Edible landscape design is a new type of landscape system with productivity,sustainability and ecology,which is mainly composed of edible plants for human beings.The construction of edible landscape is the organic combination of "ecology,life and production",which is produced in response to the characteristics of China's national conditions and the needs of the times,and provides new ideas for the design of agricultural landscape in China.In this paper,through literature review,case analysis and other research methods,the domestic and foreign edible landscape design research summary is sorted out,the actual cases of edible landscape design at home and abroad are studied and explored,and the general situatio n of edible landscape construction at home and abroad is summarized,the main results are as follows:according to the statistical data of the questionnaire survey,the long-term residents in the residential area are the elderly and children,and the elderly aged 60 years and over account for 44.5% of the respondents;the types of edible landscape construction sites in the survey area are: front and back houses of houses;both sides of roads;indoors of residents;building walls,scaffolds,fences;flower beds,tree pools and flower ponds;there are 16 edible trees,10 shrubs and 33 other edible plants in old residential communities affiliated to universities in Harbin.Property management in these areas basically does not interfere with the cultivation of fruits a nd vegetables,and even in some residential areas there is no fixed property management.Subsequently,according to the research content and the actual situation of edible landscape construction in residential areas,the problems that may be faced in the con struction of edible landscape in old residential areas,and the residents' opinions on the transformation design of edible landscape in residential areas,the feasibility of edible landscape design in old residential areas affiliated to universities in Harbin was found.The economic and ecological benefits of edible landscape construction in old residential areas and the advantages of edible landscape construction in old residential areas are verified and analyzed.This pave the way for the principles and Strategies of edible landscape design in old residential areas affiliated to universities in Harbin.Finally,under the guidance of "landscape ecology" and "elasticity concept",taking the old residential area affiliated to Northeast Agricultural University as an example,the edible landscape design and corresponding design principles are put forward.The operable idle green space of the residential area is designed according to the types of edible landscape and combined with various ecological application technologies,such as fish and vegetable symbiosis,rainwater collection and raw vegetable.Material composting can provide reference for landscape reconstruction of old residential areas in the future.
