Industrial Symbiosis Network At Eco-industrial Parks

In order to solve the question of sustainable production, experts are trying to find out a material-recycling method。The recycling method in natural ecological system are always thought high of, and make experts aware of establishing industrial system by imitating it。However, the industrial system is man-made, which has a lot of defects, which impede its functions。How to solve the defects and perfect industrial system, is one of the hot researches by now, which is the meaning and goal of the article.At first, some theories and practices on imitating natural ecological system are introduced, on which some thoughts of the authors' are put forward.。In the second, based on these theories and practices, the author tries to establish an ecological symbiosis network, between which , some important active factors, such as fusion and fission, are analyzed in the establishing of ecological symbiosis network and the importance of keeping the balance of the network, lest the chain break off or break up。In the third, kinds of flows are analyzed, for which the method of optimizing are posed。At last, questions about ecological symbiosis network are summarized, to which some answers are provided...
