A risk assessment for water shortage is constructed to analyze the carrying capacity of water resources in Sheshui River watershed, China. It is based on the information of present economic development. There are several serious environmental problems which might cripple the development potential in Sheshui River watershed. Risk assessment results are used to analyze the carrying capacity of water...
As industrial chain is important for the sustainability of an eco-industrial system, we formulate a system dynamic model emphasizing on importance of industrial chain. Taking machine manufacturing industry of Xuzhou Economic Development Zone for example, a system dynamic model including 6 flows (population, material, capital, technology, water, energy) is designed. By sensitivity analysis 3 sensitive...

Combining Principal Component Analysis (PCA) with BP Neural Network, the paper has established a model to predict water demand for urban development with a demonstration in Hefei city. The results indicate that the error absolute value of prediction model is less than 0.9 percent with an ideal effect. Viewed from PCA results, the principal factors affecting urban water demand can be summarized up...
