Application Of Productive Landscape In Roof Greening

The rapid development of urbanization brings about the rapid development of urban and rural regional construction.The rapid construction of cities and urban and rural areas leads to the gradual reduction of agricultural cultivated land and the serious imbalance of ecosystem.While meeting the needs of people’s convenient life,many problems are gradually highlighted,such as the destruction of the natural environment,the significant benefit of heat island and the substantial reduction of green space.People are more and more eager to get close to nature,return to nature,and try to pursue ecological balance from the vertical space of the city.The roof of "the fifth facade of the city" has attracted much attention.The development of urban agriculture makes the development of roof greening more diversified.Productivity has certain economic,cultural and ecological functions,and can create energy.It is a compound form of landscape,living on the roof Productive landscape planting can not only improve the ecological benefits,but also enhance the economic and social benefits,in line with the modern people’s demand for urban green space and agricultural production.Taking the productive plant landscape on the roof of urban buildings as the research object,this paper analyzes the production and development background of the productive planting of urban agriculture,analyzes its development reasons,combines with the relevant landscape planning and design principles,compares the design example mode analysis,combines the productive characteristics of urban agriculture with the roof greening,and systematically analyzes the feasibility and advantages of the productive landscape in the roof construction Disadvantages and necessity.Based on the ornamental function,educational function and production function,this paper scientifically analyzes the relevant supporting technical facilities,which can provide strong guidance and guarantee for the design and planning of productive landscape in the building roof in the future.It is mainly divided into several partsIn the first part,the research background,purpose and significance of this topic are described,and the main research contents and methods,as well as the article structure are introduced.The second part combs the related concepts,main types,development motivation and evolution process of urban agricultural productive planting behavior,summarizes the development status and research results,analyzes the existing problems,and explores the combination of urban building roof greening and agricultural planting,so as to lay the foundation for this research.The third part analyzes the advantages of productive landscape roof planting in the city,through field research and questionnaire to understand the public’s demand for roof greening and productive planting,makes a comprehensive evaluation of the investigated sites and puts forward suggestions for improvement,and analyzes the feasibility of building productive landscape on the roof.In the fourth part,the landscape function,education function and production function of productive roof greening are studied theoretically.The landscape construction mode,natural education mode and production breeding mode of productive plants are summarized.Combined with relevant supporting technologies,the basic factors and design strategies of productive roof greening are summarized.The fifth part,the combination of theory and practice,selects a building roof in Zhengzhou city to enhance the productive plant landscape construction,verifies the research theory,enriches the research content and improves the research results.The sixth part summarizes the main research content of this paper.
