The in-depth study on the rule of temporal and spatial variation of water resources system in Gansu Province is the scientific basis for alleviating the contradiction between human, ecology, and water and will provide scientific basis for optimizing the relationship between social economic development, environmental improvement and water resources, planning reasonable water structure and sustainable development of water resources. Global climate and environmental changes are endangering global water resources; and several approaches have been tested to manage and reduce the pressure on these decreasing resources. Ehrlich and Ehrlich proposed the concept of “ecosystem services” as a way to assess the impact and effectiveness of ecosystems on human society. Ecosystem services are “the conditions and processes through which natural ecosystems, and the species that make them up, sustain and fulfill human life”. On the basis of the unique perspective analysis of the inter-annual and regional changes of water resources in Gansu Province from 2010 to 2016, the Lorenz curve and the Gini coefficient statistical method are used to quantitatively describe the change process and evolution characteristics in temporal and spatial distribution of total water consumption and water consumption structure in Gansu Province. The results show that 1, the spatial distribution of water resources in Gansu Province is quite uneven, the water resources are mainly concentrated in Gannan and Longnan, and the most serious water scarcity area is Hexi area, 2, the overall regional difference of total water consumption in Gansu Province from 2010 to 2016 is higher, and 3, water resource shortages are becoming an increasingly common and serious global problem. The special distribution of water consumption in the three major industries is relatively balanced.
