Changes in China’s Groundwater Storage with Natural and Anthropogenic Drivers
Groundwater is the major source of fresh water, and it performs a crucial role in maintaining ecosystems and adapting humans to climate variation. Due to excessive reliance on groundwater in some regions, the amount of groundwater being consumed is higher than the recharge, which leads to a durative decline of groundwater level. This study analyzed the spatiotemporal variability in groundwater storage (GWS) in China. And the possible drivers of observed GWS changes were also identified. GWS level displayed large regional disparities with higher reserves in the Yangtze River Basin and Songhua River Basin. Temporally, GWS level showed decreasing trends in the North China Plain region, Yellow River Basin, Inner Mongolia Plateau and Junggar Basin. And, GWS showed a significant increase in the Tibetan Plateau and Songhua River Basin. Without considering the impact of human activities, groundwater reserves are also showing a decreasing trend in future climate scenarios in most of the 15 zones. Contribution analysis of driving forces on the basis of the percentages of standardized coefficient (r) suggested that the variations of GWS were largely controlled by anthropogenic activities with the contribution proportions of 35.43%–73.37%. And the contribution proportions of natural drivers accounted for 26.63%–64.62%, with the key factors of precipitation, temperature and vegetation cover. The results would help to formulate sustainable strategies for managing groundwater resource.
