.06 yuan·kg^-1)and profits(0.24 yuan·kg^-1)was obtained at 9.40 cm,9.15 cm,9.14 cm respectively.In processing way of bamboo mat and construction formwork,The highest comprehensive utilization(56.74%),sales income(0.99 yuan·kg^-1)and profits(0.20 yuan·kg^-1)was obtained at 9.40 cm,9.44 cm,9.27 cm respectively.In processing way of bamboo strips and floor,The highest Comprehensive utilization(58.27%),sales income(1.03 yuan·kg^-1)and profits(0.24 yuan·kg^-1)was obtained at 10.33 cm,10.63 cm、10.39 cm respectively.As for the broken bamboo,the comprehensive utilization,sales income,profits(45.37%,0.82 yuan·kg^-1,0.12 yuan·kg^-1)were lower significantly than normal bamboo(55%,1 yuan·kg^-1,0.2 yuan·kg^-1).The testing results points out that we should attach importance to bamboo waste utilization for raising the utilization ratio and economic benefit.The target of bamboo cultivation is attach more importance to improving output and cultivating medium diameter bamboo.

Key words: moso bamboo, snow disaster, utilization ratio, economic benefit
