永定河是京津冀地区的重要水源涵养区和生态廊道。历史上,永定河经历了由清泉河到浑河、由水灾多发到极度缺水的转变,生态环境发生显著变化。永定河上游、中游地区的农业垦殖、森林砍伐、矿业开采、水利工程建设以及下游地区的海河漕运、筑堤固坝等,是永定河流域生态环境变化的重要驱动因素。反思永定河生态环境变迁及其治理的历史经验和教训,恢复永定河的生机与活力,需要加强上游地区的生态环境保护,发挥中游地区的生态涵养功能,重视下游地区水灾的预防,遵循生态规律,完善永定河治理的制度和机制。

Yongding River is an important water conservation area and ecological corridor in Beijing-Tianjin-Hebei region. In history, Yongding River has undergone a transition from Qingquan River to Hun River, from frequent floods to extreme water shortage, and the ecological environment has undergone significant changes. In the middle and upper reaches of Yongding River, agricultural reclamation, deforestation, mining, and water conservancy project construction, as well as water transport and dike construction in the lower reaches of Yongding River are important driving factors of ecological environment changes in Yongding River Basin. Reflecting on the historical experience and lessons of ecological environment changes, and restoring the vitality of Yongding River, it is necessary to strengthen the protection of ecological environment in the upper reaches, give full play to the ecological conservation function of the middle reaches, pay attention to the prevention of flood in the lower reaches, follow the ecological law, and improve the system and mechanism of Yongding River management.
