| 1. Summarization of Eco-city and Eco-city Management SystemIndustry civilization is like a double blade sword, good fortune interweaves with misfortune, profit with harm, while bringing up city civilization, environment problems aroused has menaced the living and development of biology, including human beings. During suffering procedure, the pursuance and exploring of mankind to city development direction and mode has never been interrupted, the view of "taking human being as principle and circumstance as center" for city development has been come into being now, "eco-city" is historic choice for the development of China city. Eco-city is a complex system of "Society-Economic-Natural" with harmonious society, high efficient economy, good ecology circle. Comparing with traditional city, eco-city characters as harmony, high efficiency, durative, systematic, diversity, circumscription, and globality. In which, harmony is the core character and content of eco-city. Not only economy, society, circumstance need develop harmoniously, human being and nature, human being and society, and all groups in society needs to develop harmoniously. According to dissipative structure theory, any are all dissipative structure, so for eco-city, only opening completely to outside, obtaining negative entropy such as material, energy, information, etc, the continuous development of eco-city can be guaranteed. Eco-city management system is composed of subsystem of eco-city management target, management principal, management object, management way, etc. it is a complex big system broadly related, with many targets, multiple layers, multiple variables. The eco-city management system is, at the same time, a dissipative structure, with keeping high degree openness as premises for its development, forming homeostasis as safeguard for good working, non linearity effect as inner impetus of its development.2. Target System of Eco-city ManagementIn order to weigh harmony realization degree of human being and nature, the aim of eco-city, according to scientific, systematic, representative, dynamic and maneuverable principle, choose some of index, set up measurable parameter aggregate-index system to make ration colligation estimation to eco-city.Eco-city evaluation index system is composed of four orderly hierarchies, the highest hierarchy is the target level, which is development target of eco-city, that is the harmonious living environment where human being and nature get along well with each other; second level is guideline level, composed of three sub targets of structure, function and coordination degree of ecology system; the third level is field layer, including 10 generalized indexes. The fourth level is index layer, which is the embodiment of field layer, composed of some single evaluation genes, whose standard value shall make certain according to national standard, advanced city actuality value, or by way of consultant specialist, etc.Guideline layer target ratio is confirmed by Delphi technique. Every gene ratio in target layer and field layer is confirmed by analytical hierarchy process,setting up judge matrix by the way of Delphi technique, seeking eigenvector W and largest latent root λmax, and making consistency test using CI/RI, if the judge matrix has satisfying coherence, then the sub vector wi can be confirmed as authority ratio coefficient of corresponding index in this system. After getting single gene estimate index by comparing with standard value, make ration summing according to each authority ration to figure out system estimate index, then going up rankly, at last figure out eco-city estimate colligation index (ECI), then eco-degree of city can be confirmed. 3. Main Body of Eco-City Management Principal management system of eco-city shall be dissipative structure as well, the three principle conditions - openness, non balance, non line function, are necessarily the characteristics of eco-city principle system. So, changing thoroughly the complexion of using government as the only princip...
