摘要
低影响开发是海绵城市建设的核心,总结了绿色屋顶、植草沟和生物滞留槽等3项典型低影响开发措施的技术特点、实际效果与模拟研究进展,指导海绵城市建设中低影响开发措施的应用实践。主要结论如下:现有研究多为点尺度小范围研究,建议对各项措施的技术规格、适用性及实际效果进行全面系统地分析;应用推广较多,但缺乏实地效果监测与评价,有必要发展相关监测技术、设备,为低影响开发措施的径流减控与污染物削减效果评估提供支撑;由于监测工作的缺失,现有低影响开发措施的模拟结果大都缺乏实测数据的验证,影响到模型合理性与实用性评价,建议从实测数据详实的小尺度措施模拟开始,逐步进行低影响开发措施的模拟工作;为了合理设置低影响开发措施的组合,建议构建低影响开发技术优选体系。
Low Impact Development （LID） is the main idea of＂Sponge city＂. The technical characteristics, actual effects anti modeling process of green roofs, grass swales and bio-retention cells were summarized. The main conclusions are as follows： current study are mainly limited to point scale cases, we suggest the future systematic study should focus on the technical specification, adaptability and the actual effects of LID practices; considering the lack of assessment of LID practices, it＇s necessary to develop the technology of monitoring equipment; future more, the current modeling of LID practices are lack of verification, which affects the assessment of modeling rationality and practicability, therefore, we suggest that the modeling practices should start from the point scale cases with detailed measured data; systemic optimizations suggested here to determine the combination of LID practices.
