摘 要
随着城市化进程的加快，城市内涝和水资源短缺问题日益突出，海绵城市建设为解决这些问题提供了新思路。本研究以基于海绵城市的公园雨水花园设计为切入点，旨在通过优化雨水管理策略提升城市生态系统的可持续性。研究选取典型城市公园为案例，综合运用文献分析、实地调研和计算机模拟等方法，探索雨水花园在径流控制、水质净化及景观营造中的作用机制。结果表明，合理设计的雨水花园能够显著减少地表径流量，有效去除悬浮物和污染物，并增强公园的生态服务功能。本研究创新性地提出了适用于不同气候条件的模块化雨水花园设计方案，同时结合数字化技术实现了对雨水管理效果的动态评估。研究成果为海绵城市背景下公园绿地的设计与规划提供了理论支持和技术参考，对推动城市水环境治理和生态修复具有重要意义。

Abstract
With the acceleration of urbanization, issues of urban flooding and water resource shortages have become increasingly prominent, and sponge city construction has provided a new approach to addressing these challenges. This study focuses on the design of rain gardens in parks based on sponge city concepts, aiming to enhance the sustainability of urban ecosystems through optimized stormwater management strategies. A typical urban park was selected as a case study, and a combination of literature analysis, field surveys, and computer simulations was employed to investigate the mechanisms by which rain gardens contribute to runoff control, water quality improvement, and landscape creation. The results indicate that properly designed rain gardens can significantly reduce surface runoff, effectively remove suspended solids and pollutants, and strengthen the ecological service functions of parks. Innovatively, this study proposes a modular rain garden design adaptable to various climatic conditions and integrates digital technologies for dynamic evaluation of stormwater management performance. The findings provide theoretical support and technical references for the design and planning of park green spaces under the sponge city fr amework, contributing substantially to urban water environment management and ecological restoration.
