4. Conclusions
- (1)
- The indicator system constructed in this paper included three aspects: water resources condition subsystem, socio-economic subsystem and eco-environment subsystem, with weights of 0.465, 0.291 and 0.244, respectively. The influence on the sustainability of water resources use was in the following order: water resources condition subsystem > socio-economic subsystem > eco-environment subsystem. Among the EISWRU, the water resources per capita accounted for the largest proportion, and water consumption structure, agricultural water use efficiency and forest coverage present a greater influence on the sustainability assessment of water resources use.
- (2)
- The overall degree of sustainability of water resource use in China’s 31 provinces is not high, 42% of the regions have unsustainable water resources use and there is a clear spatial distribution trend, with the southeastern regions and economically developed regions having a higher degree of sustainability of water resource use. In terms of the water resources condition subsystem, the western parts with lower population density, Heilongjiang Province and the southern regions with abundant water resources have better water resources conditions. In terms of the socio-economic subsystem, the southeast coastal regions are rated higher than the western and northern regions, with the economically developed regions of Beijing, Tianjin, Shanghai and Chongqing rated the highest. In terms of the eco-environment subsystem, the ecological environment subsystem in the southern region is at the lowest rating and the northern regions are normally rated higher than the southern regions, except for Zhejiang. The irrational industrial structure of less economically developed regions often results in a poor water consumption structure, leading to unsustainable water resource use. Water resources in economically developed regions are used in a more efficient way, but excessive exploitation could exceed the carrying capacity of the water environment and easily cause environmental pollution and ecological imbalance.
- (3)
- Each of China’s 31 provinces has a different level of sustainability in the use of water resources and faces different challenges. Each region should develop measures to ensure water security according to its local conditions. For example, the six regions of Shanxi, Shandong, Henan, Anhui, Liaoning and Gansu are poorly endowed with water resources and have low water resources per capita, but they are in a low level of water resources development and utilization, so they could achieve their water resources potential and strengthen the use of non-conventional water resources.
