Life cycle benefit assessment of ecological slope protection technology in river regulation projects
生态护坡技术在河道整治工程中的全生命周期效益评估

摘要

生态护坡技术作为河道整治工程中兼顾防洪安全与生态修复的重要手段，其全生命周期效益评估对科学决策和可持续发展具有重要意义。本文以生态护坡技术为核心，系统分析其在规划、建设、运营及维护各阶段的经济效益、生态效益与社会效益，并通过案例对比传统硬质护坡方式，揭示其长期综合优势。生态护坡在降低维护成本、提升水质净化能力及增强生物多样性等方面表现突出，具备广泛推广价值。

Abstract

As an important means to balance flood control safety and ecological restoration in river regulation projects, the life cycle benefit assessment of ecological slope protection technology is of great significance for scientific decision-making and sustainable development. This paper takes ecological slope protection technology as the core, systematically analyzes its economic benefits, ecological benefits and social benefits in the stages of planning, construction, operation and maintenance, and reveals its long-term comprehensive advantages by comparing with the traditional hard slope protection mode through cases. Ecological slope protection has outstanding performance in reducing maintenance costs, improving water quality purification capacity and enhancing biodiversity, and has broad promotion value.
