Research On County-level Eco-Industry Parks Planning And Design From The Perspective Of Circular Economy

With the advance of industrialization and rapid economic growth, environmental issues and resource issues become increasingly severe. Circular economy which observes the "Reduce, Reuse, Recycle" principles, and aims at benefiting the overall optimum of economy, society and ecology, is a sustainable development approach to reconstruct and transform the existing economic and social systems according to ecological principles. Developing circular economy is the rational choice that can break through the bottleneck of resources and environmental constraints, and practice the scientific concept of developmentCounty-level economic system is the basic unit of the foundation of the entire national economy system. The system which embraces the country's more than 70% of the population, more than 90% of the total land areas and more than 50% of GDP, is China's key areas for the development of circular economy, and the County-level Industrial Park is the central locus of county-level economic industrialization. The eco-industry park, as a new form of industrial organization,which is based on the concept of circular economy and industrial ecology principles, is an industrial park that bears the most environmental significance and green ecological concept. Construction of county-level eco-industry parks can not only be beneficial to the enterprise's own development and growth, but also promote comprehensive and efficient utilization of resources in the region and industry, and guide the green industry orientation and sustainable development.This study, guided by the theories of circular economy, industrial ecology, landscape ecology and social ecology, starting from the current status of industry parks' ecological development at home and abroad, constructs the basic framework of industrial parks'ecological design and a simple eco-industry evaluation system. Thereafter, the paper takes the Ningxiang County's Economic and Technological Development Zone as the object of study for empirical analysis, starting from the park's natural economy and social background, by applying the Energy Analysis to quantitatively analysis and measure the energy flow, logistics flow, information flow, currency flow, population flow, and evaluates its function and status in socio-economic system, and on this basis, formulates a general concept on park's ecological design from the perspective of industrial positioning, which confirms the four leading industries including machinery, rag trade, new material and green goods and designs industrial ecological communities and landscape eco-systems and support systems that consist of core enterprises and relevant subsidiary companies, and thus is in reference to form a real-sense eco-industrial park in which the economic effects, ecological effects and social effects develop in coordination.The paper concludes at the end of the text, and summarizes the research conclusion and presented deficiencies of the paper. And based on this, this paper also proposes prospects for future research to further improve the relevant research results.
