Concept of agricultural heritage systems was introduced. As a new heritage type, agricultural heritage systems focus on agricultural systems and its related biodiversity, landscape, land use system, traditional agricultural knowledge and experience, practices, and also the relative cultural diversity which make it the best expression of "agricultural heritage systems are not about the past, it is about the future". Studies about agricultural systems are mainly concentrating on pilot systems, about biodiversity conservation, eco-mechanism and ecological values of the systems, traditional knowledge conservation, community involvement, policies and regulations about the dynamic conservation and adaptive management, and also ways of dynamic conservation and exploration. Being considered as a dynamic approach of protecting agricultural heritage systems, agricultural heritage tourism was compared with rural tourism, agricultural tourism and "farm-stay". Agricultural heritage tourism is actually a type of heritage tourism, and one of its important functions is to build cultural identity of the heritage site and enhance awareness of the local community to conserve their assets. And the studies show that agricultural heritage systems as a kind of tourist resources have great development potentials.
