Ecological Industrial Park Of Benefit Evaluation Research

Accompanied by rapid economic growth of more than30years, China’sdevelopment is increasingly faced with the bottleneck constraints of the resources andenvironment. The economic development model with substantial input of resourcesand the expense of the environment has been difficult to maintain, it urgently needs tochange the model of economic development. The circular economy produces in thiscontext and with rapid development, it is characterized of “low consumption, lowemissions, high-use”, to change the traditional end of the treatment, environmentalprotection and economic development of organic unify to provide an effective way forbuilding a resource-conserving, environment-friendly society.Eco-Industrial Park based on the theory of circular economy and industrialecology papers, through establishing eco-industrial chain of material and energyrecycling, different enterprises coupling link together to form a sharing of resources,by-product exchange, and waste recycling industrial symbiosis. As an importantcarrier of the practice of circular economy, eco-industrial parks has been a rapiddevelopment, now many countries in the world are vigorously promoting theconstruction of eco-industrial parks. From in June2001when the first nationalecological industrial demonstration parks to December2011it has a total of59national eco-industrial park approved by the state environmental protectiondepartment named or acceptance, provinces and municipalities has also established alarge number of eco-industrial parks.First, the paper summary the basic theory of circular economic andeco-industrial parks from the point of view of connotation and development model, tounderstand internal links between circular economic and eco-industrial parks. Second,it gets some inspiration about building eco-industrial parks through the summary andcomparison of the practice of eco-industrial parks which based on the circulareconomic. Create benefit evaluation index system of eco-industrial parks focus ofeconomic benefits, ecological benefits and park management benefits inSector-integrate eco-industrial parks, Sector-specific Eco-industrial Parks and Venousindustry based eco-industrial parks. And then, taking Zhengzhou economic and Technological Development Zone, Zhengzhou Shangjie district aluminum industrialpark and Changge Dazhou town recycled metal recycling processing Zone as example,to make the benefit evaluation of three different types of eco-industrial parks,information based on research data and evaluation results summed up the problems inthe eco-industrial parks development in Henan Province, and put forward a specificproposal, it provides guidance for the eco-industrial parks health and rapiddevelopment in Henan Province.
