摘要
城市大面积的植被覆盖对城市环境尤其是热岛效应的积极作用已经成为常识,而人们却往往忽略了植被覆盖度及植物配置对于环境的温度及湿度的影响,推及到对人的一个服务作用。这方面也一直缺乏一个相关的调查及研究。选择苏州市20个不同地点作为样本,研究植物的遮阴度及配置对环境的温度及湿度的影响。结果表明:夏季的城市中,植物遮阴度较大时在局部区域内起到一个降温增湿的作用,而在植物配置方面,多植被区阻力较小,有助于空气流动从而也达到一个降温增湿的作用,在更大程度上吸引人群在此区域内活动休憩。
Vegetation covering over large areas in city plays a positive improving action to urban environment, especially heat island effect, but people tended to ignore the vegetation cover and plant configuration for the effects of temperature and humidity of the environment, and human living in the city. Moreover there was less survey on this aspect. By choosing 20 zones in Suzhou city as samples （tested objects）, the effects of plants shading degree and configurations on environment temperature and humidity were investigated. The results show that in summer in the city, larger area of plants with shaded in the local region played a role in cooling and humidification, while in the aspect of plant configuration, and more, air flow and thus contribute to achieve a cooling effect humidification, the high vegetation shading levels decreased of air temperature, the air flow resistance was less and beneficial for air flow thus playing a role of cooling and humidification in part of urban areas.
