- Abstract:
- 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; Ⅱ. quantitatively analyze the engineering performance of construction tasks and their contribution to planning objectives, and evaluate the feasibility and effectiveness of the scheme; Ⅲ. 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.
