摘要:
近年来我国城市内涝频发,雨季“看海”情况屡见不鲜,而目前对于内涝程度还没有统一的评价指标体系,为了得到更加完善的海绵城市内涝程度评价指标体系,基于城市内涝动态历时特征,提出内涝势冲量的概念,建立城市局部内涝瞬时指标、局部内涝综合指标、区域整体内涝指标标准值等组成的评价城市内涝程度的指标体系及其具体计算分析方法. 针对宁波市奉化区中交未来城工程案例,结合SWMM模型计算该区域内涝情况,并采用此评价方法进行分析. 结果表明:计算的局部内涝综合指标能有效反映城市内涝点的内涝程度,其内涝设计值可以有效评价城市整体内涝程度;计算的区域整体内涝程度指标平均值能描述LID(低影响开发)措施防涝设计的总体合理性,并且指标体系能有效反映内涝的时空分布特征,指标值采用无量纲量,评价方法更加科学.

Abstract:
Urban waterlogging disasters frequently occur in China in recent years, and “Seeing the Sea” is very common in the rainy season. However, there is no unified evaluation index system to assess the degree of urban intrusion. In order to get a more complete evaluation index system of waterlogging degree of sponge city, the concept of the momentum of waterlogging potential energy was introduced based on the dynamic duration characteristics of urban intrinsic temporality. The indexes system for the evaluation of urban intrinsic degree, including the local indicatory instantaneous index, the local indwelling comprehensive index, the regional overall indifference index standard value, and the corresponding calculation and analysis methods were established. The Zhongjiao Future City in Fenghua District of Ningbo City was taken as a case. The SWMM model was used to calculate the intrinsic conditions in the region. Results show that the calculated local indwelling comprehensive index can effectively reflect the degree of internal flaws and the internal flaw design of the city. The value could evaluate the degree of the city’s overall internality. The calculated average of the region’s overall internal level can describe the overall rationality of the flood prevention design of the LID (low-impact development) measures, and the index system can effectively reflect the spatial and temporal distribution characteristics of the internal plutonium. Adopting dimensionless quantity, the evaluation method is proved more scientific.
Key words:  momentum of waterlogging potential energy  sponge city  degree of intrusion  evaluation method  LID measures
