摘  要:
基于系统动力学理论,根据吉林森工集团森林资源状况和森林生态系统服务评价结果,设计了三套方案并利用仿真模拟预测法,应用Vensim软件对吉林森工集团在2008—2020年的森林生态系统服务进行仿真预测研究,目的是预测未来何种方案产生的森林生态系统服务价值最大。结果显示:(1)2020年,方案三在维持天保工程年均造林面积和采取禁伐措施下,森林生态系统各项服务提供的实物量和价值量均最大。(2)不同方案下的吉林森工集团森林生态系统服务价值均随时间的推移呈递增态势。(3)方案三的森林生态系统服务价值以2015年为拐点增长最为明显,由2008年的385.08亿元(人民币,下同)增长到2020年的19 394.08亿元,故应选择能提供最大森林生态系统服务价值的方案三。仿真预测研究对吉林森工集团的林业发展和战略制定都有着十分重要的意义。

摘  要:
Based on the theory of system dynamics, according to the forest resources status and forest ecosystem service evaluation results of Jilin Forest Industry Group,three schemes were designed to predict forest ecosystem services in 2008—2020 using simulation model method by Vensim software. The aim of the study was to predict which future scheme could generate the greatest value of forest ecosystem services. The results showed that :(1) In the condition of Plan, under the maintained average planting area in natural forest protection project and the adopted ban measures,forest ecosystem services provided by converting and value were the largest.(2)The services value of forest ecosystem of Forest Industry Group under different schemes was increasing with time.(3) Forest ecosystem service value of Plan was increased from 38. 508 billion Yuan in 2008 to 1.939408 trillion Yuan in 2020,with a turning point growth that most obvious in 2015. Jilin Forest Industry Group should choose Plan 3 which provided the largest value of forest ecosystem service. The simulation prediction research on the forestry development and strategy formulation had very important significance in Jilin Forest Industry Group.
