摘要
The stability and reliability of the symbiosis network in industrial parks have attracted many concern of researchers. How to construct the symbiosis network and deal with the accidents happened in a symbiosis network is a key problem. Analogizing the concept of redundancy species and complex network redundancy, a framework to quantify the redundancy on symbiosis network was established to improve the stability and reliability in this paper. In addition, we characterized the redundancy of an industrial symbiosis network into three types: stock redundancy, scale redundancy and functional redundancy and further quantified the impact of redundancy on the stability of symbiosis network and environmental risks. The results show that increasing the stock redundancy can improve the stability of a symbiosis network to a certain degree (except tailing impoundment) while only slightly changing the environmental risks. The stock redundancy, scale redundancy and functional redundancy were 0.54, 0.09 and 0.71, respectively. The tailing impoundment temporarily used for hazardous waste storage is effective measure to improve redundancy of the symbiosis network. The case study of a hazardous waste symbiosis network confirmed that the scale of a temporary storage facility and other downstream symbiosis provided useful insights for developing and managing of Eco-industrial parks. Also it is useful for planning and designing of Eco-industrial parks.
