- Abstract
Urban green space is considered an important part of urban ecological construction be-cause of the efficiency of green space in reducing ambient temperature. It was previously reported that the quantity and layout of arbors and paving are very important factors for cooling. To research the combination mode of the quantity and layout of arbors and paving able to effectively lower the temperature during the summer in a coastal open space environment where little architecture exists, we built a numerical model of heat transfer using ENVI–met numerical modeling simulation, for which the May Fourth Square in Qingdao was selected. The results showed that the ratio coverage of the arbor layer and pavement fragmentation were positively correlated with the cooling effect. We found that setting the passageway conformed to the sea breeze by arbors and close planting at the air outlet effectively reduced the site temperature. After optimizing the site's greening layout, the cooling effect over the process of time decreased in the height direction. At the same time, the cooling effect increased before 15:00 and then reduced gradually in the time dimension. Compared to the original site, the total cooling efficiency reached 1.41 × 108 J, equaling electric energy of about 39.2 kW·h. This research solves the issue of the synergy between planting and pavement for cooling coastal open spaces in summer and provides a basis to formulate a promotion strategy for landscape design areas with similar geographical and climatic conditions.
