The water resources supporting capacity for the new-type urbanization of Gansu Province, China

The entropy evaluation method was used to measure the urbanization system and water resources system respectively. The supporting capacity between urbanization and water resources was measured by using the compound coordination model. The research result showed that the supporting capacity of the water resources system to the new-type urbanization development of Gansu Province was continuously increasing from 2000 to 2013. But the overall supporting capacity of water resource system to new-type urbanization of Gansu Province showed a fluctuating declining trend from 2014 to 2017, indicating that the contradiction between new-type urbanization and water resources began to appear with the acceleration of urbanization construction. The supporting capacity of water resources in all regions of Gansu Province was at a low level and the supporting capacity of most regions was undesirable. The relationship between the supporting capacity of water resources in Gansu Province and time series showed a inverted U-shape curve. The supporting capacity of the future water resources will continuously decrease, indicating that the contradiction between new-type urbanization and water resources will be further upgraded.
