摘　　要：森林对气候变化和地区经济发展有着至关重要的作用.我国已成为全球森林资源增长最多和人工造林面积最大的国家,但我国的森林资源管理处于起步阶段.本文以江西省人工林为研究对象,利用树木生长收获模型和Faustmann-Hartman模型计算出森林的最大综合效益,得出对应的最佳轮伐周期,并据此制定管理计划.研究结果表明:江西省针叶人工林和阔叶人工林最佳轮伐周期分别为20年和7年,针阔混交人工林最大综合效益对应的针叶比例为95%,最佳轮伐周期为20年.江西省现行管理计划人工林一年的综合效益为4 468 493 789元/年,而本研究制定的管理计划人工林一年的综合效益为5 890 640 943元/年.本研究中的管理计划与江西省现行的计划相比效益更高.Forests play a crucial role in climate change and regional economic development.China has become the country with the largest growth of forest resources and the largest area of plantation forests in the world,but the management of forest resources in China is in its infancy.This paper takes the plantation forests in Jiangxi Province as the research object,uses the tree growth harvesting model and the Faustmann-Hartman model to calculate the maximum comprehensive benefits of the forests,derives the corresponding optimal rotation cycle,and formulates the management plan accordingly.The results of the study showed that the optimal rotation cycles for coniferous plantation forests and broadleaf plantation forests in Jiangxi Province are 20 and 7 years,respectively,and the maximum comprehensive benefit of mixed coniferous and broadleaf plantation forests corresponds to 95%of the proportion of coniferous leaves,and the optimal rotation cycle is 20 years.The comprehensive benefit of one year of plantation forest under the current management plan in Jiangxi Province is 4468493789 yuan per year,while the comprehensive benefit of one year of plantation forest under the management plan developed in this study is 5890640943 yuan per year.It is obvious that the management plan in this study has higher benefits compared with the current plan in Jiangxi Province.
