摘　　要：为优化城市道路与绿化体系的低影响开发设计方案,采用多目标规划优化方法,以总投资最低、污染最小、社会效益最大为目标,考虑多个约束条件,建立了一个多目标规划模型,并将北京市某组团7号路的实例代入验证.结果表明,该优化方法在工程造价仅增加8%的情况下,环境效益增加140%,社会效益增加了123%.研究验证了方法的适用性和有效性,为今后海绵城市建设中的道路规划提供借鉴.A multi-objective programming model is proposed in order to optimize the design of road and greening system with the low impact development facilities application.Three objectives including economic,environmental and ecological requirements is to obtain large investment interest,low pollution impact,more ecological benefit.The model considers multiple constraints and is solved based on the genetic algorithm.The results show that the optimization method increases the environmental benefits by 140%and the social benefits by123%when the project cost increases by only 8%.The research verifies the applicability and validity of the method by a case study of Group No.7 Road in Beijing and provides reference for the road planning in sponge city construction in the future.
