And then the root system in the covering soil can damage the floor slab, so special technical measures such as a root-resisting layer and the like are needed, and the cost is difficult to control. In addition, the summer is difficult to maintain, the hot sun needs to be watered every day, but the evaporation capacity of the ground surface is far greater than the transpiration capacity of plants, so that great water resource waste is caused. These all result in the current roof planting and roof garden being too expensive to deploy.
The rainfall is not fully collected and utilized at present, and the rainfall is discharged one by one, which causes great roof water resource waste. Under the global warming large environment, the heat island effect and the rain island effect of summer cities are more and more remarkable. If can fully collect the rainfall on roof and utilize in the roof planting, not only can reduce the absorptive a large amount of solar radiation heat in roof to reduce the air conditioner and use, can also utilize the roof vegetation of the city large tracts of land and facility retaining to slow down the aggravation effect of rainfall to the urban waterlogging, play the effect of heat absorption and sponge that absorbs water, cooperate the heat tide of present sponge urban construction, build the city of sponge in the air, this is to the sponge urban engineering transformation of old residential area more significant.
