基于客流量预测的旅游公路投建决策研究

旅游公路的建设能够提升景区通达性,为景区带来经济效益,同时也需要大量的资金投入.由于建设资金的限制,需要根据旅游公路收益率对实际投建项目进行决策."旅游公路收益率计算模型"通过对景区在不同旅游交通条件下的客流量进行预测,定量分析旅游公路建设对客流量的影响,计算出不同旅游公路建设项目的收益率.该模型中客流量预测以游客对景区的"旅游资源吸引力"和"旅游阻力"评价分布曲线为基础,认为游客对景区做出选择是基于对该景区的"旅游资源吸引力"评估大于"旅游阻力"评估.同时以我国西南地区某县为例,对该县旅游公路建设项目进行投建决策分析.     

京唐港自然条件及入海航道泥沙回淤

京唐港为我国在砂质-粉砂质海岸建设的第一个深水港,自1992年竣工以来,已多次发生航道骤淤现象。为掌握泥沙骤淤机制,总结砂质-粉砂质海岸建港经验,通过分析京唐港发生泥沙骤淤的海岸动力条件和泥沙回淤特点,指出大风浪条件下存在宽阔的破波带和"广义沿岸输沙带",而秋冬季强风浪大量扬动并输移近海区粉砂质底质是航道骤淤的主要原因;掌握大风浪条件下粉砂质岸滩泥沙运动规律,特别是底层高浓度的特点,是估算粉砂质岸滩挖槽内骤淤量的关键。研究成果可为在砂质-粉砂质海岸建港选址和挡沙堤建设提供借鉴。     

高职《旅游概论》教材特色体系的构建

我国的高职旅游教材目前尚处在摸索建设阶段,基本上没有摆脱本科教材的窠臼,没有形成高职教育特色。本文以高职《旅游概论》为例,从教材的编写体例、结构方式、内容选择等方面探讨了高职旅游教材应有的特色。     

Institutions Shaping Coastal Ecosystems: The Algarve Case

Water and land use have changed dramatically over the last thirty years in Southern European coastal zones. For climatic and economic reasons coastal tourism development is often accompanied by simultaneous intensification of agricultural activity. The literature highlights a number of emerging resource pressures. The intensity of land use, excessive infrastructure development, and overexploitation of water resources pose the primary problems. Unsustainable development is often ascribed to mal-performing institutions (e.g., environmental management and land use planning), but there is a lack of studies analyzing the way in which institutions contribute to the problem. We address this gap by devising an analytical strategy that combines function analysis with the analysis of governance structures, property rights, and actors. This strategy is applied to the analysis of changes in ecosystem functions of the Portuguese coastal zone of the Algarve between the mid-eighties and today. Based on the analysis we call for an improvement of the performance of formal institutions in the Algarve. Actors in charge of implementing reformed institutions have to be given the financial and human means to implement formal property rights. Furthermore, entitlements for resource exploitation and interconnected transactions should not anymore be taken for granted. Specifically, institutions to control land use should be made more effective and incentives, that exclusively promote development, such as the construction tax, need to be questioned.     

Surfer and Beachgoer Responsiveness to Coastal Water Quality Warnings

Fecal contamination of coastal waters has led local public health agencies to issue tens of thousands of beach advisories annually and to advise against ocean swimming and surfing for 72 hours following a rain. The responsiveness of recreationists to beach advisories and the “72 hour rule” is estimated by merging four years of multi-daily surfer and beachgoer counts at one beach in Southern California with hourly data on beach advisories, recent precipitation, meteorological conditions, and the UCSB academic calendar. Both surfing and beach-going decreased significantly following rainfall in response to the 72 hour rule, showing that recreationists are willing to engage in health risk-reducing avoiding behavior. However, neither surfing nor beach-going decreased significantly during beach advisories. Surfers were significantly more responsive to beach advisories during dry periods than during wet periods, consistent with the hypothesis that recreationists are most likely to respond to a risk warning that they believe provides accurate and additional health risk information beyond what they can observe personally. Additional studies of beach advisories elsewhere could clarify whether responsiveness to beach advisories varies by recreationist demographic, recreational activity, frequency of advisories, or frequency of repeat visitation. Increasing the accuracy and additional information provided by beach advisories, as proposed by numerous authors, could lead to increased responsiveness.     

日照港退岸还海项目人工沙滩拦沙堤布置研究

平直岸线建设人工沙滩时,在没有掩护条件下,通常会在波、流的作用下形成单向的持续输运,人工沙滩难以存留。文章以日照港退岸还海项目为例,基于抛物线型岬湾平衡岸线理论,通过数学模型试验确定了沙滩的铺沙范围和南拦沙堤的布置方案。同时,针对侵蚀比较严重的北侧和中部位置对比分析中部挡沙堤、离岸岛堤、北部拦沙堤等不同的掩护形式的景观性和对泥沙运动的影响,比选出设置北拦沙堤进行掩护,以沙滩流失量和稳定岸滩宽度作为主要指标,通过物理模型试验进一步确定了北侧拦沙堤的布置方案,并对拦沙堤的整体布置进行了验证。     

Planning Strategies for Mangrove and Saltmarsh Changes in Southeast Australia

Estuarine habitats of southeast Australia have been undergoing changes characterized by a reduction of saltmarsh and an increase of mangroves. Incorporated into these changes have been mangrove migration into saltmarsh areas, thus contributing to the latter's decline. At the same time, rapid and extensive change in the catchments of many estuaries has occurred as a result of urban and rural development. It has been estimated that the changes observed between mangrove and saltmarsh wetland vegetation is caused by a series of processes, including urbanization and increased population pressure, increased rainfall, increased nutrients, mangroves recolonizing previously cleared areas, engineering works and subsequent altered tidal patterns, sea-level rise, and subsidence of intertidal flats. Planning strategies are suggested that can be implemented in an integrated manner to mitigate the threats from these processes and to ensure the sustainable management of mangrove and saltmarsh wetlands.
