The Research Of Design Method Of Green Roofs In Cold Regions

Along with our country's urbanization,more and more urban land was occupied by construction;"the fifth facade" of the city is increasing sharply.Green space can be used to less and less in city,when the roof towards the sky which is not treated,it is time for a lot of absorption of heat from the sun at the same,and has led to a serious "heat island",a gradual deterioration of the urban environment.Green roof is green on the ground up to the roof,so not only it can make up for the lack of urban green space,but also played the role of urban heat island mitigation.Developed countries in recent decades,rapid development of green roof,made a lot of results,especially in the 21st century,the more rapid development.Although the green roof in China started in the 80s last century,but because of technical and financial reasons,development has been relatively slowly, it only began to speed up the pace of development in recent years,but the distribution is very uneven.Green roof in China mainly concentrated in the warmer southern regions,the northern region as a result of climate and economic reasons,it develop relatively slowly.And cold regions in green roof design is also a lack of a good summary,in view of the above problems, the problems will be discussed from the following aspects by the article.Research on the analysis of the cold regions of northern China at this stage in the promotion of roof greening methods and problems of the status quo on the basis of.Introduced promotional strategies of the foreign countries in the cold region,Made the promotion method of green roofs in the level of China's cold regions.Then making the green roofs the eco-effectiveness of green roofs from planting design,space design and the design of the roof form of the three aspects in cold regions,and through the method of anglicizing of available data,accessing to information,researching in field conducted in-depth aspects research in this field,In the end made up China's cold regions green roofs design method with suitable.
