基于“三水共治”的四川省长江流域小流域水生态修复工程科技与伦理案例分析

A Case Study on Technology and Ethics in Small Watershed Water Ecological Restoration Projects of the Yangtze River Basin in Sichuan Province Based on “Three Waters Co-Governance”

摘要: 在“三水共治”理念指导下，四川省长江流域小流域水生态修复工程既体现了系统性治理的技术进步，也暴露出工程实践中科技与伦理之间的深层张力。本文以DLX河流水生态修复工程为案例，分析了原修复方案在技术决策、技术路径、效果评估等方面存在的局限，揭示了原修复工程技术封闭性、评估片面性、模型预测简化与路径依赖等问题背后的伦理困境。进一步从伦理视角出发，构建了“后果–规则与程序–主体”的三维分析框架，系统分析了河流水生态修复工程实践中多元价值冲突与伦理约束机制缺失的根源。研究表明，流域水生态修复不仅需要技术创新，更需建立多元主体参与的决策机制、完善全生命周期的伦理评估体系，推动技术与伦理的协同演进。唯有在“生态优先”理念引领下，构建人与自然和谐共生的治理范式，方能实现长江上游小流域的可持续修复与长效保护。

Abstract: Guided by the “Three Waters Co-governance” concept, the water ecological restoration projects of small watersheds in the Yangtze River Basin of Sichuan Province not only reflect the technological progress of systematic governance but also expose the in-depth tensions between technology and ethics in engineering practice. Taking the DLX River water ecological restoration project as a case study, this paper analyzes the limitations of the original restoration plan in technical decision-making, technological pathways and effect evaluation, and reveals the ethical dilemmas behind its technological closure, one-sided assessment, simplified model prediction and path dependence. From an ethical perspective, a three-dimensional analytical framework of “Consequences—Rules and Procedures—Subjects” is constructed to systematically explore the roots of multi-value conflicts and insufficient ethical constraints in such practices. The research indicates that watershed water ecological restoration requires not only technological innovation but also a multi-subject decision-making mechanism, a improved full-life-cycle ethical evaluation system, and synergistic evolution of technology and ethics. Only under the “ecological priority” concept and a governance paradigm of harmonious coexistence between humans and nature can the sustainable restoration and long-term protection of small watersheds in the upper reaches of the Yangtze River be achieved.
