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。
根據森林資源連續清查成果,從資源數量、結構、質量、分佈等方麵對浙江森林資源動態變化及原因進行瞭分析。結果錶明,浙江省森林資源總量(林地麵積、活立木總蓄積、森林麵積、森林蓄積和竹林資源)呈持續增長態勢;林地利用率、森林覆蓋率均已達高位;中幼林始終是浙江省森林資源的主體,林種結構中公益林麵積蓄積持續增加,樹種結構中闊葉林麵積蓄積持續快速增長。

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 Zhe-jiang 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 for-est 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 continu-ally increasing.In terms of forest structure , broadleaf forest was also increasing rapidly .
