摘要: 随着京津冀城市群的快速发展,永定河流域的生态环境和生态功能受到严重影响。目前存在环境承载力差、污染严重、河道断流干枯和生态功能退化等突出问题,严重制约京津冀城市群自然-经济-社会复合系统的健康可持续发展。已有的研究多从河流单一角度入手探讨永定河流域的修复方案,难以制定可持续的综合治理生态修复模式。本文总结永定河流域的生态水文、流域植被、河道生态护岸、生态质量、生态服务功能与价值评估、生态修复等研究进展,并分析永定河流域在河道、水资源、植被和土壤等方面存在的生态问题,提出永定河流域生态修复模式的建议,为永定河流域生态环境治理提供科学参考。

Abstract: In recent years, with fast urban agglomerations and expansion of the Beijing-Tianjin-Hebei (BTH) region, the Yongding River ecosystem was affected intensively and its ecological function was seriously damaged. At the present, the ecological problems become acute, such as the poor environmental carrying capacity, heavy pollution, dried-up river, and degradation of ecological function. All these prevent the natural-economical-social system in BTH development. However, most of the eco-restoration studies considered only the river itself, while few studies considered the multi-factors to make the sustainable restoration countermeasures. In this article, we summarize the progress in the related topics including the hydrological environment, the vegetation, the condition of bank, the ecosystem function and health, the ecological service value, and the eco-restoration in Yongding River basin. Then, the main existing problems related with the river, water surroundings, vegetation, and soil are analyzed. Finally, we propose the modes for the eco-restoration of the Yongding River, and provide valid scientific suggestion to keep good eco-environment of Yongding River basin.

Key words: Yongding River basin, hydrological environment, vegetation, ecological issues, ecological restoration
