The Study On The Construction Techniques And Use Of Green Roofs

Because of the rapid development of cities,and the large quantities of Construction and Development, the city's ecological environment has been destroyed. There are conflict between the economic development, the urbanization and the urban environmental. Development does not necessarily imply the destruction of urban.Development should take the economic ,the ecological to be coordinated and sustainable development. The green roof, which from the open field, in the board structure of the green form, can effectively make up for the lack of urban greening, the city will no longer be indifferent to the reinforced concrete, and no longer the poor monotonous environment, the city becomes Vibrant, thriving .Since the opening up of China's urbanization into the high-speed development stage, the urban environment have been damage Seriously.The environmental issues have become increasingly prominent. To improve the urban environment, the green roof in China has been gradually developed. A large-scale construction of green roof is rising.In this paper against the current state of development about green roofs, summed up the advanced construction technology, its classification, more comprehensive introduction to the construction of the relevant technical knowledge and its application in China and put forward some proposals thinking. Mainly include:1.The briefly of green roof. Including the development of history,Overview of the role of green roofs, characteristics, classification, and the green roof's design principles.2.Vegetation options: the roof of vegetation's growen environment, the principle of how to choice the vegetation, the types of the vegetation , the scope of application, and the design method about the vegetation.3.Construction technology: categories the construction technology, from its security technology, construction, maintenance, conversion technology, and the new technology of these five areas of sub-item. Analysis the typical examples which at home and abroad, so that the readers can get a more comprehensive understanding about the various construction technology Part of of green roof technology content and the development.4.The thinking of use: To the use of green roofs, this paper analysis about the status of development and the emergence of a number of issues, and done a feasibility analysis from the perspective of economic and energy for their development and make recommendations from the construction cost, type of use, policy Regulations and people's ideological awareness of its use...
