摘　　要：为进一步认识和推广海绵城市建设,有必要进行海绵城市以及不同海绵设施的经济、生态和社会效益研究,从而优化海绵城市的综合效益,达到提高公众满意度的目的。为此,邀请国内外海绵城市领域专家参与针对28个海绵城市建设效益指标的重要性排序以及21种海绵设施社会效益主观评价的问卷调查,其中,对海绵城市有深入了解的受访专家占比达75%,从事海绵城市研究、规划、设计及管理方面工作的专家占91%。调查结果显示:在进行海绵城市规划设计时,重要性位居前五的效益指标分别为降低雨水径流进入城市水体前污染物浓度、减少雨污合流制溢流污染、提高城市美化度、提高周边居民居住舒适性和回补地下水,得分均值分别为7.8、7.2、7.1、6.8和6.7分(最高10分);专家对海绵城市的了解程度越高,效益指标的重要性评分也越高;从事海绵城市相关工作的专家中,管理人员最看重海绵城市建设的性价比,更希望以最低成本获得最大效益;雨水花园等水绿复合型海绵设施的社会效益普遍优于渗管/渠等灰色基础设施。In order to better understand sponge city and further its construction, it is necessary to investigate economic, ecological and social benefits of sponge city and its measures, so as to optimize comprehensive benefits of sponge city and improve public satisfaction. Therefore, domestic and overseas experts in the field of sponge city were invited to participate in a questionnaire survey on the importance of 28 benefit indicators of sponge city and the subjective evaluation of social benefit of 21 sponge city measures. Among the experts, 75% of them had in-depth knowledge of sponge city, and 91% of them were engaged in sponge city research, planning, design and management. For the sponge city planning and design, the top five important benefit indicators were as follows: reduction of pollutant concentration in urban runoff before entering the receiving water body, reduction of pollution from combined sewer overflows, increase of urban aesthetics, improvement of the living comfort of surrounding residents and recharging groundwater, and the average scores on these indicators were 7.8, 7.2, 7.1, 6.8 and 6.7(the maximum point is 10), respectively. The expert with a higher level of familiarity gave a higher score of benefits. Among the experts engaged in the sponge city related work, the management personnel valued the cost-effectiveness ratio of the sponge city construction the most and desired to obtain the maximum benefits at the lowest costs. The social benefits of green infrastructures such as rainwater garden were generally superior to those of grey infrastructures such as infiltration pipe/trench.
