道路扬尘控制措施及其效率评估研究进展

Research progress of road dust control measures and their efficiency evaluation

  • 摘要: 道路扬尘是当前我国城市交通排放PM10的主导来源。因此,采取有效措施控制道路扬尘,并对其控制措施效率进行评估,不仅是城市大气环境管理中的重要一环,而且对于高效精准地削减道路扬尘排放量具有重要意义。综述了国内外文献报道的主要道路扬尘控制措施的原理、特点、应用范围和发展历程,在此基础上介绍了不同研究对各类控制措施效率的评价方法和评估指标,分析比较不同控制措施的有效性,并对影响控制措施效率的因素进行了系统的总结和评述。指出当前国内缺乏符合我国实际道路基础设施、气象气候条件和城市环境管理措施的相关研究,未来可考虑将新型道路扬尘检测方法TRAKER与已形成标准的AP-42法联合应用于构建一个评估控制措施效率的衡量体系,以便确定最为经济和高效的道路扬尘控制措施,为城市日常环境管理提供参考建议。

     

    Abstract: Road dust is currently the leading source of PM10 emissions from urban traffic in China. Therefore, taking effective measures to control road dust and evaluating the effectiveness of the control measures play an important role in urban atmospheric environmental management, and have great significance for efficiently and accurately reducing road dust emissions. The principle, characteristics, application scope and development history of main control measures on road dust reported in domestic and foreign literature were reviewed. On this basis, the evaluation methods and indicators of various control measures in different studies were introduced, and the effectiveness of different control measures was analyzed and compared. The factors affecting control efficiency were also systematically summarized. It was pointed out that there was a lack of relevant research in China, which met the country’s actual road infrastructure, weather and climate conditions, and urban environmental management measures. In the future, it could be considered to combine the new road dust detection method named TRAKER with the classic method named AP-42 to construct a measurement system for evaluating the efficiency of control measures, so as to determine the most economical and efficient road dust control measures and provide suggestions for urban atmospheric environmental management.
