Abstract:
In order to evaluate the effects of water source replacement quantitatively, joint allocation model of the external and local water resources was established and applied in the water-receiving areas of Haihe Basin of the 1st stage of South-to-North Water Transfer Project (SNWTP). Based on the analysis of the water source replacement process, different scenarios of water allocation were analyzed under the conditions of groundwater control and eco-environmental restoration in the water-receiving areas. The results showed that one third of intake water from the 1st stage of SNWTP is used to support the increasing urban water demand, and two thirds is used to replace the existing unreasonable water uses and to return to the agricultural and ecological construction. The water source replacement can improve the eco-environment conditions in the water-receiving areas. However, the conflict between water resources shortage and ecological deterioration cannot be solved for the 1st stage of SNWTP, and therefore other measures need to be conducted to optimize the profit of SNWTP, including water saving, pollution control, groundwater overdraft control, and reasonable allocation of various water sources.
