基于低影响开发的天津市绿色雨水基础设施应用研究

城市雨水的收集与利用是实现城市可持续发展,保护城市水文特性的重要途径之一.针对天津市降雨及建设规划特点,以该市某居民小区雨水利用工程为例,对雨水利用技术进行了优化分析,提出基于低影响开发理念的雨水综合利用系统建设构想,并通过计算提出了适用于天津市的绿色雨水基础设施建设规模.分析了该设施应用效果及控制参数选择,研究结果可为城市住宅小区的雨水利用系统规划建设提供参考依据.

Developing Low-Impact Green Stormwater Infrastructure in Tianjin City

The collection and utilization of urban stormwater is not only an important part to achieve sustainable development of water environment,but also an effective way to protect urban hydrological features.Based on the characteristics of rainfall and urban planning in Tianjin City,a case study was conducted in anurban subdivision in regard to optimizing the technologies of stormwater utilization.The construction tentative plan of stormwater utilization was discussed based on the concept of minimum impact.The feasible scaleof green stormwater infrastructure is proposed to meet the needs of the City.Furthermore,applied effectsand control parameters were analyzed to provide a reference basis for planning and construction of rainwaterutilization system in urban residential areas.
