| 摘要 | Climate change-induced spatiotemporal restructuring of precipitation profoundly impacts the ecological processes of cultivated land in Henan Province's core grain production area. This paper systematically reviews the characteristics of ecological responses in cultivated land and the technological achievements in quality enhancement within this region. Studies reveal that the northward shift of precipitation isohyets has intensified the "spring drought and summer waterlogging" pattern, with prominent issues of soil erosion and secondary salinization; the cultivated land quality grade shows an annual average decline of 0.05–0.10 grades. To address these challenges, the research team has developed a comprehensive technological framework encompassing "ecological process identification — zoned remediation — monitoring and early warning — big data support". Demonstration applications demonstrate that this system has led to an average improvement of 0.8 grades in cultivated land quality, an average grain yield increase of 750–1,500 kg/ha, and a water-saving rate of 40% in irrigation. Current limitations include insufficient technological adaptability; future efforts require strengthening the development of adaptive technologies and intelligent upgrades. |
