森林资源—环境—经济复合大系统可持续发展优化模型及其应用

An Optimizing Model and Application for Sustainable Development of Large-Scale Forest Resources-Environment-Economy Composite System

运用系统工程方法和大系统理论,分析区域性森林资源—环境—经济复合大系统(FREES)的结构与原理。在可持续发展的总体要求下,将森林资源、森林环境和林业经济三个子系统作为一个有机整体,构建基于ε-约束法的多目标优化模型,以及包含各子系统的目标函数模型、约束条件模型和关联模型在内的FREES大系统分解-协调优化模型。然后,将该模型用于江苏省FREES可持续发展优化问题,得出了具有实际指导意义的最优方案。

According to system engineering methodology and large-scale system theory, this paper analyzes the structure and mechanism of regional forest resources-environment-economy composite system （FREES）. For sustainable development purpose, regarding the three subsystems of resources, environment and economy of forest, as an organic entirety, a multl-objective optimizing model based on ε - constraint method is built. From this, a decomposition-coordination optimizing model for large-scale FREES is established, containing objective function, constraint condition and relevant models of the subsystems. Then the model is used to optimize the Jiangsu FREES for its sustainable development, obtaining an optimal solution having practical directive function.
