摘要：对工业生态系统进行分析可以发现提高和改进工业生态系统效率以及系统结构的潜在机会.以鲁北工业生态系统为例,采用自然生态系统网络分析方法分别从工业生态系统的链网结构、物种绝对刚度、物种对系统的影响强度及系统稳定性等4个方面进行分析.结果表明,在该工业生态系统中,中位种的比例明显偏少;氢气和SO₂的绝对刚度最大;硫酸、合成氨和磷酸是系统的主导节点;合成氨的系统刚度最大.

Abstract：Analyzing the industrial eco-systems could help to find the potentials to improve the efficiency and structure of systems. The Lu-Bei industrial ecosystem is analyzed deeply in four aspects as the structure of chains, the absolute rigidity of main species, the effect of species on chains, the stability of whole industrial ecosystem. The results show that the proportion of intermediate species in the systems is a bit fewer; the absolute rigidity of hydrogen and sulfur dioxide are on the top of list; sulfuric acid, ammonia and phosphoric acid are the dominant species of the systems; and the ammonia takes the lead of the systemic rigidity.
