| 摘 要： | 根据类比生态系统物质循环,并利用分室模型理论建立了经济-环境系统物质流模型,重点分析了我国经济系统的生产、消费和废弃物还原物质需求在未来30年的存量发展趋势,数值结果表明我国的经济结构调整虽然取得了相对物质减量化,但废弃物还原方面投入不足,生产物质、消费物质和废弃物排放量仍呈指数型增长,经济发展的资源和环境压力依然很大。

| Abstract: | A material flow model,simulated eco-material cycle,for the economy-environment system is set up based on the compartment model theory.The thirty-year changing trends of material stock in the field of production,consumption and waste recycling are discussed.The numerical results indicate that: though some relative material reduction was obtained after executing the policy of industrial restructuring,waste recycling departments were short of enough material input;the stocks of production,consumption and waste... |
