城市高楼林立,绿地面积有限,楼顶花园便成为不可多得的绿色宝地。尤其是炎热的夏天,楼顶花园可减少,太阳辐射,降低高楼建筑区的温度,增加湿度,调节大气中氧气和二氧化碳的比例,净化空气和调节小气候,等等。人们不出大楼,就可以找到游憩的花园,岂不美哉?但是,修建楼顶花园必须注意建筑物的承荷力,确保安全。最好在房屋建筑设计时,就把楼顶花园考虑进去。 There are many high-rise buildings in the city, and the green space is limited. The garden on the roof will become a rare green treasure. Especially in hot summer days, rooftop gardens can reduce solar radiation, lower the temperature of high-rise buildings, increase humidity, regulate the proportion of oxygen and carbon dioxide in the atmosphere, purify the air and regulate the microclimate, and so on. If people don’t come out of a building, they can find a garden that is not very beautiful. However, building a roof garden must pay attention to the building’s load-bearing capacity and ensure safety. It is best to take the roof garden into consideration when designing a house.
