The layout included orderly development and overal planning, connection of three expressways and middle area for recreation and the rest for sightseeing; the site selection should develop depending on central cities, relying on major projects and famous mountains or landscapes; the connotation in-volved exploitation of farming culture, presenting national customs of indigenous people, highlights given to island and coasts and emphasizing tropic agriculture. What＇s more, the suggestions were proposed to advance leisure agriculture of Hainan, including to formulate scientific planning to lead leisure agriculture develop-ment, to give policy supports and enterprise management, to improve promotion and broadening market and to enhance education and improve industry quality. On basis of lots of data and examples, the research enriched the content of leisure agricul-ture in Hainan, which is conductive to development of Hainan leisure agriculture, and of significance for construction of leisure agriculture sites and supports of the agriculture by government.展开更多
