城市化进程带来城市不透水地表的快速扩张与不合理空间布局加剧城市暴雨内涝灾害。在中国城市发展从增量用地的规模扩增转变为存量用地的内涵提升背景下，大幅减少不透水地表面积的做法不符合城市发展进程。借助城市更新契机，在城市更新规划阶段即进行不透水地表的优化设计是实现城市暴雨内涝根本防治的重要途径。当前，城市更新背景下不透水地表空间优化的相关技术包括减少不透水地表面积的低影响开发技术（LID）或基于蚁群算法的局部高强度不透水空间布局优化设计，这些技术存在耗时长、缺乏不透水地表优化设计方案的全局考虑等不足。本研究以广州市主城区为例，提出了基于多元线性规划算法与SCS-CN模型的不透水地表空间布局优化耦合模型（MLP-SCS），严格遵循城市规划单元要求划分城市径流小区为优化单元，以径流系数最小化为目标，进行各城市径流小区的不透水地表空间布局优化模拟。本模型可高效实现不透水地表空间布局的全局低强度优化，大幅缩减优化的计算时间，丰富了面向暴雨内涝防治的不同强度与规模的城市更新手段，为面向城市暴雨内涝防治的智慧城市更新规划提供参考，为综合考虑地下管网、河道、坡度以及雨水管理手段等因素实现空间规划视角下的城市群暴雨内涝防治提供了研究基础。
