中文摘要 该研究选择杭州学院路部分路段为研究对象,将其划分为4个长度为50 m的样地,并对各个样地街谷绿化进行详实的基础调查。该研究还对学院路绿化区域温湿度、太阳辐射等环境因子进行调查,同时分析人体舒适度指数等参数。结果显示:1)绿化能显著改善街谷温湿度和人体舒适度指数;2)多排乔木与灌草结合的绿化空间形式对改善街谷热环境有明显效果;3)绿化覆盖率越高降低铺装表面温度越明显,其中沥青铺装表面日平均降低温度最高可达18.5℃,花岗岩铺装表面降低温度最高可达17℃;4)选择样地3研究不同位置的太阳辐射强度、空气温湿度等参数,比较悬铃木和香樟两种树种的生态效益,发现悬铃木改善热环境的能力优于香樟。通过对比各个样地绿化对热环境的改善效果,得出街谷绿化优化建议,以期为街谷绿化建设提供依据。

英文摘要 The paper made an analysis of the current state that urban street canyon greening is lack of sufficient theoretical basis with the aim to find a solution to the poor habitat environment in the street canyon. In this study detailed investigation was carried out on the 4 sample plots with a length of 50m, which were divided from a selected section of the Xueyuan road. Then, this study investigated the environmental factors in the greened areas of Xueyuan road, such as temperature, humidity, and solar radiation, and analyzed the parameters including the human comfort index. The results showed:(1) The temperature, humidity and human comfort index of street canyon had been significantly improved with the greening; (2) The greening spatial form combining multiple row arbor, grass and shrub had obviously improved the thermal environment of street canyon; (3) The higher the greening coverage rate was, the lower the surface temperature of the pavement was. The surface temperature of the asphalt pavement could lower averagely by 18.5℃ through the greening, while the granite pavement surface could lower averagely by 17℃ in temperature; (4) By comparing the ecological benefits of 2 species of Platanus and Cinnamomum after obtaining the solar radiation intensity, air temperature, humidity parameters of different locations in Sample 3, it was found that Platanus is better than Cinnamomum in its ability to improve the thermal environment. The comparison of thermal environment improvement through greening in the 4 sample plots came to the suggestions for optimizing the greening of street canyon. This study is expected to provide basis for the street canyon greening.
