摘　　要：基于城市综合流域排水系统,通过构建片区洪涝水文模型,对广州市浅山区地块所在排水分区进行仿真暴雨模拟分析,并开展洪涝风险研究,评估结果表明项目范围开发后的洪涝风险等级较低。同时基于评估结论与建议,严格遵从河涌规划管控线及管理范围线要求,落实区域防洪排涝设施及海绵调蓄空间管控,制定合理的竖向高程管控与雨水工程方案,保障片区安全合理地开发,确保城市土地资源可持续利用和韧性安全。研究可为广州市浅山区类似土地类型的用地适应性评估提供经验与借鉴。Based on the drainage system of the urban comprehensive drainage basin,the simulation of rainstorm was carried out in the drainage area of the shallow mountain area in Guangzhou city by building a regional flood hydrological model,and the flood risk study was carried out.The evaluation results indicate that the flood risk level after the development of the project scope is relatively low.Based on the evaluation conclusions and suggestions,strictly adhere to the requirements of the river planning control line and management scope line,implement the control of regional flood and drainage facilities and sponge storage space,develop reasonable vertical elevation control and rainwater engineering plans,ensure the safe and reasonable development of the area,and ensure the sustainable use and resilient safety of urban land resources.The study can provide experience and reference for land adaptability assessment of land types such as shallow mountain areas in Guangzhou City.
