[ Results] The results showed that Spartina alterniflora had the best growth pattern in the loam. The morphological factors of fructification of S. altemiflora grown in sand were larger then in others. In the three growth conditions the order of quantitative characteristics of fructification of S. alterniflora was clay 〉 sand 〉 loam and the seeds in spikelet at top position were more maturity than those at the button position. [ Conclusion] In good condition, the Spartina altemiflora growth was vigor but the ratio of seed-setting was low.展开更多

The present situation and development prospects of tropical leisure agro-tourism in the context of constructing International Tourism Island in Hainan are introduced in this study, SWOT analysis of tropical leisure agro-tourism in Hainan is conducted, causes of imperfect tropical leisure agro-tourism in Hainan Island are elaborated such as insufficient understanding and investment, fragile infrastructure and lack of overall tourism planning despite its abundant tropical agricultural resources, marine resources, forest resources and ecological resources as well as convenient transportation. Combining with the opportunities and challenges in developing tourism industry, targeted strategies are proposed for promoting the tropical leisure agro-tourism, that is, enhancing understanding about leisure agro-tourism; determining the target and orientation of tourism planning through basic classification, properly defining functional divisions and spatial layout; improving relevant laws and regulations about tourism industry; attaching more importance in attracting alien investment; fully developing the tropical, marine, green and ecological features of tropical leisure agro-tourism in Hainan Island; cultivating resources, scenic spots and products of different types respectively in tourism development, especially culturing typical products; protecting ecological environment, implementing sustainable development of tourism industry; making innovations in marketing, accurately subdividing tourism market.展开更多
