借鉴物理学中的耦合理论,分析沿海城市经济系统、海洋生态环境系统与游艇旅游业系统三者间的耦合协调作用机理;构建耦合评价模型与指标体系,并基于改进的熵值法,对沿海16个游艇旅游发展重点城市三者的耦合度及耦合协调度进行实证研究;运用皮尔逊相关系数法探讨各因素间相互关系。结果表明:沿海城市经济、海洋生态环境和游艇旅游业发展水平的综合评价值并不高,可进一步分为城市经济滞后型、生态环境滞后型和游艇旅游业滞后型三种制约类型;区域内三大系统耦合度较高,但耦合协调度较低且存在明显的区域差异;系统内部各因素间相互关联。鉴于此,提出游艇城市应因地制宜,协调开发与保护关系,深化产业融合等建议,以促进三大系统较高层次的耦合协调发展。 相似文献

通过对中国游艇俱乐部相关数据的收集与分析,探讨游艇俱乐部的区域宏观区位特征和城市微观区位特征,并揭示出区位特征的核心影响因素。主要结论为：中国的游艇俱乐部主要集中在三大经济区,其中广东、海南、山东、上海和浙江等地的游艇俱乐部综合能力较强。中心城区和近郊区是游艇俱乐部的主要聚集地,纯游艇俱乐部和地产型游艇俱乐部为主要载体,有泊位的与无泊位的俱乐部在区位上高度重合。影响游艇俱乐部区位的因素既包括区域自然资源环境、经济水平、旅游业发展、上游游艇制造业,也包括游艇产业相关政策及区域海洋文化等因素。 相似文献

Yachts and recreational boats have been growing in popularity throughout the world. In the United States alone they have a 2% annual growth rate. This growth has created the market for new boats built with improved hull materials and new hull forms, propulsion motors and fabrication techniques. With this growth in boat designs and technology developments, it is useful to examine the current trends in pleasure boat design. This paper addresses the development and utilization of a relational pleasure boat database BOATDSS–Boat Decision Support System. The BOATDSS database contains the data on 850 boat designs. The Decision Support System portion of the BOATDSS is organized to use this data for decision support such as a buyer shopping or a builder examining the potential of a new boat entering the present boat market. Several results from BOATDSS are presented to illustrate its use during the conception and preliminary design of recreational boats. 相似文献

游艇作为新型休闲旅游项目在中国迅速兴起。海南的游艇旅游在政策支持、资源环境等方面优势突出。三亚作为海南建设国际旅游岛的排头兵,对游艇旅游的发展给予了充分的重视。但游艇俱乐部在运营管理方面反映出的绩效不佳。通过回顾相关研究成果,并实际调查三亚游艇俱乐部的运营现状,重点对运营机制与管理模式进行剖析,归纳游艇俱乐部面临的发展难题,提出游艇俱乐部通过明确市场定位、创新业务类型、推动与关联行业融合发展、开辟营销公关新思路、完善投资机制等途径实现管理模式优化,进而使游艇俱乐部的内部管理适应环境变化。 相似文献

The ability of a sailing yacht to re-right due to the effect of a breaking wave is investigated experimentally. Free and constrained physical models with varying mast height and centre of gravity were tested. To investigate the influence of retained mast height on sway force and roll moment, models were constrained by attachment to a force balance for sway motion tests in calm water and stationary tests in regular and breaking waves. Free model testing, with varying mast height and centre of gravity position, were carried out in breaking waves. For these tests, model motions in six degrees of freedom were measured using photogrammetry. The constrained tests showed that while the mast height had little effect on forces when stationary in waves it had a large effect when in sway motion. As models experience large sway motions when subject to a breaking wave the mast remnant plays a critical role in re-righting dynamics. This work demonstrates that re-righting probability is more dependent on mast height retention and wave characteristics than vertical centre of gravity. This conclusion has direct implications on re-righting safety assessment as the dominant design feature in most safety standards is the vertical centre of gravity. 相似文献

作为现代海洋旅游的重要组成部分,游艇旅游正随着人们收入水平的不断增长而得到蓬勃发展,引起了旅游管理者和学术界的高度关注。本文通过对国内外游艇旅游文献资料的全面检索和分析,发现国外学者对游艇旅游的研究时间较早,研究内容更加广泛和深入,主要包括游艇旅游基础概念探讨,游艇旅游需求与供给研究,游艇旅游对经济、社会文化和环境影响的研究,以及游艇旅游政府管理和协同治理研究等5个方面。而在研究方法上,国外主要采用多学科研究方法,注重实地调研和数据库的建立,通过模型构建与数理统计支撑定性描述。我国未来应不断拓展研究领域,完善游艇旅游理论和实践治理体系,借鉴国际经验探索游艇旅游本土化发展范式,并加强定量研究方法使用,以期为中国游艇旅游发展实践提供参考。 相似文献

It is important to understand flow characteristics and performances of sails for both sailors and designers who want to have efficient thrust of yacht. In this paper the viscous flows around sail-like rigid wings, which are similar to main and jib sails of a 30 feet sloop, are calculated using a CFD tool. Lift, drag and thrust forces are estimated for various conditions of gap distance between the two sails and the center of effort of the sail system are obtained. Wind tunnel experiments are also carried out to measure aerodynamic forces acting on the sail system and to validate the computation. It is found that the combination of two sails produces the lift force larger than the sum of that produced separately by each sail and the gap distance between the two sails is an important factor to determine total lift and thrust. 相似文献

为促进海南游艇旅游转型升级与空间布局优化，推动海南海洋经济高质量可持续发展，本文基于2013年、2017年、2021年海南游艇俱乐部、游艇会及游艇码头数据，利用标准差椭圆分析、平均最近邻指数、核密度分析、重心迁移模型对海南游艇旅游的时空演化特征进行研究，并利用近邻分析法、相关性分析法和政策文本分析法，从旅游资源禀赋、自然地理环境、区位交通条件、政策保障机制等四个维度剖析和阐释海南游艇旅游时空演化特征的影响因素。研究发现：（1）海南游艇旅游核心场所持续增加;（2）海南游艇旅游发展呈显著的空间聚集特征，聚集程度先上升后下降;（3）海南游艇旅游呈东北-西南走向迁移布局;（4）海南游艇旅游模式逐渐由“三亚-海口双核心”向“三亚单核心”演变;（5）自然地理环境和旅游资源禀赋是影响海南游艇旅游时空格局形成的基础性因素，区位交通条件是其时空演化特征的驱动性因素，政策支持是其时空演化形态的导向性因素。最后，对海南游艇旅游可持续发展提出四个方面的对策建议，以积极推动具有世界影响力的中国特色自由贸易港建设。 相似文献
