International Research Advance of Industrial System Ecologization and Its Reflection

In line with the feature of industry's configurator of resource, as well as controller of pollutants discharge, it is of significant importance to shift from an open loop system of "resource-product-waste" to a closed loop system of "resource-product-waste", especially in coordination between industrial symbiosis and the environment, and in sustainability of industrial system. Based on the impact of industrial activities on natural ecosystem, the idea of industrial ecology has formed gradually since 1980s; therefore, the research of industrial system-based ecology is expanding continuously in international academic society. This paper summarizes the international research advances and orientations in six aspects, including industrial ecology and practical tools, ecological efficiency of industrial system, emergy analysis of industrial system, risk and vulnerability of industrial system, ecological stimulation of industrial system, cleaning and sustainability of industrial system. And author provides twofold of research reflections, which are strategically shifting from "adjustment" to "adaptation" of industrial system in research perspective, shifting from "simplicity" to "in- tegrity" in discipline base.
