摘要: 生态城市规划领域中较为成熟的量化分析方法能够为海绵城市规划研究提供重要借鉴。在提炼生态城市规划和灾害威胁 下建设用地规划研究框架的基础上,以长春为例,从多层筛选的视角探索基于敏感性和适宜度分析的海绵型场地选址研 究方法。以TOPMODEL模型为核心进行水文敏感性的指数化计算,划定水文敏感区和水文低敏感区;通过综述国内外雨 洪管理体系内涵与目标的发展历程,选定人口密度、空间整合度和城市蓝绿系统3个适宜度评价影响因子,并基于GIS的多 因子加权分析法进行海绵型场地适宜度评价,将建设区域分为最适宜、较适宜等5类用地;最后将敏感性与适宜度分析进 行叠加,选取具有最高敏感性和最高、较高适宜度的区域为海绵型场地选址区。以安全、社会、经济、生态等多价值提升为 目标构建可视化的海绵型场地选址研究方法,为海绵城市在城市规划层面的实现提供了新思维。

Abstract: The scientific quantitative analysis methods coming from ecological planning can be reference for sponge city. Taking Changchun as the research object, we explore the research method of identifying sites for sponge space based on analysis of sensitivity and suitability from multi-level filtering perspective. TOPMODEL is chosen to analyze hydrological sensitivity which is based on calculation of topographic index. Through reviewing development process of connotation and objective of rain-flood management system, three factors of population density, spatial integration and urban green system are ultimately selected for suitability evaluation. Based on analysis of sensitivity and suitability, we identify the areas with highest sensitivity and highest, higher suitability as the sites for sponge space. The visualized model of identifying sites for sponge space has been built, providing city managers with scientific and quantitative analysis.
