摘要
城市环境中自然通风源于城市热压梯度及城市风压梯度的综合作用。城市环境中自然通风影响着城市"五岛"效应(城市热岛、湿岛、干岛、浑浊岛及雨岛),城市大气的自净能力和城市居民的身体健康,也是研究快速城市化地区广义城市风环境(风场、温度场、湿度场)的参考因子。为了全面理解国内外针对城市环境中自然通风的研究进展,从城市环境中自然通风的监测、模拟及应用三个方面对目前国内外针对城市环境中自然通风的研究现状进行了综述,最后结合环境物联网、无线传感技术等目前在城市环境中自然通风研究的相关技术及应用领域的新进展,对城市环境中自然通风的后续研究热点和关键问题进行了展望,为城市环境中自然通风的相关技术及应用问题的后续研究提供了基础研究素材。
Natural ventilation in urban environment is driven from urban thermal gradient and wind pressure gradient. Natural ventilation in urban environment affected urban ＂Five Island＂ effect including urban heat-island, urban moisture- island, urban dry-island, urban cloudy-island and urban rain-island, as well as self-purifying ability of the natural urban atmosphere and the health of urban residents very much, which also is the effective factors in study on broad sense of urban wind-environment. In order to review the progress of study on natural ventilation in urban environment systematically, the monitoring, simulation and application of natural ventilation in urban environment were taken into consideration, and natural ventilation in urban environment based on the advanced development of related technologies, such as the internet of environmental-things and wireless-sensor technology was reviewed, which provied information source for relative technology and application study on natural ventilation in urban environment.
