Abstract

Abstract

In order to assess the risk of groundwater over-exploitation and encroachment of ecological water demand of rivers on water sustainability, this study took the Huanghuaihai Basin as the research area, used the non-stationary Budyko model as well as the water balance formula, and combined the results of ecological water demand accounting and water consumption data from various sectors. The BlWSI index was chosen to evaluate the water sustainability of the Huanghuaihai Basin based on consumptive blue water use (CBWU), nonrenewable groundwater abstraction (NRGW_A), and surface water over-abstraction (SW_OA). The results showed that the BlWSI indicators which characterized the sustainability of blue water resources had significant spatial and temporal variability in the Huanghuaihai Basin. Among the three river basins, the Yellow River Basin has the lowest degree of water sustainability, followed by the Haihe River Basin, and the Huaihe River Basin had the highest degree of sustainability. During the period of 1960—2000, the sustainability of water resources in the Huanghuaihai Basin showed an increasing trend in different degrees. This study was an important theoretical reference for improving sustainable water resources management in the Huanghuaihai Basin.
