  Green roof not only give the city to add greenery, the summer season also reduces heat radiation and heat island roof construction materials, but also can reduce air pollution, improve the urban environment. Data show that green roofs per square meter a year on average lag of up to 12.3 grams of dust, if a city roofs utilize green then the carbon dioxide over the city will be reduced by 80%.

  China's urban population density, land resource constraints, ground greening is very limited, poor urban environment, high PM concentration value, promote green roofs have great prospects. Statistics show that since 2005, Beijing 10 years to enforce green roofs, green green area but not impressive, the green roof area of only 3% of the total area of the city building roof, and a large number of green roofs withered was eradicated.

  The implementation of green roofs as long as the difficulty lies in the lack of awareness of green roof, high maintenance costs to worry about, the roof leaks and the like. To speed up urban green roofs, we must address the following issues:

  First breakthrough concept. Many residents of green roofs are poorly understood, there is a misunderstanding that planting flowers on the roof can cause water seepage, increase housing bearing weight, will have hidden dangers. After testing, each square meter roof loading capacity of more than 30 kg can be planted grass, most of the roof of the city have such capacity, no security problems. This requires publicity campaign to popularize the advantages of green roofs and security, so that residents and consciously accept the green roof.

  Second, the government should be funding grants. Green roof cost per square meter more than $ 400, above the ground greening, plus maintenance costs, the price is not low. These costs are paid by the individual or entity, so the lack of enthusiasm. Belong to urban greening public welfare, green roofs also belong to the category of urban greening, government promotion of green roofs, should be capital grants to undertake major funding. The Government should be actively pursued green roof pilot, so that we see the benefits. When residents benefit from being ecological effects, we will respond positively to the green roof.

  The third is in need of legal support. Green roofs are then developed into the city legal management, so that planning and building design, construction and green roof construction simultaneously. Compared with the architectural design of urban green roof China is decoupling, which need to be incorporated into the urban greening green roof system, three-dimensional protection. New construction project to fully take into account the need for green roof, improve the bearing capacity building.

  Fourth, to enhance the status and quality of green roofs will be incorporated into the overall planning of urban construction and management, well-designed, unified layout, the green roof and the city's personality, taste blend, green ground with shine and become over the city greenery.
