油气资源型城市生态工业园产业耦合共生网络生态效率评价

Eco-efficiency Evaluation of Industrial Coupling Symbiosis Network in Oil-gas Resource-based Urban Eco-industrial Park

生态工业园复杂系统中各生态企业间构成产业生态链网,链网中的企业相互促进、互惠互利,构成了产业耦合共生网络系统。为分析生态工业园产业耦合共生网络的发展水平,应用灰关联模型对油气资源型城市生态工业园产业耦合共生网络生态效率进行评价,结果表明,通过经济、环境、物质减量循环和网络结构关联度分析能反映产业耦合共生网络生态效率的总体水平及网络稳定性状态,进一步验证该评价指标体系和评价模型的可行性和可操作性。

In the complex system of eco-industrial park, the enterprises in the complex system of eco-industrial park form the industrial ecological chain network, the enterprises in the chain network promote each other and are mutually beneficial, which constitute the industrial coupling symbiosis network system. In order to analyze the development level of industrial coupling symbiosis network in eco-industrial park, this paper evaluates the ecological efficiency of industrial coupling symbiotic network in oil and gas resource-based urban eco-industrial park by using grey correlation model.The results show that, through economy and environment, the correlation degree analysis of material reduction cycle and network structure can reflect the overall level of eco-efficiency and network stability of industrial coupling symbiosis network, and further verify the feasibility and operability of the evaluation index system and evaluation model.
