As the contradiction between building land and green space increasingly intensifies in recent years, roof greening, a combination of architecture and greening art, has become a new way of urban afforestation.
As of 2012, Beijing's roof greening area had already amounted to more than 1.2 million square meters, about 1 percent of the total area of Beijing urban roofs, according to the Beijing Rooftop landscape Association.
Roof greening usually involves building roofs as well as balconies. Roof greening can beautify the city, improve the urban ecological environment, save natural precipitation, relieve the heat island effect and increase the quantity of urban green space and visible green space.
