山东日照海绵城市专项规划编制思路探索

Exploration on Compiling the Sponge City Special Planning: A Case Study of Rizhao City,Shandong Province

在我国海绵城市建设过程中,海绵城市专项规划起到重要的引领和统筹作用。以山东日照市海绵城市专项规划为例,探索海绵城市专项规划编制的基本原则和总体思路。在编制日照市海绵城市专项规划时,首先在现状调研的基础上识别出规划区存在的主要问题,提出规划目标并建立了海绵建设指标体系;然后,从城市自身及周边的生态环境本底特征出发,通过优化城市生态格局保障城市生态安全,构建了海绵城市空间格局;最后,针对规划区内水体黑臭和内涝频发的问题,按照灰绿结合的原则提出了系统化的解决方案;同时将总体目标分解到28个管控单元,制定针对性的海绵管控指标和控制策略,为海绵城市建设管理及控制性详细规划的落实提供技术支持。

In the construction of the sponge city in China, the sponge city special planning plays an important role in guiding and overall planning. Taking the sponge city special planning in Rizhao City as an example, this paper introduced the basic principles and general ideas of compiling the sponge city special planning. After the main issues concerning the sponge city are identified based on the investiga- tion, the planning targets were put forward and an index system of sponge city construction was estab- lished. And furthermore, based on the ecological environment of the city and its surrounding background characteristics, the city ecological security was safeguarded and the sponge city spatial pattern of Rizhao City was built through optimizing the ecological security pattern. Moreover, with respect to black and odorous rivers and frequent waterlogging, systematic solutions were put forward in accordance with the I principle of combining gray and green infrastructure. Finally, after the overall goal was decomposed into 28 control units, the specific sponge city control indexes and control strategy were made, which could provide technical support for the construction or management of the sponge city and the implementation of the regulatory detailed planning.
