Abstract The lower reaches of the Yellow River have been affected by water shortages since the 1990s. We suggest that water balance and resources in the lower reaches should be considered from the standpoint of water diversion. In this paper, we define a new concept of an “impact zone” to replace that of “basin” for discussion of water resources issues. The objective of this study was to identify the spatial and temporal change in water use in the lower reaches over the last 50 years, and to evaluate the impact zone of the Yellow River.
