铁路专用线声环境影响评价

针对新建铁路专用线沿线的环境特征，提出了铁路专用线声环境影响评价的程序、内容和方法。在目前缺乏新建铁路噪声预测模式的情况下，提出了应对铁路边界噪声、不同距离处的铁路噪声、敏感点噪声、鸣笛噪声进行预测，并以某铁路专用线声环境影响评价为例，对上述四种噪声进行了预测，通过预测得到铁路两侧的声环境状况，并以此为依据提出了铁路噪声的防治对策，以保证铁路专用线沿线声环境质量。

对美国FHWA公路噪声预测模式的深入讨论

美国ＦＨＷＡ公路噪声预测模式在我国被广为应用，甚至有各种修正模式，但因对原模式的理论依据仍缺少了解，以至在实际应用过程中或对原模式进行修正时诸如参数的选择及计算、模式适用范围等出现了不当或错误现象。本文从理论上对ＦＨＷＡ公路噪声预测模式进行了深入分析、进而讨论了各参数的物理意义、模式的适用范围，并提供了二种特殊情况下公路噪声的预测模式。

Insights into multidimensional transport flux from vertical observation and numerical simulation in two cities in North China

This study represents the first quantitative evaluation of pollution transport budget within the boundary layer of typical cities in the Beijing-Tianjin-Hebei (BTH) region from the perspective of horizontal and vertical exchanges and further discusses the impact of the atmospheric boundary layer (ABL)-free troposphere (FT) exchange on concentration of fine particulate matter (PM_2.5) within the ABL during heavy pollution. From the perspective of the transport flux balance relationship, differences in pollution transport characteristics between the two cities is mainly reflected in the ABL-FT exchange effect. The FT mainly flowed into the ABL in BJ, while in SJZ, the outflow from the ABL to the FT was more intense. Combined with an analysis of vertical wind profile distribution, BJ was found to be more susceptible to the influence of northwest cold high prevailing in winter, while sinking of strong cold air allowed the FT flowing into the ABL influence the vertical exchange over BJ. In addition, we selected a typical pollution event for targeted analysis to understand mechanistic details of the influence of ABL-FT exchange on the pollution event. These results showed that ABL-FT interaction played an important role in PM_2.5 concentration within the ABL during heavy pollution. Especially in the early stage of heavy pollution, FT transport contributed as much as 82.74% of PM_2.5 within the ABL. These findings are significant for improving our understanding of pollution transport characteristics within the boundary layer and the effect of ABL-FT exchange on air quality.
