Abstract:

Xiong'an New Area is a millennium plan and a national event. Water shortage and water pollution have become the main problems which restrict its development. Different from the existing research on Xiong'an strategic development interpretation and resource profile description, this paper combines with scenario analysis and directional distance function models so as to show the water resources utilization efficiency and water saving potential development landscape and path of different scenarios in 2035 for the first time and it is innovatively based on the development of Shenzhen. The research shows that Xiong'an presents a change from low-efficiency zone to high-efficiency zone to high-efficiency zone in the Business as Usual, Starting Process and Construction Completion scenarios from the perspective of utilization efficiency. From the perspective of water saving potential, the reduction of efficiency improvement space and the increase in metatechnology ratios indicate that water saving potential of Xiong'an has been fully explored. Avoiding direct sewage discharge, developing sewage treatment technology actively and optimizing the industrial structure of the Xiong'an New Area are effective ways to promote the utilization efficiency of water resources, which is also an important guarantee for Xiong'an to realize green ecological development.

Key words: water resources utilization efficiency, water saving potential, scenario analysis method, directional distance function, Xiong'an New Area
