A Study On Index System And Circular Economy System Of Ecological Planning

To coordinate the relation between man and the nature and resource exploitation through ecological planning can be traced back to the works and practices of the ecological thinkers and regional planning pioneers at the end of the 19th century,such as George Marsh,Patrick Geodes and John Powell.Ecological planning theory and practice developed very quickly during the period before World War Two but disappeared in the literature for nearly 20years until the environmental movement in the 1960's.Particularly I.L.McHarg's and his colleagues' outstanding work and planning practice made the ecological planning thinking and methods gain widespread application.Recent trends of ecological planning research and practice develop towards applying the modern ecological knowledge and achievements directly and establishing the theory and methodology based on ecology.development ecomomics and other related disciplines. They shift from quality analysis to quantity simulation with powerful compuer and geographic information system,and from the single goal planning to urban and regional planning in order to promote sustainable development.With the development of ecological planning, its index and circulareconomy system become the important content.This paper brought out some principles for designing the index system of ecological planning.The ecological planning index system(EPIS) for appraising regional development of sustainable, includes 39 indexes.which are constructed by society,environment and economy.The analysis of emergy .created by H.T.Odum, was used to agroecosystems of linyi city. Suggestion and designs to reinforce thesustainable development of angriculture in linyi city were put forward.Ecological planning of Yizhou circular economy industrial park is basee on the principles of circular ecomony and industrial ecology. It aims at setting up a sustainable industrial park and developing the material flow chain.
