高密度城市暴雨洪涝治理理论框架及其应用研究

Theoretical framework and application of urban rainstorm flood control in high-density cities

高密度城市洪涝高标准设防与用地高度紧张矛盾突出。本文通过分析传统洪涝治理模式特点及其应用于高密度城市的局限性,从目标、内涵、方法等三个层次,构建了高密度城市暴雨洪涝治理理论框架,破解了传统洪涝分治模式难以实现洪涝防治标准大幅提升和系统达标的难题。将上述理论框架应用于深圳市深圳河流域,开展了实证研究,其结果表明,运用本理论框架进行洪涝治理工程规划设计,既满足高密度城市化地区经济性和约束性原则,又能实现洪涝共治、系统达标,可为我国城市洪涝治理提供新的思路和借鉴。

Contradiction between high standard of urban rainstorm flood prevention and intensive land uses in high-density cities is significant.The characteristics and limitations of traditional flood control mode were analyzed,and a new theoretical framework of urban rainstorm flood prevention in high-density cities was proposed.The framework includes three levels:objectives,connotation and methodology.Because it is difficult for the traditional flood management mode to significantly improve the urban rainstorm flood prevention standard,authors in this study proposed a new solution in this theoretical framework.The Shenzhen River basin in Shenzhen City was selected as the study area,and the case study was carried out in this paper.The results showed that the planning and design of urban rainstorm flood prevention projects by using this framework can not only meet the economic and restrictive principles in high-density urbanization area,but also achieve the joint prevention of urban rainstorm flood,and satisfy the overall standard.The practice that this theoretical framework can provide a new theoretical basis for urban rainstorm flood prevention in China.
