中文摘要：

三亚是我国唯一的热带海滨旅游城市，亚龙湾、大东海、海坡3个海滨度假群落已经形成。3种各具特色的度假群落齐聚三亚并非偶然，是三亚相对垄断性的海滨气候资源与国内海滨度假需求相互作用的结果．在现场踏勘和文献研究的基础上，对3个度假群落的形态特征进行了比较研究，发现它们在土地利用及形态方面存在显著不同．亚龙湾是综合封闭塑海滨度假区，大东海属于城市海滩型度假区，海坡属线性开放型度假区．不同的度假区形态和外部环境对区内旅游设施的消费档次和开发效益产生了直接影响，亚龙湾内的度假消费档次最高，大东海和海坡次之。度假区开发模式和规划控制力度的不同可能是造成度假区形态差异的重要原因．研究结论对于国内海滨度假区规划开发具有借鉴和参考价值．

英文摘要：

Resort morphology is concerned with the land use, built forms and associated functions of resort destination, which has been one of western geographer interests on coastal resort research. Resort morphology is closely related with resort planning. Insufficient attention has been paid in the coastal resort morphology among domestic scholars, which leads to some flaws in coastal resorts planning. Three types of coastal resorts as Yalong Bay, Dadong Hal, Haipo have come into being in Sanya, which is the only tropic coastal city in China. Based on field survey and literature review, the paper gives comparative study on resorts morphology and development performance of three coastal resorts. The findings include two aspects. The paper distinguishes three different resort morphology from respects of resort spatial pattern with local community, openness of beach, types and quality of commercial facilities within resorts, spatial patterns between resort hotels and beach. Second, resorts morphology have great impacts on the consumption and development level, with indication on the average rate of resort hotels and local tax contribution. Yalong Bay ranks highest, followed by Dadong Hal and Hal po resort. The paper finds out the competitiveness of coastal resort not only lies on amenity quality, hospitality service, hotel brand, and location, but also on exclusiveness of vacation consumption space, which is greatly influenced by resort morphology. It is assumed that the development model and different ways of planning and control is the inner cause of different coastal morphology formation.
