Sustainable waste management in the industrial ecology perspective brings enormous challenges to the existing methodology of waste analysis at the industrial park （IP） scale. In this study, a four-step method was proposed for industrial solid waste （ISW） flow analysis of eco-industrial parks （EIPs） and applied to two IPs in eastern China. According to a park-wide census of 619 industrial enterprises and 105 questionnaires by a survey from 2006 to 2008, the results indicated that： 1） at the enterprise scale, more than 60% of enterprises were small- ISW-generation enterprises which encountered great difficulties on effective waste management; 2） at the IP scale, though the two IPs have set up their own environmental management systems and passed the ISO 14001 certification, the efficiencies of the ISW manage- ment systems have yet to be improved in the industrial ecology perspective; and 3） at the regional scale, more than 97% of ISW flowed within the provincial region, indicating that the provincial governments prevented the wastes from flowing into their own ＂back yard＂. Effective waste management should be placed in a broader perspective. Approaches to sustainable waste management may include wastes exchange, efficient waste and information flow, virtual EIP, waste minimization clubs and regionalization of waste management.

＜正＞To those managers of eco-industrial parks（EIPs）, it is always puzzled that the problem of proper distribute the supply of water resource, many kinds of methods are being searched. In this paper, we take each enterprise of EIPs as a node of Artificial Neural Network（ ANN）, the supply weight of water resource distribution and the transform factors from subject of enterprise to the final target of EIPs as a connect weight of ANN. As a series of iterative learning process, it will be built up that a water resource distribute mode which is most profit to whole EIPs, by an improved ANN algorithm we can get our object in comparative efficient way, at end of the article, an example is computed by designed program and some analysis are given out for the result.
