【摘要】 目前,河流生态系统退化已成为威胁中国生态安全的一大难题。为探讨具体河流工程技术选择和生态修复理论、技术集成与创新,该研究回顾了河流生态系统修复的国内外研究进展。在明确河流生态系统退化现状和驱动力的基础上,构建河流生态系统修复体系,归纳国内外用于水质修复和退化河岸湿地修复的技术,并结合南京市秦淮河生态修复工程进行分析,指出要采用综合修复的技术。并对河流生态系统修复的未来研究方向进行了展望。更多还原

【Abstract】 At present, the degradation of river ecosystem has become a problem that threatens China’s ecological security. In order to explore the technical options of specific river, restoration techniques’ integration and innovation on river ecosystem,the related domestic and abroad research progress were reviewed and concluded in this research. Based on the clarification of river ecosystem’s degradation status and its driving factors, a technical system was constructed, the restoration techniques applied on water quality and degraded riverbank wetland were summarized. Combining with the ecological restoration project of Qinhuai River in Nanjing, the comprehensive restoration techniques were further proposed to conduct river ecological resto?ration. Additionally, some prospects referring to restoration of river ecosystem were suggested in future study.更多还原
