【摘要】：资源流代谢失调是造成产业生态环境问题的主要原因之一,对其实施基于共生网络的生态管理是解决问题的一项重要的举措。运用全生命周期的思想构建了产业资源共生网络及其管理框架,并运用全生命周期评价的方法,借助生命周期评价软件GaBi4,分别选取EI99(Eco-Indicator 99)、CML2001 EP评价体系,以武汉市造纸产业为例,通过设计合理的资源流网络关系及中水、废纸和污泥利用共生路径构建虚拟造纸产业共生网络,对比分析了共生设计系统与原有共生系统的各生态环境影响。并运用市场价值法对共生设计系统的经济效益进行了分析。结果表明:共生设计系统总的环境影响、生态系统质量、人体健康、资源损耗值的环境影响分值分别为1166.445、814.509、148.893、203.045,比原有系统分别减少23.91%、19.15%、46.56%、22.26%;其中富营养化、气候变化的影响分别比原有系统降低56.25%、16.62%。同时共生设计系统通过污水、废纸及污泥的回用,在不考虑市场波动的情况下,可获得1018—7252万元的经济效益。可见,通过构建共生网络的生态管理是提高资源利用效率的有效手段之一,在一定条件下可取得明显的环境和经济效益。
[Abstract]:The imbalance of resource flow metabolism is one of the main causes of industrial ecological environment problems. The implementation of ecological management based on symbiotic network is an important measure to solve the problem. The industrial resource symbiotic network and its management framework are constructed by using the idea of whole life cycle, and the whole life cycle evaluation method is used to select EI99 (Eco-Indicator 99) / CML2001 EP evaluation system with the help of the life cycle evaluation software GaBi4,. The paper industry in Wuhan is taken as an example. By designing reasonable network relationship of resource flow and utilizing symbiotic path of reclaimed water, waste paper and sludge to construct symbiotic network of virtual papermaking industry, the effects of symbiotic design system and original symbiotic system on ecological environment were compared and analyzed. The economic benefit of the symbiotic design system is analyzed by the method of market value. The results showed that the total environmental impact, ecosystem quality, human health, and resource loss of the symbiotic design system were 1166.445814.5098.893203.045, respectively, which were 23.91and 19.156.56 and 22.26g, respectively, compared with the original system. The effects of climate change were 56.25 and 16.62 lower than those of the original system respectively. At the same time, the symbiotic design system can get 1018-7252 million yuan economic benefit without considering the market fluctuation through the reuse of sewage, waste paper and sludge. It can be seen that the ecological management of symbiotic network is one of the effective means to improve the efficiency of resource utilization and can obtain obvious environmental and economic benefits under certain conditions.
