城市河流防洪能力提升对策分析

Analysis on Upgrading Countermeasures for Flood Control Capacity of Urban Rivers

受气候变化和人类活动影响,洪涝灾害多发重发的态势愈发强烈,城市河流的防洪保安能力制约了城市经济社会的高质量发展,必须完善水利基础设施中的薄弱环节,筑起保障人民生命财产安全的牢固防线。为研究城市河流在防洪能力提升过程中的治理对策,以某城市河流为例,考虑增加调蓄区容积、退建加高河流堤防、增加泵站外排能力等措施。结合城市发展需要,分析不同措施的优劣性和可行性,综合提出城市河流治理的设计方案,对比各方案实施的效果、影响、投资、难度、管理等因素,综合选定治理对策。

Under the influence of climate change and human activities,the situation of repeated flood disasters is becoming more and more intense.The flood control and security capacity of urban rivers restricts the high-quality development of urban economy and society.It is necessary to improve the weak links of water conservancy infrastructures and build a solid defense line to protect the safety of people’s lives and property.In order to study the countermeasures of urban rivers in the process of upgrading the flood control capacity,taking an urban river as an example,the measures are considered for increasing the volume of regulation and storage area,reconstructing and heightening the river dike and increasing the discharge capacity of pumping station.Combined with the needs of urban development,the advantages,disadvantages and feasibility of different measures are analyzed,and the design scheme of urban river governance is put forward comprehensively.The effect,impact,investment,difficulty,management and other factors in the implementation of each scheme are compared,and the control countermeasures are selected comprehensively.
