| 摘要: |
| 在分析流域、区域、城市防洪工程作用的基础上,提出以11项骨干工程为核心组成太湖流域防洪体系,其主要作用是在设计条件下保证流域整体防洪安全,并建议按流流域GDP的0．2%-0．3%洪灾损失作为判断和控制流域性洪灾的经济指标．根据太湖流域防洪标准的基本涵义,讨论了设计暴雨时空分布与流域防洪体系规划建设的关系．最后,在分析太湖流域现状防洪标准的基础上,从防洪减灾角度,提出提高流域防洪能力的建议． |

| Abstract: |
| According to the analysis on basin，regional and urban flood control projects in Taihu basin, the basin flood control system mainly consist of 11 key engineerings and its function is to ensure safety of Taihu basin under the design flood conditions. The critical value of flood loss to equal 0. 2%-0. 3% GDP of the basin is regard as a index judging and controlling basin flood disaster. Based the meaning of flood control standards for Taihu basin,relationship between space-time distributing of design storm and planning of the flood control system are analysed. Lastly, the practical flood control standards of the basin is discuss and some suggestions are put forwarded to increase basin flood control capacity. |
