| 英文摘要 | CONTEXT: Saline-alkali soils, serving as the reserve resources of arable land for food security, require remediation to relieve salinization indicators and improve agricultural potential yield. Although previous studies have quantified potential yield gains on saline-alkali soils at the field scale, the overall potential production and the spatial heterogeneity of yield improvement across these soils remain uncharacterized. OBJECTIVE: The objective is to quantify the increasement in wheat production potential and spatial distribution differences across saline-alkali soils in China's Huang-Huai-Hai region under remediation measures. METHODS: Here, we present a framework that integrates the Global Agro-Ecological Zones (GAEZ) model with remediation-adjusted soil salinization indicators derived from a field-scale meta-analysis. We applied this framework to simulate wheat potential yield improvement of saline-alkali soils in a typical region with saline-alkali soils-the Huang-Huai-Hai Region (HHHR), China from 2011 to 2020, considering both perspectives of remediation measures (chemical, biological, and integrated measures) and administrative units (Shandong, Hebei+Beijing, Tianjin, Henan+Anhui, and Jiangsu). RESULTS AND CONCLUSIONS: Our results demonstrated strong consistency in potential yield improvement compared to observed field data (R2 = 0.7, RMSE = 630 kg/ha). The soil electrical conductivity, exchangeable sodium percentage, and pH of saline-alkali soils under remediation decreased by 10.31%, 22.92% and 1.2%, respectively, in the entire region. The maximum improvement of wheat potential production under remediation in saline-alkali soils of HHHR could reach 1.26 million tons (1.03-1.79 million tons), could meet the annual wheat demand for 15.85 to 27.54 million people. Among the approaches assessed for enhancing the potential yield of saline-alkali soils, integrated measures demonstrated the better effective results. From the perspective of administrative units, the potential yield of improved saline-alkali soils in Henan and Anhui increased to 1.22 times the pre-remediation. SIGNIFICANCE: We provide a new framework for spatially explicit assessment of wheat potential yield improvement in saline-alkali soils, providing a scientific basis for the sustainable development and utilization of saline-alkali soils. |
