Abstract:
The Xiongan New Area is still in the planning and construction stage, and there are uncertainties about future development scenarios. Predicting the possible water use intensity and water demand under different development scenarios is of great significance for guiding the construction and development of the Xiongan New Area and achieving sustainable use of water resources. The development scenarios of the Xiongan New Area were generalized from three perspectives: the socio-economic development pattern, the water use efficiency pattern, and the eco-environment development pattern. Based on the “Planning Outline for the Xiongan New Area of Hebei Province”, the short- and long-term water use intensity and related socio-economic indicators of the New Area under different development scenarios were predicted by referring to the water use efficiency and socio-economic development indicators in recent years of the domestic new districts and advanced cities at home and abroad. The quota method was used to predict the short- and long-term domestic, industrial and agricultural water demand, and the Tennant method and the quota method were used to predict the short- and long-term eco-environmental water demand inside and outside the river in the New Area. The total water demand for different development scenarios in the year 2022 and 2035 are 0.8~1.0 and 0.9~1.2 billion cubic meters, respectively. While focusing on socio-economic development and eco-environmental protection, strict control of water use intensity can keep the total water consumption to a relatively low level of 0.8~0.9 billion cubic meters. Strictly controlling the water use intensity, and taking various measures to improve water use efficiency are important for the New Area to control the total water consumption and achieve sustainable use of water resources.
