Water Resources Sustainable Utilization

Evaluation of regional water resources sustainable utilization provides a scientific basis for further water resources utilization and social economic sustainable development. How to use a scientific and rational assessment index system to analyze the sustainable utilization of water resources becomes more important. This paper mainly studied on the assessment index system construction for sustainable utilization of urban water resources. A total of 30 indicators were selected to establish for urban water resources sustainable use of the evaluation system.

In order to evaluate regional water resources sustainable utilization, Twenty-six indexes evaluating system is established. On the basis of the fuzzy matter-element analysis and combined with the concept of Euclid approach degree. Through calculating entropy and euclid approach degree between the fuzzy matter-element and the standard (the best) fuzzy matter-element, it can achieves to development and utilization phase of regional water resources and its optimum order in Yinchuan city.

Water footprint theory and method was used to estimate the water footprint of Changsha City in 2009-2012. Based on the estimate of the regional water footprint structure, efficiency indicators of regional water footprint, indicators of water resources sustainable utilization, the water resources utilization status and sustainability was analyzed in Changsha. The results showed that the water footprint and water self-sufficiency rate of Changsha City remained relatively stable in 2009-2012. There not the presence of external dependence of water resources. However, due to the acute annual changes in water resources, Changsha City is still in the imbalance risk of water supply and demand.
