摘　　要：随着海绵城市建设从规划阶段向实施阶段的过渡,建设思路也由单一海绵项目发展为片区整体解决方案。小流域海绵城市系统化方案采用系统化的思维,对现有海绵规划设计进行优化和统筹,可转变规划设计思维,按照海绵城市建设的总体要求,统筹安排各项建设任务;量化分析建设任务的工程绩效和对规划目标的贡献程度,评估方案的可行性和有效性;深化规划的落实和设计的统筹,明确工程措施与海绵绩效的关系,整合优化海绵建设任务,提高工程的实施效率和效果。以某小流域为例,针对该流域的重点问题,提出了自然本底保护、水环境治理和水安全提升三方面的海绵建设策略,并通过模型评估等技术手段,对方案的实施效果进行了量化评估。该研究成果可为类似小流域海绵城市系统化方案编制提供参考。With the construction of sponge city from the planning stage to the implementation stage,the construction method has also developed from a single sponge project to the overall solution for the region.The systematic planning scheme of sponge city in small watershed adopts a systematic thinking to optimize and coordinate the existing sponge planning and design,and achieves the following purposes:I.change the planning and design thinking,and arrange the construction tasks according to the overall requirements of the sponge city construction;I.quantitatively analyze the engineering performance of construction tasks and their contribution to planning objectives,and evaluate the feasibility and effectiveness of the scheme;II.deepen the planning implementation and design coordination,and clarify the relationship between the engineering measures and the sponge performance,integrate and optimize the sponge construction tasks,and improve the efficiency and effectiveness of project implementation.Taking a small watershed as an example,this paper proposes three sponge construction strategies including natural background protection,water environment management and water safety improvement.This paper also uses technical means such as model evaluation to quantitatively evaluate the implementation effect of the scheme.The research results can provide reference for the compilation of systematic planning scheme of sponge city in similar small watershed.
