The article starts from the following four aspects and analyzes the resource and environment problems that should be noticed in the construction of the Xiong’an New District and the scientific problems to be faced in realizing the concept of “ecological priority and green development”: (1) How the climate will change; (2) changes in water resources in the Haihe River Basin under the impact of climate change; (3) water resources in the Haihe River Basin and human water use; (4) environmental problems in the construction and development of the Xiong’an New District .
