摘　　要：针对目前城市路面径流水量水质雨水口原位监测存在的径流漫汇流、雨水口空间狭小、环境干扰大和降雨时空随机性等问题,研发了一种基于机械双稳态翻斗结构、结合紫外-可见光光谱的城市路面径流水量水质雨水口原位自动监测系统,实现了雨水口原位水量水质连续自动监测。率定及评估结果表明,该监测系统可操作性强、空间适应性高,可获取逐分钟雨水口原位水量水质数据,满足径流量为1~200 L/min的监测需求,修正后翻斗动态计量相对误差小于5%,可适用于不同类型降雨径流监测,为城市路面径流雨水口原位监测和径流污染研究提供技术参考。This paper developed an automatic monitoring system for urban pavement runoff quantity and quality at gutter inlets based on a mechanical bistable tip‑bucket structure combined with UV‑visible light spectrum,which realized continuous automatic monitoring of runoff quantity and quality in‑situ at gutter inlets,so as to solve the existing challenges such as runoff confluence,limited space of gutter inlet,significant environmental disturbance and spatio‑temporal variability of rainfall.The calibration and evaluation results demonstrated that the monitoring system exhibited robust operability and high spatial adaptability.It was capable of acquiring in‑situ runoff quantity and quality data from the gutter inlets every minute,meeting the monitoring requirements for runoff flows ranging from 1 L/min to 200 L/min.The relative error of the modified tipping bucket dynamic measurement was less than 5%,rendering it suitable for monitoring various types of rainfall runoff.The system provided valuable technical guidance for in‑situ monitoring of urban pavement runoff at gutter inlets and controlling runoff pollution.
