Life function, also known as social function. As an integral part of urban culture and social life, agriculture provides social communication and spiritual and cultural life needs between citizens and farmers through agricultural activities such as sightseeing and leisure agriculture, farming culture and folk culture tourism.

Demonstration and educational function. Suburban agriculture has the function of "window agriculture", and because of its high degree of modernization, it plays a demonstration and driving role in other regions.
