Analysis of Water Sustainable Utilization in Changsha City Based on Water Footprint Theory

External Dependence ◽

Efficiency Indicators ◽

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.

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.

In order to comprehensively evaluate the water resources carrying capacity in Xiong’an New Area, a system dynamics (SD) model was established to evaluate the regional water resources carrying capacity, for which several scenarios were designed: the original development scenario, the accelerated industrialization scenario, the environmental governance scenario, and the optimization development scenario. The results show that, compared with the original development scenario, the water resources carrying capacity in Xiong’an New Area can be improved in other scenarios, but a water supply and demand gap will be generated due to the lack of groundwater overdraft and a water transfer project. In 2026, under the accelerated industrialization scenario, the population carrying capacity will be 2.652 million, and the water supply and demand gap will be 1.13 × 108 m3; under the environmental governance scenario, the population carrying capacity will be 2.36 million, and the water supply and demand gap will be 0.44 × 108 m3; under the optimal development scenario, the population carrying capacity will be 2.654 million, and since the supply of water resources will be greater than the demand, there will not be a gap between supply and demand, making it the most feasible scenario to effectively alleviate the tension between industry restructuring, environmental management, and water resources development and utilization. The findings of this study can provide reference and decision support for optimizing regional water resources allocation and enhancing water resources carrying capacity in Xiong’an New Area.
