仪征市胥浦河环境经济价值实现的研究

Research on the Realization of Environmental-Economic Value of Xupu River in Yizheng City

摘要: 生态产品价值核算通过科学量化自然生态系统的服务功能，为破解“资源无价、生态无偿”困境、构建生态补偿机制、推动绿色低碳发展提供关键决策依据。本研究基于生态系统生产总值(GEP)核算框架，综合评估仪征市胥浦河的环境经济价值及其实现路径。通过物质产品价值(EMP)、调节服务价值(ERP)和文化服务价值(ECP)三维度量化分析，得出胥浦河流域GEP总量为2.48亿元，其中水资源供给(1.83亿元)、洪水调蓄(1466万元)、水质净化(473万元)、固碳(106万元)及物种保育(427.5万元)构成主要调节服务价值，生态旅游(4000万元)主导文化服务价值。本研究为长江下游中小河流的生态产品价值转化提供科学依据，助力“绿水青山”向“金山银山”的实践转化。

Abstract: Ecosystem product value accounting provides critical decision-making support for addressing the “unpriced resources, uncompensated ecology” dilemma, establishing ecological compensation mechanisms, and promoting green low-carbon development by scientifically quantifying the service functions of natural ecosystems. This study evaluates the environmental-economic value and realization pathways of the Xupu River in Yizheng City based on the Gross Ecosystem Product (GEP) accounting framework. Through a three-dimensional quantitative analysis—encompassing material product value (EMP), regulating service value (ERP), and cultural service value (ECP)—the total GEP of the Xupu River Basin is calculated at 248 million yuan. Key components include water supply (183 million yuan), flood regulation (14.66 million yuan), water purification (4.73 million yuan), carbon sequestration (1.06 million yuan), and biodiversity conservation (4.275 million yuan) as primary regulating services, while ecotourism (40 million yuan) dominates cultural services. The study offers a scientific foundation for transforming ecological products into economic value in small-to-medium rivers of the Yangtze River Delta, facilitating the practical transition from “green mountains and clear waters” to “golden mountains and silver mountains.”
