摘　　要：根据森林资源连续清查成果,从资源数量、结构、质量、分布等方面对浙江森林资源动态变化及原因进行了分析。结果表明,浙江省森林资源总量(林地面积、活立木总蓄积、森林面积、森林蓄积和竹林资源)呈持续增长态势;林地利用率、森林覆盖率均已达高位;中幼林始终是浙江省森林资源的主体,林种结构中公益林面积蓄积持续增加,树种结构中阔叶林面积蓄积持续快速增长。According to the results of the continuous forest inventory,the dynamic of Zhejiang forest resource and its causes were analyzed and studied from the aspects of the quantity,structure,quality and distribution of Zhejiang forest resources. The results showed that,the total amount of Zhejiang forest resources（ forestland area,total growing stock,forest area,forest accumulation and bamboo resources） have showed a sustained growth. The forest utilization and forest coverage rate have reached a high average. Young and middle-aged forest have s been the main part of Zhejiang forest resources,while the area and accumulation of public welfare forest have been continually increasing. In terms of forest structure,broadleaf forest was also increasing rapidly.
