摘要:
能源代谢对区域经济社会发展具有重要作用和影响力。本文采用生态网络分析方法对山东省能源代谢进行了分析。我们首先构造了2000、2005、2010和2014年山东省整体能源代谢网络，然后对其进行了流量分析和效用分析，探讨了能源代谢网络的系统结构及功能关系。结果表明：山东省能源代谢系统是一个由竞争关系以及控制关系所主导的系统，各节点之间的共生关系较少；随着时间推移，各组分间的作用途径也更为多样，代谢路径数量和连通性不断提高，是一个具有高度竞争和掠夺性的代谢共生体。
Energy metabolism plays a great role in regional socio-economic development. This paper ana-lyzed the energy metabolism of Shandong Province by ecological network analysis. The overall energy metabolism network of 2000, 2005, 2010 and 2014 of Shandong Province was firstly constructed. Then flow analysis and utility analysis indicators were conducted to investigate its structure and functions. Results show that the energy metabolism network of Shandong Province is dominated rather by competition and control relationships than by symbiotic relationship. The pathways between different components are more diverse, and the number of metabolic pathways and connectivity constantly improve over time, while the network becomes a highly competitive and predatory metabolic symbiont.
