天津市五大道历史文化街区绿色空间空气质量和温湿度调查研究

Investigation on Air Quality and Temperature-Humidity of Green Space in the Wudadao Historical and Cultural Area in Tianjin

绿色空间是历史文化街区的重要生态保障。为探究历史文化街区中绿色空间的生态价值,以天津市五大道历史文化街区为研究对象,针对绿色空间的类型及绿化指数、悬浮颗粒及负氧离子浓度、温湿度进行实地调研和数据分析。结果表明:良好的植被覆盖和复层植被结构对净化空气、增加负氧离子浓度、降低空气温度、提高相对湿度等具有积极影响。研究旨在为历史文化街区中绿色空间的规划与设计提供科学参考与指导。

Green space is an important ecological safeguard for historical and cultural area. To explore the ecological value of green space in the historical and cultural area, the paper selects the Wudadao Historical and Cultural Area in Tianjin as the research subject. Field research and data analysis are conducted on green space type and greening index, suspended particles and negative oxygen ion concentration, and temperature-humidity. The result indicates that good vegetation cover and layered vegetation structure have positive effects on purifying the air, increasing the negative oxygen ion concentration, reducing the air temperature and increasing the relative humidity. The research aims to provide scientific reference and guidance for green space planning and design in the historical and cultural area.
