| Technical development results in the economic growth, but at the same time it involves human in the natural crisis and unsustainable danger. The humans have put forward the sustainable development strategy. Meanwhile, with the enlightenment of ecology, humans have explored a new approach for technical development. Focused on the research of how to imitate the ecosystem, the industrial ecology provides both technical and theoretic support for the formation of ecologic industrial park. The proposition of the sustainable development and industrial ecology forms the background and technological foundation of the ecologic industrial park.Ecological industrial park itself is established on those industrial parks which greatly rely on technology. It organizes production in accordance with the principle of the industrial ecology, which is the most distinguished characteristic from other industrial parks. From the perspective of technical characteristic, economical industrial park is given a definition as follows. Taking the industrial ecology as the rationale, and the technical chain as the support, industries and enterprises carry out production according to the new technical path of industrial metabolism theory. In order to complete the technical innovation and conformation process, the entire park area ensures the technical fusion among the technical chain, maintains the material stream smoothly, and forms the sustainable ecosystem.Then, this thesis analyses the general character differentiating the existing ecological industrial park from the ordinary ones---technical chain, the foundation of the ecological industrial park. Due to imitate the food chain in the ecosystem, the technical chain is created. As a result, the ecological industrial park should construct special infrastructure distinguished from the one in ordinary industrial parks. The characteristic brought about in the ecological industrial park by the special infrastructure is called the technical characteristic.At last, this thesis proposes that the technical characteristic in the ecological industrial park derives from the characteristic of the technical chain, which is attributed to the similarity of the development direction between the industrial system and the ecosystem. According to the mature degree of the food chain, the realistic form of ecosystem can be divided into level one, two, and three; similarly, according to the mature degree of the technical chain, the realistic form of the industrial system can be... |
