It is a demonstration project of "Modern Ecological Citizen Orchard" in Sanya, which enriches the environmental landscape resources of Sanya, improves the urban quality of Sanya and realizes the sustainable development of an eco-city. At the same time, the construction of urban orchards is organically combined with the effective protection and restoration of riparian ecosystems. Based on Hainan's characteristic orchard habitat, we will create a variety of ecological landscape experience and sightseeing space, and provide citizens and tourists with a base to experience Sanya's unique farming culture. At the same time of eco-sightseeing, leisure and vacation, increasing agricultural knowledge is conducive to carrying out popular science publicity and education and raising public awareness of ecological environment protection.
