流域作为兼具生态屏障功能与经济生产双重属性的特殊地域系统，其生态产品总值（GEP）时空分布及转化路径研究，对破解生态功能区域“保护 ‒ 发展”二元困境具有典型的示范意义。本文从物质供给、调节服务和文化服务三方面构建了流域GEP核算体系，梳理流域生态产品价值的实现模式，并揭示其面临的困境：经济发展水平、区位交通与政策制度形成价值实现的三重阻滞；以全球酱香白酒核心产区的赤水河为例，定量评估2015年和2021年赤水河流域GEP，提出探索“农业 ‒ 酿造 ‒ 文旅”融合发展、竹林碳票交易和横向生态补偿创新实践，推动生态资源向高附加值产品转化；从构建流域多尺度GEP核算范式、创新政策与市场双向驱动的价值实现机制、建立“制度 ‒ 市场 ‒ 技术”协同保障体系方面，提出流域GEP核算与价值实现发展建议，以期为流域绿色高质量发展提供借鉴。

As a unique regional system that synergizes critical ecological barrier functions with economic production, the spatiotemporal dynamics of gross ecological product (GEP) in river basins hold paradigmatic significance for resolving the conservation ‒ development dilemma in ecologically functional zones. This study constructs a basin-scale GEP accounting framework encompassing three dimensions: material supply, regulatory services, and cultural services, and synthesizes models for realizing the value of ecological products in river basins. It further reveals three major constraints hindering value realization: economic development levels, geographical accessibility, and institutional policies. Taking the Chishui River basin as an example, this study quantitatively assesses GEP characteristics in 2015 and 2021. It proposes integrated development practices such as “agriculture ‒ brewing ‒ cultural tourism” synergy, bamboo carbon credit trading, and innovative cross-regional ecological compensation to drive the transformation of ecological resources into high-value-added outputs. Finally, the study proposes development pathways including multi-scale GEP accounting paradigms, innovation- and market-driven value realization mechanisms, and institutional ‒ market ‒ technical safeguards, providing actionable insights for green and high-quality development in river basins.
