Study On Eco-industrial Park's Chains Of Water Cycle Based On The Theory Of Circular Economy

Circular economy is the innovation reflecting on the unsustainable traditional development patterns. It is the results of the understanding of the evolution on the relationship between man and nature. The essence of the circular economy is an ecological economy. It is based on the theory of ecological philosophy. Its core is to the efficient and recycling use of resources. Minimization, reuse, and resources are as its principle. The basic features are the low consumption, low emission, high efficiency. It is to guide and coordinate human relationship with nature. Under the guidance of the theory of the circular economy, the industrial park's development has entered a new stage. And Eco-industrial park construction and development are emerged. Eco-Industrial Park is to focus on the production chain and ecological network construction within the park under the guide of circular economy theory and eco-Industrial theory. And it is to maximize the utilization rate of resources, to reduce emissions to the minimum from the industrial sources, to achieve regional cleaner production.This paper mainly studies the Construction principle and mode of operation of the ecological industrial chain-- the most basic element of the circular economic eco-industrial park, through the using of the combination of theory and case studies, analysis and synthesis, Model Construction methods, on the circular economy and Eco-Industrial Park theoretical research foundations. And under the Beijing Economic and Technological Development Area as an example, this paper researches and constructs the water cycle ecological industrial chain structure of the Beijing Economic and Technological Development Area.Through research, I think that under the guide of the circular economy theory, through the in-depth analysis of the symbiotic relationship between enterprises of the eco-industrial park by the examples, the building of symbiotic ecological industrial chain, conducive to the efficient use of resources and recycling. And it is beneficial to the overall park construction and planning. Thus the sustainable development for the eco-industrial parks is achieved.I hope that the results of this study can provide valuable reference for our economic development cycle.
