摘要
本文从产业结构和环境污染两大系统以及影响这两大系统的各个子系统出发,构建反映产业结构对环境污染影响的系统动力学模型。在对模型进行有效性检验后,预测中国环境污染的发展变化趋势。在此基础上,通过系统参数变量的适当调控,分析调整产业结构、科技投入强度和能源消费强度等不同调控方案对未来环境污染变化的影响。研究结果表明:1按照现有系统发展规律,至2022年,工业废气排放量、废水排放量和固体废物产生量分别预计达到1176190亿标立方米、146.98亿吨和115.57亿吨。2适当调整产业结构、增加科技投入强度和降低能源消费强度能够使得环境污染物排放显著下降。
The system dynamics model on the effect of industrial structure to environmental pollution is built based on the systems of environmental pollution, industrial structure and their influencing subsystems. The future development trend of environmental pollution in China can be predicted after the effectiveness test of model. Furthermore, through the proper regulations of system parameters, the future changes of environmental pollution can be simulated and predicted in different control schemes such as adjusting industrial structure, scientific and technological intensity and energy intensity. The results indicate that industrial waste gas emissions, industrial waste water emissions and industrial solid waste outputs in China would be expected to reach 117 619 billion standard cubic meters, 14. 698 billion tons and 11. 557 billion tons respectively by 2022, according to the existing law of development. In addition, adjusting industrial structure, increasing scientific and technological intensity and reducing energy intensity will lead to the obvious decrease of environmental pollution emissions.
