Analysis of Lubei industrial ecosystems
鲁北工业生态系统分析

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.
