南京滨江公园绿地冬春季温湿度调节能力研究

Temperature and Humidity Regulation Capacity of Urban Green Spaces of Nanjing Riverside Park in Winter and Spring

文章以南京滨江公园为例,在2016年1月、3月和5月对绿地微气候环境的气象数据进行定量监测,探讨绿地在冬春季的温湿度调节能力。结果表明:绿地的温湿度调节能力具有较显著的季节性差异,1月份的降温增湿强度最为明显,5月份次之,3月份表现则较一般;不同景观类型的微气候环境温湿度调节情况也有差异,水边的样地降温增湿效益最大,其次为绿地和有透水铺装的样地;但是1月份的温湿指数要明显低于3月份和5月份,人的体感为冷、不舒适。该研究对于绿地在改善南京冬春季节的微气候舒适度有一定参考意义。

Taking Nanjing Riverside Park as an case study,the paper quantitatively measured the climatic data of the green space microclimate in January,March and May 2016 and discussed the green spaces＇ capacity to regulate the temperature and humidity in winter and spring. The results indicated that the green spaces showed seasonal variation in their capacity for temperature and humidity regulation,which was strongest in January,followed by May and March; the regulation capacities in various types of microclimate also showed differences,the waterfront area showing the largest benefits for temperature decrease and humidity increase,followed by green spaces and the area permeable pavement; the Temperature-Humidity Index（ THI） in January was obviously lower than those in March and May,which makes people feel cold and uncomfortable. The research could have some references to improve microclimate thermal comfort with green spaces in winter and spring.
