| 摘要: |
| 为探究城市洪涝背景下的地区海绵城市潜力评估方法，从海绵城市最具相关的降雨量、水污染、洪涝灾害和生态绿地4个方面展开，构建海绵城市潜力指标体系，以国家级天府新区为例，运用数理统计、模糊神经网络、模糊综合评价、卫星图像识别等方法对地区指标体系进行综合研究，采用灰度关联分析法对天府新区海绵城市建设潜力定量评价，并给出各区县海绵城市潜力指数排名，最后针对洪涝灾害研发新型排水系统.研究结果表明：与实际情况对比可发现从降雨量、水污染、洪涝灾害和生态绿地等4个方面评价地区海绵城市潜力结果较为客观；双流片区指标向量与理想指标向量关联度最小，是天府新区中最具有海绵城市建设潜力的地区；研发的地下排水系统在一定程度上能够缓解城市内涝、水质和管网压力等问题，所提出的海绵城市潜力方法和地下排水系统可为推动海绵城市建设提供参考.

| Abstract: |
| To explore the potential evaluating methods of regional sponge city under the context of urban flood, this paper establishes the potential indicator system of sponge city from the perspectives of rainfall, water pollution, flood disaster and ecological green land. Because these four elements are closely related with sponge city. Taking the national-level Tianfu District as an example, the regional index system is studied comprehensively by using the methods of mathematical statistics, fuzzy neural network, fuzzy synthetic evaluation and satellite image recognition; besides, the construction potential of Tianfu District sponge city is evaluated with the methods of gray correlation analysis quantitatively; moreover, the potential index ranking of every sponge city in every district and county is given. Finally, a new drainage system is developed according to flood disaster. The results show that it is relatively objective to evaluate the sponge city potential from the above four aspects, namely, rainfall, water pollution, flood disaster and ecological green land; also, the indicator vector of Shuangliu Area has the minimum correlation with the ideal indicator vector, which means this area is the most proper and potential place to carry out the sponge city construction in Tianfu District; furthermore, the developed underground drainage system can alleviate problems of city waterlogging, water quality and pipe network pressure and so on. The mentioned evaluating methods of the potential of sponge city and the developed underground drainage system can provide references for promoting the construction of sponge city.
