| 英文摘要 | Understanding how soil salinization affects evapotranspiration (ET) is vital for water managing water and restoring ecosystems in dry regions. This study measured the impact of soil salinization on ET in the Lower Yellow River Irrigation District from 2000 to 2016. We used the PML-V2, a Global Soil Salinity Map, and an innovative soil salinity transition matrix. Using grid-based analysis with multiple linear regression, we identified the main factors controlling ET and assessed how changes in soil salinization altered these controlling factors. Our results show that soil salinization in the region is mostly slight. However, it intensified in the south while alleviating in the north. ET generally decreased from the southwest to the northeast, but overall, all 15 sub-districts showed an increasing trend in ET over the study period. ET increased with higher precipitation, temperature, and NDVI, but decreased with higher soil moisture. Crucially, increasing salinization suppressed ET. It also enhanced the positive effects of precipitation and NDVI on ET, shifting the driving mechanism from 'temperature-soil moisture driven' to 'precipitation-NDVI driven.' Conversely, decreasing salinization strengthened the effect of temperature and amplified the negative impact of soil moisture on ET, reverting to 'temperature-soil moisture driven' mechanism. We also observed declining soil moisture alongside increasing ET, highlighting the need to address soil salinization. These findings clarify how salinization influences ET and support sustainable water management. |
