China is the world's most populous country, little green space per capita, as China's rapid economic development, urbanization, increasingly dense urban population, building an increasingly crowded, Lanzhou roof garden pieces, increasing the city downtown, urban per capita green area will occupy less and less green roof is undoubtedly the best way to resolve this contradiction. Green roof experience of Germany, Japan, the United States and other countries is worth our reference, to rapidly improve the quality of urban environment, beautify the urban environment will undoubtedly have a positive role in promoting. Recently it has been from the urban ecosystem perspective on the future of cities proposed several ideas. One idea is stepped cities, namely floors of city buildings of different heights, Lanzhou Feng Shui roof garden, and the roof of a building higher buildings constructed another building's roof garden or orchard, vegetable, green, etc. ??? This vision is to make full use of the roof space green roofs, green space and natural factors increase the city, to protect and improve the urban environment, improve the urban ecosystem, the purpose of promoting urban economic, social and environmental development. The system is developed on the basis of the original waterproof design, shown in Figure 1, which overcomes the shortcomings of the waterproofing membrane, Lanzhou roof garden, and use of the thermal insulation layer is characterized as planting. Its rationale is both the vegetation off the soil earth layer, drainage layer, but also play a water absorption, thermal insulation and protection of the roof to find the effect of slope layer or base layer. Carbon dioxide absorbed by vegetation indoor discharged Lanzhou roof garden planning, exhale oxygen, and also the absorption of moisture in the soil off. Because the vegetation can absorb heat from the sun radiation into biochemical energy through photosynthesis, thereby changing the form of energy exists. Also its surface reflects heat small, long-wave radiation, winter and good insulation properties, so the vegetation also has good thermal performance.
