浙江省竹类资源丰富,竹产业发达,是全国重点产竹省。2008年初特大雨雪冰冻灾害致使该省竹林遭受重创,受灾面积52万hm~2,占竹林总面积的66.4%;直接经济损失36亿元,占林业总损失的37.7%。在介绍南方雨雪冰冻灾害成因的基础上,首先评估了竹林受灾、民生问题、生态功能、次生灾害等4方面的灾害影响;其次,从海拔、混交林和纯林、年龄结构、毛竹钩梢、林地垦抚和使用除草剂、坡度和生长位置等方面分析了竹林受灾原因;最后提出了6项灾害预防对策。
Bamboo resources in Zhejiang Province is rich in bamboo industry developed, is the focus of bamboo production province.
