Low Maintenance Simple Roof Greening Design And Technology Research

With the rapid development of C hina’s economy,accelerate the process of city,city population is more and more intensive,available lands in the city are become less,more and more pressure on the greening of the city.The contradiction between the development of landscape architecture and land use is the key problem of the current development of urban landscape.In order to solve the problem o f bad environment and promote the construction of ecological garden,on the basis of ensuring the existing plane greening,green must be developed in many ways,such as green space,aerial garden and so on.At present,there are still many problems in the China’s roof greening,such as: lack of consideration of local climate and cultural customs,no clear design positioning,maintenance difficulties and high cost.Therefore,it is urgent to develop a simple and efficient way to solve the contradiction between the huge demand and slow development.The first step of this paper analyzes the history and trend of roof greening at China and abroad.The second step through the analysis of the traditional roof landscape types and problems,to analyze and explore Low Maintenance Simple Roof Greening’s roof greening crowd behavior design.Then,through the analysis of different regions at C hina and abroad,combined with the characteristics of Low Maintenance and Simple Roof Greening,this paper explores the Low Maintenance Simple Roof Greening design in different areas.The third step,mainly from load,irrigation,water,plant selection,and other aspects of retaining Low Maintenance Simple Roof Greening engineering technology,and the retaining structure are tested,and the feasibility of retaining structure.The fourth step,To test the substrate of callisia repens which is mainly used in Low Maintenance Simple Roof Greening,in order to achieve the purpose of improving the economic benefit,but also the promotion of low maintenance is one of the important factors of simple roof greening technology,the garden soil,coir and peat soil ratio of 4:3:3 was the most suitable for callisia repens.Finally,based on the above research,summed up the Low Maintenance Simple Roof Greening has many advantages such as,investment and management of low cost,light weight,easy popularization.And explore the landscape pattem of Low Maintenance Simple Roof Greening,application of Maintenance Simple Roof Greening’s construction technology and the popularization value.
