基于碳封存模型和CEEH模型的森林管理策略研究

Research on Forest Management Strategies Based on Carbon Sequestration Model and CEEH Model

二氧化碳作为温室气体之一,对地球的生态环境有较大影响。森林的生态功能是自然界吸收二氧化碳的重要环节,然而考虑到人类的社会发展需求,提高森林碳固量同时要兼顾其经济功能。为了探究森林的固碳能力,制定合理的管理策略,文章首先结合国际林业指标,根据实际情境划分森林,综合考虑了气候、树龄和树种等因素,通过运筹学方法构造了碳封存的线性规划模型;选取影响森林价值平衡的4个一级指标和9个二级指标,建立了一个名为CEEH的森林价值决策模型,运用层次分析法量化并确定了森林经营相关的指标权重,计算出CEEH得分并确定过渡点;最后针对四类森林问题提出具体的可持续管理计划。

Carbon dioxide,as one of the greenhouse gases,has a significant impact on the planet's ecological environment.The ecological function of forests is an important link in the natural absorption of carbon dioxide.However,given the needs of human social development,it is important to take into account the economic functions of forests while increasing their carbon sequestration capacity.In order to investigate the carbon sequestration capacity of forests and to formulate reasonable management strategies,this paper firstly combines international forestry indicators,divides forests according to actual situations,takes into account factors such as climate,age and tree species,and constructs a linear programming model for carbon sequestration by means of an operational research method.Then four primary indicators and nine secondary indicators were selected to influence the balance of forest values,and a forest value decision model called CEEH was established.Hierarchical analysis was applied to quantify and determine the weights of relevant indicators related to forest management,calculate the CEEH score and determine the transition points.Finally,specific sustainable management plans are proposed for the four categories of forest issues.
