安吉县2007-2018 年森林资源动态和成因分析

Dynamics and Analysis on Forest Resources Change during 2007 and 2018 in Anji County

摘要: 根据2007-2018 年5 次森林资源监测数据，对安吉县林地面积、乔木林龄组结构、活立木蓄积量变化情况进行分析。结果表明，在2007-2018 年，安吉县林地面积有小幅降低，乔木林龄组结构趋向合理，近熟林、成熟林占比增加，活立木蓄积量持续增加，森林覆盖率稳定在70%左右。结合安吉县实际情况，指出“十四五”期间，应优化林地结构，改善竹林经营情况；结合“十四五”期间安吉县林地征占用、林木采伐相关政策，预测未来五年林地面积将进一步增加，活立木蓄积量将持续增长，建议“十四五”期间以采伐过熟林为主。

Abstract: Based on forest resources monitoring data during 2007 and 2018, analysis was made on dynamic changes of forestland area, arbor age structure, and living wood growing stock, etc. The result showed that during 12 years, forestland area slightly decreased, the age structure of arbor was reasonable, standing forest stock increased and forest coverage rate was about 70%. Prepositions were put forwarded such as optimization of forest land structure, improving management of bamboo stands, and harvesting over mature forest in the future.
