Analyzing Cleaner Production,Industrial Ecology and Circular Economy Upon Ecological Paradigm.

With the aid of ecological theories,analogical analysis of cleaner production,industrial ecology and circular economy was done on four ecological scales,individual,population,community and ecosystem.Internal relationships were discussed between cleaner production and individual ecology,between ecological industry and population ecology community ecology,as well as between circular economy and ecosystem ecology,clarifying that the three patterns were compatible and that progressive relationships existed between them.From the view of ecological theory,they were three analogs,that is,cleaner production had an analogy to individual ecology,industrial ecology did to population ecology,and above said analogy also existed between circular economy and ecosystem ecology.Based on the findings,limitations existing in the research and practice of cleaner production and industrial ecology were analyzed.It is thus concluded that in future cleaner production should be implemented at a higher level and in a larger scope,that the study of industrial ecology should be conducted at the industrial ecosystem level.From the angle of sustainable development,the practices of cleaner production,industrial ecology and circular economy at different levels and scopes will eventually propel man steadily towards his ultimate ideal goal of sustainable development.
