立足于生态经济理论,利用SD模型方法和柯布-道格拉斯生产函数,构建宁夏“资源-环境-经济系统”结构模型,表明经济增长、资源枯竭和环境影响之间的反馈关系。包括8个子系统:生产子系统,人口子系统,人力资本子系统,人造资本子系统,不可更新资源子系统,可更新自然资源子系统,技术子系统,环境污染子系统。采用系统动力学专用模拟分析软件VENSIM PLE5.4模拟宁夏“资源-环境-经济系统”可能的运行情景,对宁夏“资源-环境-经济系统”运行规律进行探索,旨在揭示宁夏不同发展模式下的环境响应,为宁夏的可持续发展决策提供参考。
Based on the theory of ecological economy, the SD model method and the Cobb-Douglas production function are used to construct the Ningxia “resource-environment-economic system” structural model, which shows the feedback relationship between economic growth, resource depletion and environmental impact. Including eight subsystems: production subsystem, population subsystem, human capital subsystem, artificial capital subsystem, non-renewable resource subsystem, renewable natural resource subsystem, technology subsystem, environmental pollution subsystem. This paper uses the simulation software VENSIM PLE5.4 of system dynamics to simulate the possible operating scenarios of Ningxia “resource-environment-economy system” and explores the operating rules of “resource-environment-economy system” in Ningxia to reveal Ningxia The environmental response under different development modes provides references for the sustainable development of Ningxia.
