Under the double pressure of ecological vulnerability and economic development, natural resources and ecological environment have become the key constraints to the development of the Yellow River Basin (YRB). This paper proposed a theoretical framework for the relationship between water-energy-food (WEF) and poverty. An improved coupling coordination degree model and the geographical detector were used to evaluate the spatio-temporal coupling between WEF and poverty and its influencing factors in YRB. The results suggest that the levels of coupling coordination increase to different degrees in YRB and its provinces from 2000 to 2019, and the coupling types are characterized by pyramidal-shaped distribution. The regions of YRB are divided into four development types: water-driven type, energy-driven type, food-driven type, and economy-driven type. Spatially, a dominant factor zone is formed with a multi-polar core. Furthermore, some practical suggestions are put forward to promote the effective utilization of water resources and high-quality development according to specific regional situations in YRB. This study will promote coupling coordination and high-quality development in YRB, providing a reference for the coordination of the human-land relationship and regional sustainable development.

在生态脆弱性和经济发展的双重压力下，自然资源和生态环境成为制约黄河流域发展的关键因素。本文提出了水-能源-食物（WEF）与贫困之间关系的理论框架。采用改进的耦合协调度模型和地理检测器对长三角地区WEF与贫困的时空耦合及其影响因素进行评价。结果表明，2000-2019年，长三角及其各省区耦合协调程度均有不同程度的提高，耦合类型呈金字塔形分布。长三角区域分为水驱动型、能源驱动型、粮食驱动型和经济驱动型四种发展类型。在空间上，以多极核心形成主导因素区。并针对长三角地区具体情况，提出了促进水资源有效利用和高质量发展的一些切实可行的建议。本研究将促进长三角地区耦合协调和高质量发展，为协调人地关系和区域可持续发展提供参考。
