| description | The water retention service (WRS) in the Yellow River Basin is highly critical for the ecological security in northern China. Since the implementation of Grain for Green project during 2000, the changes of WRS and land cover in the Yellow River Basin have not been fully revealed, which limited the knowledge of how anthropogenic activities affected ecological processes. To address the issue, this study chose the water yield-based parameter correction method, and adopted the Sen’s slope test, Mann-Kendall analysis and Hurst index methods, firstly analyzing the inter-annual WRS changes in the Yellow River Basin from 1990 to 2020. Specifically, a new index, Ecosystem Service Deficit Index was proposed to accurately distinguish the deficit/surplus state of WRS. The results of land cover change showed that from 1990 to 2020, forest and grassland were both increasing at the rate of +556.5 km2/yr and +508.4 km2/yr, respectively, and cropland was decreasing with a trend of −965.5 km2/yr. Temporally, WRS was weakening (−0.03 mm/yr) during 1990–2000 but was strengthening in 2000–2020 (+0.08 mm/yr). Spatially, the decreases of WRS mainly occurred in the downstream, with the detectable increases in the headwaters of upstream and the midstream; it is noteworthy that the spatial increases of WRS was unsustainable in the future because Hurst index was less than 0.45 in the study area. The ecosystem service deficit index clearly revealed that WRS experienced a long (at least for 3/4 of study period) deficit period until 2011, and was capable of accurately distinguishing WRS surplus/deficit. The new index can also be applied to assess other ecosystem services. Overall, the integrated roles of the local Grain for Green practices and climate change contributed to the recovery of WRS in the Yellow River Basin, but this recovery may not last. More active human interventions needed to be implemented to mitigate future WRS degradation risks. |
