河北省境内中小河流众多,洪水灾害是制约区域社会经济快速发展和威胁人民生命财产安全的最主要自然灾害之一。通过分析水汽来源、天气系统、地形等因素对暴雨形成的影响,以及河北省暴雨洪水特性,对境内中小河流防洪现状存在问题进行了初步探讨。研究认为,与自然因素相比,人类活动才是影响河道防洪主要因素。基于上述认识,针对中小河流防洪减灾对策,提出了应通过制定防洪规划和治导线规划等工作尽快划定河道行洪范围,逐步修建工程措施提高沿河保护区的防洪标准,同时采取多项非工程措施来加强管理、限制人类活动、规范水事秩序等,使各中小河流防洪体系逐步完善,为保护河道沿岸经济发展的成果和人们稳步进入小康社会提供保障。

[Abstract]
Lots of medium and small rivers exist in Hebei Province, and flood disaster is one of the main natural disasters restricting the rapid development of social economy and threatening people's lives and property security. Based on the analysis of effects of r the source of water, weather system, and topography on the formation of rainstorm and flood characteristics in Hebei Province, the present situation of flood control problems in the small and medium-sized rivers were discussed. The results showed that human activities are the main factor affecting the flood control compared with natural factors. On this basis, as for the flood control and disaster reduction countermeasures in small and medium-sized rivers, the scope of river flood needs to be defined through the flood control planning and regulation line planning, the engineering measures are improved gradually and the flood control standard in the protection area along the river is increased, and a number of non-engineering measures are adopted to strengthen river management, restrict human activities, and regulate water order, which can improve the flood control system in the small and medium sized rivers, and therefore ensure the economic development along the river and improve people’s living standards to entering into well-off society.
