Research on Adaptive Design Strategy of Hangzhou Streets Based on Summer Micro-climate Effect

As urban heat island effect is becoming increasingly serious, the study of climate in small-scale public space has turned into a hotspot of landscape architecture discipline. In this study, we have selected Wenyi West Road and Gudun Road of Hangzhou as the measured objects. We measured the air temperature, relative air humidity, solar radiation intensity and wind speed and direction of the space of each measurement point in August 2017, to analyze the daily changes of the microclimatic factors. We have adopted the Rayman1.2 model to evaluate the differences in human comfort, and put forward targeted adaptive design strategies for microclimate in street space. The study finds that we should manage to set streets in orientation parallel or close to the dominant wind of the city, construct more shading space to regulate the microclimate of street interface in consistency, add road central interface landscape with plants or green building materials, plant deciduous and evergreen trees in five green belts to separate sidewalks, non-motorized vehicle lanes and motorways, select the arbor-shrub-grass layered structure, while adding vertical greening, to effectively alleviate the extreme heat sensation in summer, and create a comfortable, healthy urban street space.
