Research On Key Technologies Of Roof Greening Design Of Public Buildings In Shenzhen

With the development of urbanization in China,people's requirements for quality of life are increasing.However,the importance of roof greening as a symbol of higher living standards has not received enough attention.The deep value of roof greening has not been widely recognized.know.Therefore,in order to keep up with the pace of the times and face the ever-increasing demands of the residents for ecological civilization,the city urgently needs roof greening to provide users with better functions and space services.The purpose and destination of this study is to explore a more high-quality roof green space for the contemporary.Based on the concept of “beautiful China” and“sponge city” advocated by the state,this paper refines the new requirements for roof greening in the new era.By comparing the development status at home and abroad,understand their own shortcomings,and clarify the direction of efforts.Then through the study of the basic theory,deepen the understanding of the classification and structure of the roof greening.Afterwards,the problems of traditional building roof greening are summarized,including excessive load,easy material damage,insufficient durability,soil loss,low plant survival rate,and then aiming at these problems,and looking for a suitable breakthrough.Targeted optimization of each part of the roof greening structure,respectively,to solve various problems,such as the use of new materials,the use of new plants,the development of new substrates and the adoption of new practices,and on this basis The whole set of optimization system makes the roof greening sustainable,which makes it have a longer service life and better quality effect to better serve the users.Finally,the research results are applied to the actual project,and the ecological,social and economic benefits are analyzed to prove the effect of the optimized design.
