建国以来,特别是1963年大水以后,河北省主要河道和一部分支流河道都经过了扩大治理,防洪能力普遍有所提高,但大多数河道只能抗御一般洪水,如大清河、潮白河、北运河、蓟运河、永定河防洪标准仅为10至20年一遇。卫河、卫运河、漳卫新河、滏阳新河、滹沱河、子牙新河防洪标准虽然提高到50年一遇,但还存在不少问题,近期内很难全部解决。鉴于上述情况,如遇大水还必须发挥分、滞洪水区的缓洪、蓄洪作用,才能最大限度的减少
Since the founding of the People’s Republic of China, especially after the flood in 1963, the major river courses in Hebei Province and some of the tributary rivers have undergone extensive control and the flood control capabilities have generally been raised. However, most of the river courses can only resist ordinary floods such as the Daqing River, Chaobai River and North Canal, Jiyun, Yongding flood control standards for only once every 10 to 20 years. Although Wei River, Wei Canal, Zhangwei New River, Xingyang New River, Hutuo River and Ziya New River flood control standards have been raised to 50 years, many problems still exist and it is very difficult to solve them all in the near future. In view of the above, in case of floods must also play points, delaying flood buffering, flood storage, in order to minimize
