摘要

Water and land resources are fundamental to human survival and development. Addressing the challenge of maximizing the comprehensive utilization of these resources, this study is grounded in the “natural-social” binary water cycle theory. Using Luoyang City in Henan Province as a case study, the paper examines the dynamic feedback and quantitative relationships between water and land resources through vector autoregression and panel data models. The results indicate that the expansion of arable land and residential construction areas exerts significant long-term negative pressure on available water resources, while short-term changes in arable land can trigger substantial fluctuations in water availability. Forests and grasslands have a relatively modest impact on water resources, whereas precipitation is the key positive factor influencing long-term water availability, although its short-term direct effect is limited. The effect coefficient of agricultural water consumption on cultivated land area is approximately 0.141, suggesting a relatively weak influence. Similarly, the effect coefficient of ecological water consumption on artificial ecological areas is approximately -0.038, indicating that water-saving initiatives in artificial ecological land have produced initial positive results.
