沧州市地处海河流域中下游,水资源严重短缺,深层地下水超采严重,生态环境恶化,水已成为制约经济社会发展的瓶颈。结合沧州实际,从城区、农田两方面论述了如何利用雨洪资源,雨洪资源控制利用,从两个方面着手:①城区主要采用蓄纳屋顶、路面等不透水面的径流于渗井或草坪,以回补地下水;②农田灌溉坚持点(水库、闸坝)、线(河渠、堤防)、面(蓄滞洪区、田间)兼顾,通过科学调度,在保证防洪安全的前提下,充分利用雨洪资源,达到改善生态环境的目的。提出了雨洪资源利用的措施和建议。
Cangzhou City is located in the middle and lower reaches of the Haihe River Basin, a serious shortage of water resources, severe over-exploitation of deep groundwater, deteriorating ecological environment, water has become a bottleneck restricting economic and social development. According to the actual conditions of Cangzhou, from two aspects of urban area and farmland, it discusses how to utilize the resources of rainwater and floods and control the utilization of rainwater resources. The two aspects are as follows: ① The urban areas mainly use impervious surface such as roof and road surface to run infiltration wells or lawns In order to replenish the groundwater. (2) Irrigation of farmland Adhere to the points (reservoirs and sluices), line (canal and embankment), surface (flood storage and detention areas and fields), and make full use of rain under the premise of ensuring flood control safety through scientific dispatch Hong resources, to achieve the purpose of improving the ecological environment. Put forward the measures and suggestions of rain flood resource utilization.
