中文摘要:
      目的 研究濒海大气环境氯离子沿建筑物高度的分布规律。方法 以海南濒海高层建筑为研究平台,在建筑物不同高度楼层设置监测点,采用“纱布法”完成不同高度层的大气环境氯离子沉积速率数据采集,每次取换样周期为30 d,连续监测1 a。利用离子色谱仪对所采集的样本进行检测分析,研究濒海大气环境氯离子沿建筑物高度的分布规律。结果 氯离子沉积速率随塔楼高度的增加而升高,在塔楼建筑高度60%~70%的区域,受到高层建筑“下冲风”的影响,氯离子沉积速率会有所下降,出现相对低值。通过这个区域后,氯离子沉积速率又逐渐升高。结论 濒海大气氯离子沉积速率沿建筑物高度变化规律受到大气氯离子浓度、风向风速、温湿度和高层建筑气流的综合影响。
英文摘要:
      The work aims to study the distribution law of chlorine ions along the height of buildings in the coastal atmosphere. With coastal high-rise buildings of Hainan as the research platform, monitoring points were set at different floors of the buildings, and the “gauze method” was used to collect the chlorine ion deposition rate in the atmospheric environment at different heights. Each sampling and changing cycle was 30 days, and the continuous monitoring time was 1 year. The collected samples were detected and analyzed by ion chromatograph to study the distribution law of chlorine ions along the height of buildings in the coastal atmosphere. The chloride ion deposition rate increased with the height of the tower building. In the area of 60%-70% of the height of the tower building, the chloride ion deposition rate decreased to a relatively low value due to the effects of the “downwind” of high-rise buildings. After passing through this area, the chloride ion deposition rate gradually increased. The change of chloride ion deposition rate along the height of buildings in the coastal atmosphere is affected by the overall influence of atmospheric chlorine ion concentration, wind direction and wind speed, temperature and humidity and high-rise building airflow.
