Agriculture Characterized by City:Concept,Nature,Key of Research

Fuzzy on the concept of "urban agriculture" largely hampered the development of research.The reason of the fuzzy and dispute is because this concept is used to summarize three kinds of different essentially agricultural activity in different occasions.Considering on the need to clarify the concepts,"urban agriculture" and "agriculture on rural suburb of city" and "agriculture characterized by city" can be used to summarize these three kinds of agricultural activity respectively,and we should focus research on "agriculture characterized by city"."Agriculture characterized by city" is the ideal agricultural pattern which is based on "agriculture on rural suburb of city " which is existing agriculture in natural."Agriculture characterized by city" is the concept which emphasizes functional characteristics as well as being based on the region,and which emphasize macroscopic system as well as being based on micro unit.The issue on development of "agriculture characterized by city" is essentially optimizing allocation of city resources which is adapt to the development of the urban.So,the basic research methods should be optimization on agriculture production structure on rural suburb of city from the perspective of agricultural location.Research on "agriculture characterized by city" should focus on city resources and environment condition,micro unit production structure mode,macro industrial structure and regional layout,technology integration and innovation,and organization model and support policy,etc.
